For the +targets it could support, it worked well. It had limitations inherent in +its design that would be difficult to resolve, so a major effort was made +and gcc version 2 was the result. When we had gcc2 in a useful state, +development efforts on gcc1 stopped and we all concentrated on making +gcc2 better than gcc1 could ever be. This is the kind of step forward +we want to make with egcs. + +In brief, the three biggest differences between egcs and gcc2 are +these: + + + More rexamination of basic architectual decisions of + gcc and an interest in adding new optimizations; + + working with the groups who have fractured out from gcc2 (like + the Linux folks, the Intel optimizations folks, Fortran folks) + including more front-ends; and finally + + An open development model (see below) for the development process. + + +These three differences will work together to result in a more +useful compiler, a more stable compiler, a central compiler that works +for more people, a compiler that generates better code. + + +There are a lot of exciting compiler optimizations that have come +out. We want them in gcc. There are a lot of front ends out there for +gcc for languages like Fortran or Pascal. We want them easily +installable by users. After six years of working on gcc2, we've come +to see problems and limitations in the way gcc is architected; it is +time to address these again. + + +What is an open development model? + +With egcs, we are going to try a bazaar style[1] approach to its +development: We're going to be making snapshots publically available +to anyone who wants to try them; we're going to welcome anyone to join +the development mailing list. All of the discussions on the +development mailing list are available via the web. We're going to be +making releases with a much higher frequency than they have been made +in the past: We're shooting for three by the end of 1997. + +In addition to weekly snapshots of the egcs development sources, we +are going to look at making the sources readable from a CVS server by +anyone. We want to make it so external maintainers of parts of egcs +are able to commit changes to their part of egcs directly into the +sources without going through an intermediary. + +There have been many potential gcc developers who were not able to +participate in gcc development in the past. We these people to help in +any way they can; we ultimately want gcc to be the best compiler in the +world. + +A compiler is a complicated piece of software, there will still be +strong central maintainers who will reject patches, who will demand +documentation of implementations, and who will keep the level of +quality as high as it is today. Code that could use wider testing may +be intergrated--code that is simply ill-conceived won't be. + +egcs is not the first piece of software to use this open development +process; FreeBSD, the Emacs lisp repository, and Linux are a few +examples of the bazaar style of development. + +With egcs, we will be adding new features and optimizations at a +rate that has not been done since the creation of gcc2; these additions +will inevitably have a temporarily destabilizing effect. With the help +of developers working together with this bazaar style development, the +resulting stability and quality levels will be better than we've had +before. + +cathedral-vs-bazaar[1] + We've been discussing different development models a lot over the + past few months. The paper which started all of this introduced two + terms: A cathedral development model versus a bazaar + development model. The paper is written by Eric S. Raymond, it is + called `` http://locke.ccil.org/~esr/writings/cathedral.html" The + Cathedral and the Bazaar''. The paper is a useful starting point + for discussions. + + + +bits/libc-lock.h: No such file or directory +egcs includes a tightly integrated libio and libstdc++ implementation which +can cause problems on hosts which have libio integrated into their C library +(most notably Linux). + +We believe that we've solved the major technical problems for the most +common versions of libc found on Linux systems. However, some versions +of Linux use pre-release versions of glibc2, which egcs has trouble detecting +and correctly handling. + +If you're using one of these pre-release versions of glibc2, you may get +a message "bits/libc-lock.h: No such file or directory" when building egcs. +Unfortunately, to fix this problem you will need to update your C library to +glibc2.0.5c. + +Late breaking news: we may have at least a partial solution for these +problems. So this FAQ entry may no longer be needed. + + +`_IO_stdfile_0_lock' was not declared in this scope +If you get this error, it means either egcs incorrectly guessed what version +of libc is installed on your linux system, or you incorrectly specified a +version of glibc when configuring egcs. + +If you did not provide a target name when configuring egcs, then you've +found a bug which needs to be reported. If you did provide a target name at +configure time, then you should reconfigure without specifying a target name. + + +Problems building the Fortran compiler +The Fortran front end can not be built with most vendor compilers; it must +be built with gcc. As a result, you may get an error if you do not follow +the install instructions carefully. + +In particular, instead of using "make" to build egcs, you should use +"make bootstrap" if you are building a native compiler or "make cross" +if you are building a cross compiler. + +It has also been reported that the Fortran compiler can not be built +on Red Hat 4.X linux for the Alpha. Fixing this may require upgrading +binutils or to Red Hat 5.0; we'll provide more information as it becomes +available. + + +Problems building on MIPS platforms +egcs requires the use of GAS on all versions of Irix, except Irix 6 due +to limitations in older Irix assemblers. + + Either of these messages indicates that you are using the MIPS assembler +when instead you should be using GAS. + + as0: Error: ./libgcc2.c, line 1:Badly delimited numeric literal + .4byte $LECIE1-$LSCIE1 + as0: Error: ./libgcc2.c, line 1:malformed statement + + + + as0: Error: /home/law/egcs_release/gcc/libgcc2.c, line 1:undefined symbol in expression + .word $LECIE1-$LSCIE1 + + + For Irix 6, you should use the native assembler as GAS is not supported +on Irix 6. + + +Problems with exception handling on x86 platforms +If you are using the GNU assembler (aka gas) on an x86 platform and +exception handling is not working correctly, then odds are you're using a +buggy assembler. + +We recommend binutils-2.8.0.1.15 or newer. +"ftp://tsx-11.mit.edu/pub/linux/packages/GCC/binutils-2.8.1.0.15.tar.gz binutils-2.8.0.1.15 source +ftp://tsx-11.mit.edu/pub/linux/packages/GCC/binutils-2.8.1.0.15.bin.tar.gz binutils-2.8.0.1.15 x86 binary for libc5 +ftp://tsx-11.mit.edu/pub/linux/packages/GCC/binutils-2.8.1.0.15.glibc.bin.tar.gz binutils-2.8.0.1.15 x86 binary for glibc2 +Or, you can try a +ftp://ftp.cygnus.com/pub/egcs/infrastructure/gas-970915.tar.gz binutils snapshot; however, be aware that the binutils snapshot is untested +and may not work (or even build). Use it at your own risk. + + +Bootstrap comparison failures on HPs +If you bootstrap the compiler on hpux10 using the HP assembler instead of +gas, every file will fail the comparison test. + +The HP asembler inserts timestamps into object files it creates, causing +every file to be different. The location of the timestamp varies for each +object file, so there's no real way to work around this mis-feature. + +Odds are your compiler is fine, but there's no way to be certain. + +If you use GAS on HPs, then you will not run into this problem because +GAS never inserts timestamps into object files. For this and various other +reasons we highly recommend using GAS on HPs. + + +Bootstrap loops rebuilding cc1 over and over +When building egcs, the build process loops rebuilding cc1 over and +over again. This happens on mips-sgi-irix5.2, and possibly other platforms. + +This is probably a bug somewhere in the egcs Makefile. Until we find and +fix this bug we recommend you use GNU make instead of vendor supplied make +programs. + + +Dynamic linker is unable to find GCC libraries +This problem manifests itself by programs not finding shared libraries +they depend on when the programs are started. Note this problem often manifests +itself with failures in the libio/libstdc++ tests after configuring with +--enable-shared and building egcs. + +GCC does not specify a runpath so that the dynamic linker can find dynamic +libraries at runtime. + +The short explaination is that if you always pass a -R option to the +linker, then your programs become dependent on directories which +may be NFS mounted, and programs may hang unnecessarily when an +NFS server goes down. + +The problem is not programs that do require the directories; those +programs are going to hang no matter what you do. The problem is +programs that do not require the directories. + +SunOS effectively always passed a -R option for every -L option; +this was a bad idea, and so it was removed for Solaris. We should +not recreate it. + + +Unable to run the testsuite +If you get a message about unable to find "standard.exp" when trying to +run the egcs testsuites, then your dejagnu is too old to run the egcs tests. +You will need to get a newer version of dejagnu; we've made a +<a href="ftp://ftp.cygnus.com/pub/egcs/infrastructure/dejagnu-971028.tar.gz"> +dejagnu snapshot available until a new version of dejagnu can be released. + + +How to build a cross compiler + Building cross compilers is a rather complex undertaking because they +usually need additional software (cross assembler, cross linker, target +libraries, target include files, etc). + + We recommend reading the <a href="ftp://ftp.cygnus.com/pub/embedded/crossgcc/FAQ-0.8.1"> +crossgcc FAQ for information about building cross compilers. + + If you have all the pieces available, then `make cross' should build a +cross compiler. `make LANGUAGES="c c++" install'will install the cross +compiler. + + Note that if you're trying to build a cross compiler in a tree which +includes binutils-2.8 in addition to egcs, then you're going to need to +make a couple minor tweaks so that the cross assembler, linker and +nm utilities will be found. + +binutils-2.8 builds those files as gas.new, ld.new and nm.new; egcs gcc +looks for them using gas-new, ld-new and nm-new, so you may have to arrange +for any symlinks which point to <file>.new to be changed to <file>-new. + + +Snapshots, how, when, why + We make snapshots of the egcs sources about once a week; there is no +predetermined schedule. These snapshots are intended to give everyone +access to work in progress. Any given snapshot may generate incorrect code +or even fail to build. + +If you plan on downloading and using snapshots, we highly recommend you +subscribe to the egcs mailing lists. See <a href="index.html#mailinglists"> +mailing lists on the main egcs page for instructions on how to subscribe. + +When using the diff files to update from older snapshots to newer snapshots, +make sure to use "-E" and "-p" arguments to patch so that empty files are +deleted and full pathnames are provided to patch. If your version of +patch does not support "-E", you'll need to get a newer version. Also note +that you may need autoconf, autoheader and various other programs if you use +diff files to update from one snapshot to the next. + + +How to install both egcs and gcc2 +It may be desirable to install both egcs and gcc2 on the same system. This +can be done by using different prefix paths at configure time and a few +symlinks. + +Basically, configure the two compilers with different --prefix options, +then build and install each compiler. Assume you want "gcc" to be the egcs +compiler and available in /usr/local/bin; also assume that you want "gcc2" +to be the gcc2 compiler and also available in /usr/local/bin. + +The easiest way to do this is to configure egcs with --prefix=/usr/local/egcs +and gcc2 with --prefix=/usr/local/gcc2. Build and install both compilers. +Then make a symlink from /usr/local/bin/gcc to /usr/local/egcs/bin/gcc and +from /usr/local/bin/gcc2 to /usr/local/gcc2/bin/gcc. Create similar links +for the "g++", "c++" and "g77" compiler drivers. + + +Problems building Linux kernels +If you installed a recent binutils/gas snapshot on your Linux system, +you may not be able to build the kernel because objdump does not understand +the "-k" switch. The solution for this problem is to remove /usr/bin/encaps. + +You may get an internal compiler error compiling process.c in newer +versions of the Linux kernel on x86 machines. This is a bug in an asm +statement in process.c, not a bug in egcs. XXX How to fix?!? + +You may get errors with the X driver of the form +_X11TransSocketUNIXConnect: Can't connect: errno = 111 + +It's a kernel bug. The function sys_iopl in arch/i386/kernel/process.c +does an illegal hack which used to work but is now broken since GCC optimizes +more aggressively . The newer 2.1.x kernels already have a fix which should +also work in 2.0.32. + + +Virtual memory exhausted error + This error means your system ran out of memory; this can happen for large +files, particularly when optimizing. If you're getting this error you should +consider trying to simplify your files or reducing the optimization level. + +Note that using -pedantic or -Wreturn-type can cause an explosion in the +amount of memory needed for template-heavy C++ code, such as code that uses +STL. Also note that -Wall includes -Wreturn-type, so if you use -Wall you +will need to specify -Wno-return-type to turn it off. + + +GCC can not find GAS +Some configurations like irix4, irix5, hpux* require the use of the GNU +assembler intead of the system assembler.

We want them in gcc. There are a lot of front ends out there for +gcc for languages like Fortran or Pascal. We want them easily +installable by users.

