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.
