Look +for a command procedure name xxx-LIB.COM (in the library directories) +or MAKExxx.COM (in the program directories) and read the comments at +the top to understand how to use them. However, if you want to +compile all you can get, the simplest is to use MAKEVMS.COM in the top +directory. The syntax is trhe following: + + @MAKEVMS <option> <rsaref-p> <debug-p> [<compiler>] + +<option> must be one of the following: + + ALL Just build "everything". + DATE Just build the "[.INCLUDE]DATE.H" file. + SOFTLINKS Just copies some files, to simulate Unix soft links. + RSAREF Just build the "[.xxx.EXE.RSAREF]LIBRSAGLUE.OLB" library. + CRYPTO Just build the "[.xxx.EXE.CRYPTO]LIBCRYPTO.OLB" library. + SSL Just build the "[.xxx.EXE.SSL]LIBSSL.OLB" library. + SSL_TASK Just build the "[.xxx.EXE.SSL]SSL_TASK.EXE" program. + TEST Just build the "test" programs for OpenSSL. + APPS Just build the "application" programs for OpenSSL. + +<rsaref-p> must be one of the following: + + RSAREF compile using the RSAREF Library + NORSAREF compile without using RSAREF + +Note: The RSAREF libraries are NOT INCLUDED and you have to + download it from "ftp://ftp.rsa.com/rsaref". You have to + get the ".tar-Z" file as the ".zip" file dosen't have the + directory structure stored. You have to extract the file + into the [.RSAREF] directory as that is where the scripts + will look for the files. + +Note 2: I have never done this, so I've no idea if it works or not. + +<debug-p> must be one of the following: + + DEBUG compile with debugging info (will not optimize) + NODEBUG compile without debugging info (will optimize) + +<compiler> must be one of the following: + + VAXC For VAX C. + DECC For DEC C. + GNUC For GNU C. + + +You will find the crypto library in [.xxx.EXE.CRYPTO], called LIBCRYPTO.OLB, +where xxx is VAX or AXP. You will find the SSL library in [.xxx.EXE.SSL], +named LIBSSL.OLB, and you will find a bunch of useful programs in +[.xxx.EXE.APPS]. However, these shouldn't be used right off unless it's +just to test them. For production use, make sure you install first, see +Installation below. + +Note: Some programs in this package require a TCP/IP library. + +Note 2: if you want to compile the crypto library only, please make sure + you have at least done a @MAKEVMS DATE and a @MAKEVMS SOFTLINKS. + A lot of things will break if you don't. + +Test: +===== + +Testing is very simple, just do the following: + + @[.TEST]TESTS + +If a test fails, try with defining the logical name OPENSSL_NO_ASM (yes, +it's an ugly hack!) and rebuild. Please send a bug report to +<openssl-bugs@openssl.org>, including the output of "openssl version -a" +and of the failed test. + +Installation: +============= + +Installation is easy, just do the following: + + @INSTALL <root> + +<root> is the directory in which everything will be installed, +subdirectories, libraries, header files, programs and startup command +procedures. + +In the [.VMS] subdirectory of the installation, you will find the +following command procedures: + + OPENSSL_STARTUP.COM + + defines all needed logical names. Takes one argument that + tells it in what logical name table to insert the logical + names. If you insert if it SYS$MANAGER:SYSTARTUP_VMS.COM, the + call should look like this: + + @openssldev:[openssldir.VMS]OPENSSL_STARTUP "/SYSTEM" + + OPENSSL_UTILS.COM + + sets up the symbols to the applications. Should be called + from for example SYS$MANAGER:SYLOGIN.COM + +The logical names that are set up are the following: + + SSLROOT a dotted concealed logical name pointing at the + root directory. + SSLLIB points at the directory where CRYPTORTL.OLB and + SSLRTL.OLB are installed. + SSLINCLUDE points at the directory where the header files are + installed. + SSLEXE points at the directory where the applications are + installed. + SSLCERTS the place where the certificates are stored. + SSLPRIVATE I'm actually not sure what this is used for. + + +Backward portability: +===================== + +One great problem when you build a library is making sure it will work +on as many versions of VMS as possible. Especially, code compiled on +OpenVMS version 7.x and above tend to be unusable in version 6.x or +lower, because some C library routines have changed names internally +(the C programmer won't usually see it, because the old name is +maintained through C macros). One obvious solution is to make sure +you have a development machine with an old enough version of OpenVMS. +However, if you are stuck with a bunch of Alphas running OpenVMS version +7.1, you seem to be out of luck. Fortunately, the DEC C header files +are cluttered with conditionals that make some declarations and definitions +dependent on the OpenVMS version or the C library version, *and* you +can use those macros to simulate older OpenVMS or C library versions, +by defining the macros _VMS_V6_SOURCE, __VMS_VER and __CTRL_VER with +correct values. In the compilation scripts, I've provided the possibility +for the user to influense the creation of such macros, through a bunch of +symbols, all having names starting with USER_. Here's the list of them: + + USER_CCFLAGS - Used to give additional qualifiers to the + compiler. It can't be used to define macros + since the scripts will do such things as well. + To do such things, use USER_CCDEFS. + USER_CCDEFS - Used to define macros on the command line. The + value of this symbol will be inserted inside a + /DEFINE=(...). + USER_CCDISABLEWARNINGS - Used to disable some warnings. The value is + inserted inside a /DISABLE=WARNING=(...). + +So, to maintain backward compatibility with older VMS versions, do the +following before you start compiling: + + $ USER_CCDEFS := _VMS_V6_SOURCE=1,__VMS_VER=60000000,__CRTL_VER=60000000 + $ USER_CCDISABLEWARNINGS := PREOPTW + +The USER_CCDISABLEWARNINGS is there because otherwise, DEC C will complain +that those macros have been changed. + +Note: Currently, this is only usefull for library compilation. The + programs will still be linked with the current version of the + C library shareable image, and will thus complain if they are + faced with an older version of the same C library shareable image. + This will probably be fixed in a future revision of OpenSSL. + + +Possible bugs or quirks: +======================== + +I'm not perfectly sure all the programs will use the SSLCERTS: +directory by default, it may very well be that you have to give them +extra arguments. Please experiment. + + +Report: +======= + +I maintain a few mailinglists for bug reports and such on software that +I develop/port/enhance/destroy. Please look at http://www.free.lp.se/ +for further info. + + +-- +Richard Levitte <richard@levitte.org> +1999-03-09 |