We thank them for their -contribution to our efforts. - -Kyoto Micro Computer of Japan regularly gives us 10% of their GNU-related -sales. - -Mr. Hiroshi, Mr. Kojima, and the other authors of the `Linux Primer' in Japan -have donated money from the sales of their book. - -Infomagic has continued to make sizable donations to the FSF. - -At the request of author Arnold Robbins, Specialized Systems Consultants, Inc. -continues to donate 3% of their profits from selling `Effective AWK -Programming'. We would also like to acknowledge the many SSC authors who -have donated their royalties and fees to the FSF. - -In the long run, the success of free software depends on how much new free -software people develop. Free software distribution offers an opportunity to -raise funds for such development in an ethical way. These redistributors -have made use of the opportunity. Many others let it go to waste. - -You can help promote free software development by convincing for-a-fee -redistributors to contribute--either by doing development themselves or by -donating to development organizations (the FSF and others). - -The way to convince distributors to contribute is to demand and expect this -of them. This means choosing among distributors partly by how much they give -to free software development. Then you can show distributors they must -compete to be the one who gives the most. - -To make this work, you must insist on numbers that you can compare, such as, -"We will give ten dollars to the Foobar project for each disk sold." A vague -commitment, such as "A portion of the profits is donated," doesn't give you a -basis for comparison. Even a precise fraction "of the profits from this -disk" is not very meaningful, since creative accounting and unrelated -business decisions can greatly alter what fraction of the sales price counts -as profit. - -Also, press developers for firm information about what kind of development -they do or support. Some kinds make much more long-term difference than -others. For example, maintaining a separate version of a GNU program -contributes very little; maintaining a program on behalf of the GNU Project -contributes much. Easy new ports contribute little, since someone else would -surely do them; difficult ports such as adding a new CPU to the GNU compiler -or Mach contribute more; major new features & programs contribute the most. - -By establishing the idea that supporting further development is "the proper -thing to do" when distributing free software for a fee, we can assure a -steady flow of resources for making more free software. - - - -Help from Free Software Companies -********************************* - -When choosing a free software business, ask those you are considering how -much they do to assist free software development, e.g., by contributing money -to free software development or by writing free software improvements -themselves for general use. By basing your decision partially on this -factor, you can help encourage those who profit from free software to -contribute to its growth. - -Wingnut (SRA's special GNU support group) supports the FSF by purchasing -Deluxe Distribution packages on a regular basis.

Volunteers with a PC are therefore eagerly sought to - get the 0.2 release and compile their favorite Unix programs and games. - - Daily snapshots of the Hurd sources are now available for those that - want to see the latest (non-stable) version; see the Hurd page on the - FSF Web site, `http://www.gnu.ai.mit.edu', for more information. - - * New Source Code CD! (*note July 1997 Source Code CD-ROMs::.) - - We are releasing the July 1997 (Edition 10) Source Code CD-ROM this - month. Once again, it is a two disk set. It includes several new - packages: `aegis', `cook', `guavac', `lesstif', `prcs', `rsync', `swarm', - & `vera'. On the CD-ROMs are full distributions of X11R6.3,, - Emacs, GCC, and current versions of all other GNU Software. *Note GNU - Software::, for more about these packages. - - * New/Updated Manuals since Last Bulletin (*note Documentation::.) - - Since the last bulletin, we have published several updated editions of - our manuals (note the price changes): `GNU Emacs Manual', revised for - GNU Emacs version 20, now $30; & `Texinfo Manual', for version 3.11 of - Texinfo, now $25. We hope to have the following available very soon: - `GNU Tar manual', first time in print, freshly reorganized and - rewritten, $20; `GNU Software for MS-Windows and MS-DOS', a book and - CD-ROM set with a variety of GNU software compiled for MS-DOS and - Windows 3.1/95/97/NT, $35 ($140 for corporate orders). Watch our Web - site, `http://www.gnu.ai.mit.edu', for announcements of these - publications. - - * Fonts freed - - A free commercial-quality set of the basic 35 Postscript Type 1 fonts is - now finally available. The copyright holder of these fonts, URW++ - Design and Development Incorporated, has decided to release them under - the GPL. Each font includes `.pfb' (outlines), `.afm' (metrics), and - `.pfm' (Windows printer metrics) files. The fonts are compatible with - Adobe Type Manager and with general Type 1 manipulation tools, as well - as with Ghostscript and other Postscript language interpreters. - - The fonts are available in `ghostscript-fonts-4.0.tar.gz' on the usual - FTP sites. - - * DDD now works with LessTif (Also *note GNU Software::.) Release 2.1.1 - of DDD, the Data Display Debugger, now works with LessTif, a free Motif - clone. - - * Give to GNU the United Way! - - As a 501(c)3 tax-exempt organization, the FSF is eligible to receive - United Way funds. When donating to United Way, one can specify that all - or part of the donation be directed to the FSF. On the donor form, - check the "Specific Requests" box and include the sentence, "Send my - gift to the Free Software Foundation, 59 Temple Place, Suite 330, - Boston, MA 02111." We especially appreciate the donations from Microsoft - matching the United Way donations of their employees. Also see *Note - Donations Translate Into Free Software::, and *Note Cygnus Matches - Donations!::. - - * Tapes and MS-DOS Diskettes No Longer Available from the FSF - - We no longer offer tapes or MS-DOS diskettes due to very low demand. - - * GNU Software Works on MS-DOS (Also *note GNU Software::.) - - GNU Emacs 19 and many other GNU programs have been ported to MS-DOS for - i386/i486/Pentium machines. We ship binaries & sources on the *Note - Compiler Tools Binaries CD-ROM::. - - * The FSF Takes Discover - - The Free Software Foundation now accepts the Discover card for orders or - donations. We also accept the following: Carte Blanche, Diner's Club, - JCB, MasterCard, Visa, and American Express.

