-GREP DJGPP README

-=================

-

-To compile the GNU grep package with DJGPP tools, you will need the

-following tools (the names of the archives on DJGPP ftp sites where

-these tools are available are in parentheses):

-

-          -  The basic DJGPP development environment, including the

-             GCC compiler and the libraries (v2gnu/gccNNNb.zip,

-             v2gnu/bnuNNNb.zip, v2/djdevNNN.zip).

-

-          -  GNU Make revision 3.75 or later (v2gnu/makNNNb.zip).

-

-          -  GNU Bash (v2gnu/bshNNNb.zip).

-

-          -  GNU Sed (v2gnu/sedNNNb.zip).

-

-          -  GNU M4 (v2gnu/m4-NNNb.zip).

-

-          -  GNU Fileutils (v2gnu/filNNNb.zip), Textutils

-             (v2gnu/txtNNNb.zip) and Diffutils (v2gnu/difNNNb.zip).

-

-          -  A (previous version of) GNU grep (v2gnu/grepNNb.zip).

-

-Running the tests ("make check" in the top-level directory)

-additionally requires Gawk (v2gnu/gwkNNNb.zip).  TAGS and ID targets

-require `etags' (from the Emacs distribution) and `mkid' (from

-ID-utils, v2gnu/iduNNb.zip), respectively.

-

-All of these tools are available from the DJGPP archive sites.

-

-To build grep:

-          sh autogen.sh

-      sh configure

-          make

-

-

-Source distributions on DJGPP sites usually come pre-configured, so

-all you need to do in order to build the programs is to say "make".

-However, source distributions on GNU ftp sites, like ftp.gnu.org,

-need to be configured by running sh configure.  You will also need

-to run it if you need to configure grep differently than for the

-default configuration, for example if you want to install the programs

-in a directory other than the bin subdirectory of your DJGPP

-installation.

-

-To test that the package works, say "make check".  If you don't have a

-file named sh.exe somewhere on your PATH, "make check" will refuse to

-run, as it needs a Unix-like shell.

-

-To install, either copy the executables and man pages to the

-appropriate directories, or say "make install".  To clean up, say

-"make clean" or "make distclean".

-

-Please note the -u and -U options that specifically target MS-DOS and

-MS-Windows environments.  They are described in the grep man page in

-this distribution.

-

-National Language Support doesn't work in this port, so don't expect

-the programs to talk to you in any language but English.

-

-Please post any problems in the DOS version to the comp.os.msdos.djgpp

-news group first, especially if they have something to do with the

-DOS-specific aspects.

-

-To create the files required for the documentation package

-perform the following in the docs directory:

-        make grep.dvi

-        make grep.ps

-        makeinfo --html grep.texi -o grep.html

-

-

-2.5f ported by Andrew Cottrell <anddjgpp@ihug.com.au>

-

-Enjoy,

-                                Eli Zaretskii <eliz@is.elta.co.il>
