This is a DOS/DJGPP port of Perl 5.004_5x

1. Installation
   ------------

   - Unzip the binary package perl54b.zip preserving the directory
     structure (-d switch to PKUNZIP) from the top DJGPP directory.
     If you want to use perl with long file names (win0.95), then use a LFN
     aware unzip and add

              set LFN=y

     to your autoexec.bat or DJGPP.ENV.

   - Edit lib/perl5/Config.pm, and replace every 'c:/djgpp' with your
     DJGPP root directory. This can be done with perl too:
   
              perl -i~ -pe "s!c:/djgpp!x:/djroot!i;" lib/perl5/Config.pm
                                       ^^^^^^^^^
                        Substitute this with your DJGPP root directory!

   - This version of perl searches its library files in '../lib/perl5/',
     which is relative to the path of perl.exe. If you don't like this,
     you can use the PERL5LIB environment variable to tell perl where 
     the library is. E.g:
     
              set PERL5LIB=c:/perl/lib
              
     Warning: if you set PERL5LIB and use tainting checks (-T command line 
     option), perl ignores PERL5LIB, so you must use the -I command line
     switch or the "use lib '...'"  construct. Or you can patch perl.exe :)

   - Perl works best with a unixy shell, so you may want to download and
     install bash (bshXXXXb.zip from the usual DJGPP sites). After installing
     it make the 'SHELL' environment variable point to your bash.exe.
     Finally create a `link' to your bash.exe in your %DJDIR%/bin directory:

              ln -s bash.exe sh.exe
     or
              stubify -g sh.exe
              stubedit sh.exe runfile=bash

   - The documentation is in lib/perl5/pod. You can read the .pod files
     with any editor, or you can use the `perldoc' utility. For more info:

              perl -S perldoc -h

     It tries to use less.exe or more.com, but you can set your pager with:
     
              SET PAGER=path_of_your_favourite_pager

2. Building Perl
   -------------

   - In addition to the standard DJGPP tools, you will need sed, gawk, grep,
     sh-utils, textutils, fileutils, bash, diffutils, make and findutils. :-)
     You can find them on the usual DJGPP sites. If you want to build perl
     under win0.95, then you MUST use fileutils 3.16+ (3.13 doesn't work).

   - Unzip the source package perl54s.zip preserving the directory
     structure (-d switch to PKUNZIP) from the top DJGPP directory.
     Under plain DOS, use the -o switch too when unzipping.
     This creates the directory gnu/perl5004.

   - Create a symlink or copy your bash.exe to sh.exe in your DJGPP/bin
     directory.

              ln -s bash.exe sh.exe

     And make the 'SHELL' environment variable point to this sh.exe:

              set SHELL=c:/djgpp/bin/sh.exe (use full path name!)

     You can do this in djgpp.env too. Add this line BEFORE any section
     definition:

              +SHELL=%DJDIR%/bin/sh.exe

   - If you have split.exe and gsplit.exe in your path, then rename split.exe
     to djsplit.exe, and gsplit.exe to split.exe.

   - Copy or link gecho.exe to echo.exe if you don't have echo.exe.

   - Copy or link gawk.exe to awk.exe if you don't have awk.exe.

   - Chdir to the gnu/perl5004/djgpp directory and type the following
     command:

              configure.bat

     This will do some preprocessing then run the Configure script.

     The Configure script is interactive, but in most of the cases you
     just need to press ENTER.

     If the script says that your package is incomplete, and ask whether
     to continue, just answer with Y (this can only happen if you don't use
     long filenames).

     When Configure asks about the extensions, I suggest IO and Fcntl,
     and if you want database handling then SDBM_File or GDBM_File
     (you need to install gdbm for this one). If you want to use the 
     POSIX extension (this is the default), make sure that the stack 
     size of your cc1.exe is at least 512kbyte (you can check this 
     with: stubedit cc1.exe).
     
        You can use the Configure script in non-interactive mode too. 
        When I've built my perl.exe, I used this:

                 configure.bat -Uuseposix -dEs

        then edited config.sh (set hostname & domainname), then

                 sh Configure -S

        You can find more info about Configure's command line switches in
        the `INSTALL' file.

   - When the script ends, and you want to change some values in the
     generated config.sh file, then run

              sh Configure -S

     after you made your modifications.

     IMPORTANT: if you use this -S switch, be sure to delete the CONFIG
     environment variable before running the script:

              set CONFIG=

   - Now you can compile Perl. Type:

              make

   - Run the tests:

              make test

     You should see "All tests successful" if you configured a database
     manager, and 1 failed test script if not (lib/anydbm.t). If you
     configured POSIX you will see 4 failed subtests in lib/posix.t.

   - If you want the documentation in HTML format, then read INSTALL in
     the main perl5004 source directory.

     WARNING: if you want to use absolute path names with `installhtml',
     use something like this:

             --htmldir=f:/html
             --htmlroot='/f|/html'     # "|" instead of ":" !!!

     or NETSCAPE does strange things.

   - If you don't want to use the modules, then you are ready: copy perl.exe
     into your bin directory.

   - Else install the files with:

              make install

 Enjoy.