This code has been merged into - Emacs and is included in Emacs 20. - - * GPC, the GNU Pascal Compiler - - The GNU Pascal Compiler (GPC) is part of the GNU compiler family, GNU CC - or GCC. It combines a Pascal front end with the proven GNU compiler - backend for code generation and optimization. Unlike utilities such as - p2c, this is a true compiler, not just a converter. - - Version 2.0 of GPC corresponds to GCC version 2.7.2.1. - - The purpose of the GNU Pascal project is to produce a compiler which: - * combines the clarity of Pascal with powerful tools suitable for - real-life programming, - - * supports both the Pascal standard and the Extended Pascal standard - as defined by ISO, ANSI and IEEE. (ISO 7185:1990, ISO/IEC - 10206:1991, ANSI/IEEE 770X3.160-1989) - - * supports other Pascal standards (UCSD Pascal, Borland Pascal, - Pascal-SC) in so far as this serves the goal of clarity and - usability, - - * can generate code for and run on any computer for which the GNU C - Compiler can generate code and run on. - - The current release (2.0) implements Standard Pascal (ISO 7185, level 0) - and a large subset of Extended Pascal (ISO 10206) and Borland Pascal. - - The upcoming release 2.1 features better conformance to the various - Pascal standards, and of course bug fixes. - - A growing group of GPC enthusiasts contributes to the project with code, - bug reports or fixes. - - `http://agnes.dida.physik.uni-essen.de/~gnu-pascal/', also known as - `http://home.pages.de/~gnu-pascal/', is the GNU Pascal home page; - sources may be downloaded from `ftp://kampi.hut.fi/jtv/gnu-pascal/' - (official) or `ftp://agnes.dida.physik.uni-essen.de/pub/gnu-pascal/' - (development versions). - - * GUILE - - GUILE 1.2 is released. GNU's Ubiquitous Intelligent Language for - Extension is an SCM-based library that can make any ordinary C program - extensible. (For SCM info, see "JACAL" in *Note GNU Software::.) - Nightly snapshots of the development sources are also available, in - `ftp://ftp.red-bean.com/pub/guile/guile-core-snap.tar.gz'. - - Also being developed are SCSH-compatible system call & Tk interfaces, a - module system, dynamic linking support, & a byte-code interpreter. - Support for Emacs Lisp & a more C-like language is coming. - - * A New FSF T-shirt! - - We have a new T-shirt design. *Note FSF T-shirt::, for the description. - - * New free game - - In August 1995, the action game Abuse by Jonathan Clark was released for - the first time. It wasn't free software then--but now, less than two - years later, the company Crack dot Com has rereleased it as free - software. Abuse was initially developed on Linux-based GNU systems, and - we've included it on our our source CD set. - - Beyond providing the free software community with a game that many - people enjoy, and code that could be useful for developing other free - games, this demonstrates an important fact about the economic - circumstances of computer game development: most non-free games bring - their profit in a very short period of time. Therefore, a game company - can turn a game into free software fairly soon, with little hardship. - - Let's hope that other game developers follow this example. - - - -The Deluxe Distribution -*********************** - -The Free Software Foundation has been asked repeatedly to create a package -that provides executables for all of our software. Normally we offer only -sources. The Deluxe Distribution provides binaries with the source code and -includes six T-shirts, all our CD-ROMs, printed manuals, & reference cards. - -The FSF Deluxe Distribution contains the binaries and sources to hundreds of -different programs including Emacs, the GNU C/C++ Compiler, the GNU Debugger, -the complete X Window System, and all the GNU utilities. - -We will make a Deluxe Distribution for most machines/operating systems. We -may be able to send someone to your office to do the compilation, if we can't -find a suitable machine here. However, we can only compile the programs that -already support your chosen machine/system - porting is a separate matter. -(To commission a port, see the GNU Service Directory; details in *Note Free -Software Support::.) Compiling all these programs takes time; a Deluxe -Distribution for an unusual machine will take longer to produce than one for -a common machine. Please contact the FSF Office with any questions. - -We supply the software on a write-once CD-ROM (in ISO 9660 format with "Rock -Ridge" extensions), or on one of these tapes in Unix `tar' format: 1600 or -6250bpi 1/2in reel, Sun DC300XLP 1/4in cartridge - QIC24, IBM RS/6000 1/4in -c.t. - QIC 150, Exabyte 8mm c.t., or DAT 4mm c.t. If your computer cannot -read any of these, please contact us to see if we can handle your format. - -The manuals included are one each of `Bison', `Calc', `GAWK', `GCC', `GNU C -Library', `GDB', `Flex', `GNU Emacs Lisp Reference', `Programming in Emacs -Lisp: An Introduction', `Make', `Texinfo', & `Termcap' manuals; six copies of -the `GNU Emacs' manual; and ten reference cards each for Emacs, Bison, Calc, -Flex, & GDB. - -Every Deluxe Distribution also has a copy of the latest editions of our -CD-ROMs that have sources of our software & compiler tool binaries for some -systems. The CDs are in ISO 9660 format with Rock Ridge extensions. - -The price of the Deluxe Distribution is $5000 (shipping included). These -sales provide enormous financial assistance to help the FSF develop more free -software. To order, please fill out the "Deluxe Distribution" section on the -*note Free Software Foundation Order Form::. and send it to: - - Free Software Foundation, Inc. - 59 Temple Place - Suite 330 - Boston, MA 02111-1307 - USA - - Telephone: +1-617-542-5942 - Fax (including Japan): +1-617-542-2652 - Electronic Mail: gnu@prep.ai.mit.edu - World Wide Web: http://www.gnu.ai.mit.edu - - - -GNU Documentation -***************** - -GNU is dedicated to having quality, easy-to-use online & printed -documentation. GNU manuals are intended to explain underlying concepts, -describe how to use all the features of each program, & give examples of -command use. GNU manuals are distributed as Texinfo source files, which -yield both typeset hardcopy via the TeX document formatting system and online -hypertext display via the menu-driven Info system. Source for these manuals -comes with our software; here are the manuals that we publish as printed -books. *Note Free Software Foundation Order Form::, to order them. - -Most GNU manuals are bound as soft cover books with "lay-flat" bindings. -This allows you to open them so they lie flat on a table without creasing the -binding. They have an inner cloth spine and an outer cardboard cover that -will not break or crease as an ordinary paperback will. Currently, the -`Using and Porting GNU CC', `GDB', `Emacs', `Emacs Lisp Reference', -`Programming in Emacs Lisp: An Introduction', `GNU Awk User's Guide', `Make', -& `Bison' manuals have this binding. Our other manuals also lie flat when -opened, using a GBC binding. Our manuals are 7in by 9.25in except the 8.5in -by 11in `Calc' manual. - -The edition number of the manual and version number of the program listed -after each manual's name were current at the time this Bulletin was published. - -`Debugging with GDB' (for Version 4.16) tells how to run your program under -GNU Debugger control, examine and alter data, modify a program's flow of -control, and use GDB through GNU Emacs. - -The `GNU Emacs Manual' (13th Edition for Version 20) describes editing with -GNU Emacs. It explains advanced features, including international character -sets; outline mode and regular expression search; how to use special -programming modes to write languages like C++ and TeX; how to use the `tags' -utility; how to compile and correct code; how to make your own keybindings; -and other elementary customizations. - -`Programming in Emacs Lisp: An Introduction' (October 1995 Edition 1.04) is -for people who are not necessarily interested in programming, but who do want -to customize or extend their computing environment. If you read it in Emacs -under Info mode, you can run the sample programs directly. - -`The GNU Emacs Lisp Reference Manual' (Edition 2.4 for Version 19.29) and -`The GNU Emacs Lisp Reference, Japanese Edition' (Japanese Draft Revision -1.0, from English Edition 2.4 for Version 19.29) cover this programming -language in depth, including data types, control structures, functions, -macros, syntax tables, searching/matching, modes, windows, keymaps, byte -compilation, and the operating system interface. - -`The GNU Awk User's Guide' (Edition 1.0 for Version 3.0) tells how to use -`gawk'. It is written for those who have never used `awk' and describes -features of this powerful string and record manipulation language. It -clearly delineates those features which are part of POSIX `awk' from `gawk' -extensions, providing a comprehensive guide to `awk' program portability. - -`GNU Make' (Edition 0.51 for Version 3.76 Beta) describes GNU `make', a -program used to rebuild parts of other programs. The manual tells how to -write "makefiles", which specify how a program is to be compiled and how its -files depend on each other. Included are an introductory chapter for novice -users and a section about automatically generated dependencies. - -The `Flex' manual (Edition 1.03 for Version 2.3.7) teaches you to write a -lexical scanner definition for the `flex' program to create a C++ or C-coded -scanner that recognizes the patterns defined. You need no prior knowledge of -scanners. - -`The Bison Manual' (November 1995 Edition for Version 1.25) teaches you how -to write context-free grammars for the Bison program that convert into -C-coded parsers. You need no prior knowledge of parser generators. - -`Using and Porting GNU CC' (November 1995 Edition for Version 2.7.2) tells -how to run, install, and port the GNU C Compiler to new systems. It lists -new features and incompatibilities of GCC, but people not familiar with C -will still need a good reference on the C programming language. It also -covers G++. - -The `Texinfo' manual (Edition 2.24 for Version 3) explains the markup -language that produces our online Info documentation & typeset hardcopies. -It tells you how to make tables, lists, chapters, nodes, accented & special -characters, indexes, cross references, & how to catch mistakes. - -`The Termcap Manual' (3rd Edition for Version 1.3), often described as "twice -as much as you ever wanted to know about termcap," details the format of the -termcap database, the definitions of terminal capabilities, and the process -of interrogating a terminal description. This manual is primarily for -programmers. - -The `C Library Reference Manual' (Edition 0.08 for Version 2.0) describes the -library's facilities, including both what Unix calls "library functions" & -"system calls." We are doing small copier runs of this manual until it -becomes more stable. Please send fixes to `bug-glibc-manual@prep.ai.mit.edu'. - -The `Emacs Calc Manual' (for Version 2.02) is both a tutorial and a reference -manual. It tells how to do ordinary arithmetic, how to use Calc for algebra, -calculus, and other forms of mathematics, and how to extend Calc. - - - -GNU Software -************ - -All our software is available via FTP; see *Note How to Get GNU Software::. -We also offer *Note CD-ROMs::, and printed *Note Documentation::, which -includes manuals and reference cards. In the articles describing the -contents of each medium, the version number listed after each program name -was current when we published this Bulletin. When you order a newer CD-ROM, -some of the programs may be newer and therefore the version number higher. -*Note Free Software Foundation Order Form::, for ordering information. - -Some of the contents of our FTP distributions are compressed. We have -software on our FTP sites to uncompress these files. Due to patent troubles -with `compress', we use another compression program, `gzip'. - -You may need to build GNU `make' before you build our other software. Some -vendors supply no `make' utility at all and some native `make' programs lack -the `VPATH' feature essential for using the GNU configure system to its full -extent. The GNU `make' sources have a shell script to build `make' itself on -such systems. - -We welcome all bug reports and enhancements sent to the appropriate -electronic mailing list (*note Free Software Support::.). - - - -Configuring GNU Software ------------------------- - -We are using Autoconf, a uniform scheme for configuring GNU software packages -in order to compile them (see "Autoconf" and "Automake" below, in this -article). The goal is to have all GNU software support the same alternatives -for naming machine and system types. - -Ultimately, it will be possible to configure and build the entire system all -at once, eliminating the need to configure each individual package separately. - -You can also specify both the host and target system to build -cross-compilation tools. Most GNU programs now use Autoconf-generated -configure scripts. - - - -GNU Software Now Available --------------------------- - -For future programs and features, see *Note Forthcoming GNUs::. - -Key to cross reference: - - BinCD January 1997 Binaries CD-ROM - SrcCD July 1997 Source CD-ROMs - -[FSFman] shows that we sell a manual for that package. [FSFrc] shows we sell -a reference card for that package. To order them, *Note Free Software -Foundation Order Form::. *Note Documentation::, for more information on the -manuals. Source code for each manual or reference card is included with each -package. - - * `abuse' *Also *note GNUs Flashes::.* (SrcCD) - - The recently-freed program `abuse' is a dark, side-scrolling game with - Robotron-esque controls: you control your movement with the keyboard and - fire & aim with the mouse. You can get more info at - `http://crack.com/games/abuse'. - - * acct (SrcCD) - - acct is a system accounting package. It includes the programs `ac' - (summariize login accounting), `accton' (turn accounting on or off), - `last' (show who has logged in recently), `lastcomm' (show which - commands have been used), `sa' (summarize process accounting), - `dump-utmp' (print a `utmp' file in human-readable format), & - `dump-acct' (print an `acct' or `pacct' file in human-readable format). - - * `acm' (SrcCD) - - `acm' is a LAN-oriented, multiplayer, aerial combat simulation that runs - under the X Window System. Players engage in air to air combat against - one another using heat seeking missiles and cannons. We are working on - a more accurate simulation of real airplane flight characteristics. - - * aegis (SrcCD) - - Aegis is a transaction-based software configuration management system. - It provides a framework within which a team of developers may work on - many changes to a program concurrently, and Aegis coordinates - integrating these changes back into the master source of the program, - with as little disruption as possible. - - * Apache *Also see* `http://www.apache.org/' (SrcCD) - - Apache is an HTTP server designed as a successor to the NCSA family of - Web servers. It adds a significant amount of new functionality, has an - extensive API for modular enhancements, is extremely flexible without - compromising speed, and has an active development group and user - community. - - * Autoconf (SrcCD) - - Autoconf produces shell scripts which automatically configure source code - packages. These scripts adapt the packages to many kinds of Unix-like - systems without manual user intervention. Autoconf creates a script for - a package from a template file which lists the operating system features - which the package can use, in the form of `m4' macro calls. Autoconf - requires GNU `m4' to operate, but the resulting configure scripts it - generates do not. - - * Automake (SrcCD) - - Automake is a tool for generating `Makefile.in' files for use with - Autoconf. The generated makefiles are compliant with GNU Makefile - standards. - - * BASH (SrcCD) - - GNU's shell, BASH (Bourne Again SHell), is compatible with the Unix `sh' - and offers many extensions found in `csh' and `ksh'. BASH has job - control, `csh'-style command history, command-line editing (with Emacs - and `vi' modes built-in), and the ability to rebind keys via the - `readline' library. BASH conforms to the POSIX 1003.2-1992 standard. - - * bc (SrcCD) - - `bc' is an interactive algebraic language with arbitrary precision - numbers. GNU `bc' follows the POSIX 1003.2-1992 standard with several - extensions, including multi-character variable names, an `else' - statement, and full Boolean expressions. The RPN calculator `dc' is now - distributed as part of the same package, but GNU `bc' is not implemented - as a `dc' preprocessor. - - * BFD (BinCD, SrcCD) - - The Binary File Descriptor library allows a program which operates on - object files (e.g., `ld' or GDB) to support many different formats in a - clean way. BFD provides a portable interface, so that only BFD needs to - know the details of a particular format. One result is that all - programs using BFD will support formats such as a.out, COFF, and ELF. - BFD comes with Texinfo source for a manual (not yet published on paper). - - At present, BFD is not distributed separately; it is included with - packages that use it. - - * Binutils (BinCD, SrcCD) - - Binutils includes these programs: `addr2line', `ar', `c++filt', `gas', - `gprof', `ld', `nm', `objcopy', `objdump', `ranlib', `size', `strings', & - `strip'. - - Binutils version 2 uses the BFD library. The GNU assembler, `gas', - supports the a29k, Alpha, ARM, D10V, H8/300, H8/500, HP-PA, i386, i960, - M32R, m68k, m88k, MIPS, Matsushita 10200 and 10300, NS32K, PowerPC, - RS/6000, SH, SPARC, Tahoe, Vax, and Z8000 CPUs, and attempts to be - compatible with many other assemblers for Unix and embedded systems. It - can produce mixed C and assembly listings, and includes a macro facility - similar to that in some other assemblers. GNU's linker, `ld', supports - shared libraries on many systems, emits source-line numbered error - messages for multiply-defined symbols and undefined references, and - interprets a superset of AT&T's Linker Command Language, which gives - control over where segments are placed in memory. `objdump' can - disassemble code for most of the CPUs listed above, and can display - other data (e.g., symbols and relocations) from any file format read by - BFD. - - * Bison (BinCD, SrcCD) [FSFman, FSFrc] - - Bison is an upwardly compatible replacement for the parser generator - `yacc'. Texinfo source for the `Bison Manual' and reference card are - included. - - * C Library (`glibc') (BinCD, SrcCD) [FSFman] - - The GNU C library supports ISO C-1989, ISO C/amendment 1-1995, POSIX - 1003.1-1990, POSIX 1003.1b-1993, POSIX 1003.1c-1995 (when the underlying - system permits), & most of the functions in POSIX 1003.2-1992. It is - nearly compliant with the extended XPG4.2 specification which guarantees - upward compatibility with 4.4BSD & many System V functions. - - When used with the GNU Hurd, the C Library performs many functions of the - Unix system calls directly. Mike Haertel has written a fast `malloc' - which wastes less memory than the old GNU version. - - GNU `stdio' lets you define new kinds of streams, just by writing a few - C functions. Two methods for handling translated messages help writing - internationalized programs & the user can adopt the environment the - program runs in to conform with local conventions. Extended `getopt' - functions are already used to parse options, including long options, in - many GNU utilities. The name lookup functions now are modularized which - makes it easier to select the service which is needed for the specific - database & the document interface makes it easy to add new services. - Texinfo source for the `GNU C Library Reference Manual' is included - (*note Documentation::.). - - Previous versions of the GNU C library ran on a large number of systems. - The architecture-dependent parts of the C library have not been updated - since development on version 2.0 started, so today it runs out of the - box only on GNU/Hurd (all platforms GNU/Hurd also runs on) & GNU/Linux - (ix86, Alpha, m68k, MIPS, Sparc, PowerPC; work is in progress for ARM). - Other architectures will become available again as soon as somebody does - the port. - - * C++ Library (`libg++') (BinCD, SrcCD) - - The GNU C++ library (traditionally called `libg++') includes libstdc++, - which implements the library facilities defined by the forthcoming ISO - C++ standard. This includes strings, iostream, and various container - classes. All of this is templatized. - - The package also contains the older libg++ library for backward - compatibility, but new programs should avoid using it. - - * Calc (SrcCD) [FSFman, FSFrc] - - Calc (written by Dave Gillespie in Emacs Lisp) is an extensible, advanced - desk calculator & mathematical tool that runs as part of GNU Emacs. You - can use Calc as a simple four-function calculator, but it has many more - features including: choice of algebraic or RPN (stack-based) entry; - logarithmic, trigonometric, & financial functions; arbitrary precision; - complex numbers; vectors; matrices; dates; times; infinities; sets; - algebraic simplification; & differentiation & integration. It outputs - to `gnuplot', & comes with source for a manual & reference card (*note - Documentation::.). - - * `cfengine' (SrcCD) - - `cfengine' is used to maintain site-wide configuration of a - heterogeneous Unix network using a simple high level language. Its - appearance is similar to `rdist', but allows many more operations to be - performed automatically. See Mark Burgess, "A Site Configuration - Engine", `Computing Systems', Vol. 8, No. 3 (ask `office@usenix.org' how - to get a copy). - - * Chess (SrcCD) - - GNU Chess enables you to play a game of chess with a computer instead of - a person. It is useful to practice with when there are significant - spare cpu cycles and a real person is unavailable. - - The program offers a plain terminal interface, one using curses, and a - reasonable X Windows interface `xboard'. Best results are obtained by - compiling with GNU C. - - Improvements this past year are in the Windows-compatible version, - mostly bugfixes. - - Stuart Cracraft started the GNU mascot back in the mid-1980's. John - Stanback (and innumerable contributors) are responsible for GNU's brain - development and its fair play. Acknowledgements for the past year's - work are due Conor McCarthy. - - Send bugs to `bug-gnu-chess@prep.ai.mit.edu' & general comments to - `info-gnu-chess@prep.ai.mit.edu'. Visit the author's Web site at - `http://www.earthlink.net/~cracraft/index.html'. Play GNU Chess on the - Web at `http://www.delorie.com/game-room/chess'. - - * CLISP (SrcCD) - - CLISP is a Common Lisp implementation by Bruno Haible & Michael Stoll. - It mostly supports the Lisp described by `Common LISP: The Language (2nd - edition)' & the ANSI Common Lisp standard. CLISP includes an - interpreter, a byte-compiler, a large subset of CLOS & a foreign language - interface. The user interface language (English, German, French) can be - chosen at run time. An X11 API is available through CLX & Garnet. - CLISP needs only 2 MB of memory & runs on all kinds of Unix systems & on - many microcomputers (including MS-DOS systems, OS/2, Windows NT, Windows - 95, Amiga 500-4000, & Acorn RISC PC). See also item "Common Lisp", - which describes GCL, a complete Common Lisp implementation with compiler. - - * CLX (SrcCD) - - CLX is an X Window interface library for GCL. This is separate from the - built-in TK interface. - - * Common Lisp (`gcl') (SrcCD) - - GNU Common Lisp (GCL, formerly known as Kyoto Common Lisp) is a compiler - & interpreter for Common Lisp. GCL is very portable & extremely - efficient on a wide class of applications, & compares favorably in - performance with commercial Lisps on several large theorem-prover & - symbolic algebra systems. GCL supports the CLtL1 specification but is - moving towards the proposed ANSI standard. - - GCL compiles to C & then uses the native optimizing C compiler (e.g., - GCC). A function with a fixed number of args & one value turns into a C - function of the same number of args, returning one value--so GCL is - maximally efficient on such calls. Its conservative garbage collector - gives great freedom to the C compiler to put Lisp values in registers. - It has a source level Lisp debugger for interpreted code & displays - source code in an Emacs window. Its profiler (based on the C profiling - tools) counts function calls & the time spent in each function. - - There is now a built-in interface to the Tk widget system. It runs in a - separate process, so users may monitor progress on Lisp computations or - interact with running computations via a windowing interface. - - There is also an Xlib interface via C (xgcl-2). CLX runs with GCL, as - does PCL (see "PCL" later in this article). - - GCL version 2.2.2 is released under the GNU Library General Public - License. - - * cook (SrcCD) - - Cook is a tool for constructing files, and maintaining referential - integrity between files. It is given a set of files to create, and - recipes of how to create and maintain them. In any non-trivial program - there will be prerequisites to performing the actions necessary to - creating any file, such as include files. The `cook' program provides a - mechanism to define these. - - Some features which distinguish Cook include a strong procedural - description language, and fingerprints to supplement file modification - time stamps. There is also a `make2cook' utility included to ease - transition. - - * `cpio' (SrcCD) - - `cpio' is an archive program with all the features of SVR4 `cpio', - including support for the final POSIX 1003.1 `ustar' standard. `mt', a - program to position magnetic tapes, is included with `cpio'. - - * CVS (SrcCD) - - CVS is a version control system (like RCS or SCCS) which allows you to - keep old versions of files (usually source code), keep a log of who, - when, and why changes occurred, etc. It handles multiple developers, - multiple directories, triggers to enable/log/control various operations, - and can work over a wide area network. It does not handle build - management or bug-tracking; these are handled by `make' and GNATS, - respectively. - - * `cxref' (SrcCD) - - `cxref' is a program that will produce documentation (in LaTeX or HTML) - including cross-references from C program source code. It has been - designed to work with ANSI C, incorporating K&R, and most popular GNU - extensions. The documentation for the subject program is produced from - comments in the code that are appropriately formatted. The cross - referencing comes from the code itself and requires no extra work. - - * DDD (SrcCD) - - The Data Display Debugger (DDD) is a common graphical user interface to - GDB, DBX, and XDB, the popular Unix debuggers. DDD provides a graphical - data display where complex data structures can be explored incrementally - and interactively. DDD has been designed to compete with well-known - commercial debuggers; as of release 2.1.1, DDD also compiles and runs - with LessTif, a free Motif clone, without loss of functionality. For - more details, see the DDD WWW page at - `http://www.cs.tu-bs.de/softech/ddd/'. - - * DejaGnu (SrcCD) - - DejaGnu is a framework to test programs with a single front end for all - tests. DejaGnu's flexibility & consistency makes it easy to write tests. - DejaGnu will also work with remote hosts and embedded systems. - - DejaGnu comes with `expect', which runs scripts to conduct dialogs with - programs. - - * Diffutils (SrcCD) - - GNU `diff' compares files showing line-by-line changes in several - flexible formats. It is much faster than traditional Unix versions. The - Diffutils package has `diff', `diff3', `sdiff', & `cmp'. Future plans - include support for internationalization (e.g., error messages in - Chinese) & some non-Unix PC environments, & a library interface that can - be used by other free software. - - * DJGPP *Also see "GCC" below* (BinCD) - - DJ Delorie has ported GCC/G++ to i386s running DOS. DJGPP has a 32-bit - i386 DOS extender with a symbolic debugger, development libraries, & - ports of Bison, `flex', & Binutils. Full source code is provided. It - needs at least 5MB of hard disk space to install & 512K of RAM to use. - It supports SVGA (up to 1024x768), XMS & VDISK memory allocation, - `himem.sys', VCPI (e.g., QEMM, DESQview, & 386MAX), & DPMI (e.g., - Windows 3.x, OS/2, QEMM, & QDPMI). Version 2 was released in Feb. 1996, - & needs a DPMI environment; a free DPMI server is included. - - WWW at `http://www.delorie.com/djgpp/' or FTP from `ftp.simtel.net' in - `/pub/simtelnet/gnu/djgpp/' (or a SimTel mirror site). - - Ask `listserv@delorie.com', to join a DJGPP users mailing list. - - * `dld' (SrcCD) - - `dld' is a dynamic linker written by W. Wilson Ho. Linking your program - with the `dld' library allows you to dynamically load object files into - the running binary. `dld' supports a.out object types on the following - platforms: Convex C-Series (BSD), i386/i486/Pentium (GNU/Linux), Sequent - Symmetry i386 (Dynix 3), Sun-3 (SunOS 3 & 4), Sun-4 (SunOS 4), & VAX - (Ultrix). - - * `doschk' (SrcCD) - - This program is a utility to help software developers ensure that their - source file names are distinguishable on System V platforms with - 14-character filenames and on MS-DOS systems with 8+3 character - filenames. - - * `ed' (SrcCD) - - `ed' is the standard text editor. It is line-oriented and can be used - interactively or in scripts. - - * Elib (SrcCD) - - Elib is a small library of Emacs Lisp functions, including routines for - using AVL trees and doubly-linked lists. - - * Elisp archive (SrcCD) - - This is a snapshot of Ohio State's GNU Emacs Lisp FTP Archive. FTP it - from `archive.cis.ohio-state.edu' in `/pub/gnu/emacs/elisp-archive'. - - * Emacs *Also *note GNUs Flashes::.* [FSFman(s), FSFrc] - - In 1975, Richard Stallman developed the first Emacs, an extensible, - customizable real-time display editor & computing environment. GNU Emacs - is his second implementation. It offers true Lisp--smoothly integrated - into the editor--for writing extensions & provides an interface to the X - Window System. It runs on Unix, MS-DOS, & Windows NT or 95. In - addition to its powerful native command set, Emacs can emulate the - editors vi & EDT (DEC's VMS editor). Emacs has many other features which - make it a full computing support environment. Source for the `GNU Emacs - Manual' & a reference card comes with the software. Sources for the - `GNU Emacs Lisp Reference Manual', & `Programming in Emacs Lisp: An - Introduction' are distributed in separate packages. *Note - Documentation::. - - * Emacs 20 (SrcCD) [FSFman(s), FSFrc] - - Emacs 20.1 was just released recently. Its main new features include - support for many languages and many character codes (the MULE facility) - and a new convenient customization feature. The text-filling commands - handle indented and bulleted paragraphs conveniently; there are new help - facilities for looking up documentation about functions and symbols in - various languages. A new method of file-locking works even when using - NFS. Some dired commands have been made more systematic. - - We believe Emacs 20 operates on the same systems as Emacs 19, but we do - not have confirmation for all of them. - - * Emacs 19 (SrcCD) [FSFman(s), FSFrc] - - Emacs 19 works with character-only terminals & with the X Window System - (with or without an X toolkit).

- - - - - -CD-ROMs -******* - -We have two series of CD-ROMs: the Source Code CD-ROM, and the Compiler -Tools Binaries CD-ROM. - -Our CDs are in ISO 9660 format & can be mounted as a read-only file system on -most computers. If your driver supports it, you can mount each CD with "Rock -Ridge" extensions & it will look like a regular Unix file system, rather than -one full of truncated & otherwise mangled names that fit vanilla ISO 9660. - -You can build most of the software without copying the sources off the CD. -You only need enough disk space for object files and intermediate build -targets. - - - -Pricing of the GNU CD-ROMs --------------------------- - -If a business or organization is ultimately paying, the current GNU Source -CD set costs $240. The set costs $60 if you, an individual, are paying out -of your own pocket. The current Compiler Tools Binaries CD-ROM costs $220 -for a business or organization, and $55 for an individual. - - - -What Do the Different Prices Mean? -.................................. - -The software on our disks is free; anyone can copy it and anyone can run it. -What we charge for is the physical disk and the service of distribution. - -We charge two different prices depending on who is buying. When a company -or other organization buys the Source CD-ROMs, we charge $240. When an -individual buys the same CD-ROMs, we charge just $60. This distinction is -not a matter of who is allowed to use the software. In either case, once -you have a copy, you can distribute as many copies as you wish and there's -no restriction on who can have or run them. The price distinction is -entirely a matter of what kind of entity pays for the CDs. - -You, the reader, are certainly an individual, not a company. If you are -buying a disk "in person", then you are probably doing so as an individual. -But if you expect to be reimbursed by your employer, then the disk is really -for the company; so please pay the company price and get reimbursed for it. -We won't try to check up on you--we use the honor system--so please cooperate. - -Buying CDs at the company price is very helpful for GNU; just -150 Source CDs at that price support an FSF programmer or tech writer for a -year. - - - -Why Is There an Individual Price? -................................. - -In the past, our distribution tapes were ordered mainly by companies. The CD -at the price of $240 provides them with all of our software for a much lower -price than they would previously have paid for six different tapes. To lower -the price more would cut into the FSF's funds very badly and decrease the -software development we can do. - -However, for individuals, $240 is too high a price; hardly anyone could -afford that. So we decided to make CDs available to individuals at the lower -price of $60. - - - -Is There a Maximum Price? -......................... - -Our stated prices are minimum prices. Feel free to pay a higher price if you -wish to support GNU development more. The sky's the limit; we will accept as -high a price as you can offer. Or simply give a donation (tax-deductible in -the U.S.) to the Free Software Foundation, a tax-exempt public charity. - - - -January 1997 Compiler Tools Binaries CD-ROM -------------------------------------------- - -In January 1997 we released the fourth edition of our CD-ROM that has -binaries and complete sources for GNU compiler tools for some systems which -lack a compiler. This enables the people who use these systems to compile -GNU and other free software without having to buy a proprietary compiler. -You can also use these GNU tools to compile your own C/C++/Objective-C -programs. Older editions of this CD are available while supplies last at a -reduced price; *Note Free Software Foundation Order Form::. - -We hope to have more systems on each update of this CD. If you can help -build binaries for new systems (especially those that don't come with a C -compiler), or have one to suggest, please contact us at the addresses on page -1. - -These packages: - - * DJGPP - * GCC/G++/Objective-C - * GNU C Library - * GDB - * Binutils - * Bison - * Emacs (MS-DOS only) - * Flex - * Make - * libg++ - -On these platforms: - - * `i386-msdos' - * `hppa1.1-hp-hpux9' - * `hppa1.1-hp-hpux10' - * `powerpc-ibm-aix4.2' - * `sparc-sun-solaris2.4' - * `sparc-sun-solaris2.5' - * `sparc-sun-sunos4.1' - - - -Source Code CD-ROMs -------------------- - -We have several versions of our Source Code CD-ROMs available, including: - - * July 1997 Source Code CD-ROMs, the newest release, has programs, - bug fixes, & improvements. See below. - - * January 1997 Source Code CD-ROMs. - - * July 1996 Source Code CD-ROMss. - - * December 1995 Source Code CD-ROMs. - - * June 1995 Source Code CD-ROM. - - * May 1994 Source Code CD-ROM. - - * November 1993 Source Code CD-ROM. - - * May 1993 Source Code CD-ROM. - - * October 1992 Source Code CD-ROM. - -The older Source CDs are available while supplies last at a reduced price -(please note that the December 1994 Source CD is permanently out of stock). -All the Source CDs have Texinfo source for the GNU manuals listed in *Note -Documentation::. - -Much of X11 is *not* on the older Source CDs which are just one CD -instead of two. - -There are no precompiled programs on these Source CDs. You will need a C -compiler (programs which need some other interpreter or compiler normally -provide the C source for a bootstrapping program).
