-This is a DOS/DJGPP port of Perl 5.004_5x
+If you read this file _as_is_, just ignore the funny characters you
+see. It is written in the POD format (see perlpod manpage) which is
+specially designed to be readable as is.
-1. Installation
- ------------
+=head1 NAME
- - 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
+perldos - Perl under DOS, W31, W95.
- set LFN=y
+=head1 SYNOPSIS
- to your autoexec.bat or DJGPP.ENV.
+These are instructions for building Perl under DOS (or w??), using
+DJGPP v2.01 or later. Under w95 long filenames are supported.
- - 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!
+=head1 DESCRIPTION
- - 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 :)
+Before you start, you should glance through the README file
+found in the top-level directory where the Perl distribution
+was extracted. Make sure you read and understand the terms under
+which this software is being distributed.
- - 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:
+This port currently supports MakeMaker (the set of modules that
+is used to build extensions to perl). Therefore, you should be
+able to build and install most extensions found in the CPAN sites.
- ln -s bash.exe sh.exe
- or
- stubify -g sh.exe
- stubedit sh.exe runfile=bash
+=head2 Prerequisites
- - 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:
+=over 4
- perl -S perldoc -h
+=item DJGPP
- It tries to use less.exe or more.com, but you can set your pager with:
-
- SET PAGER=path_of_your_favourite_pager
+DJGPP is a port of GNU C/C++ compiler and development tools to 32-bit,
+protected-mode environment on Intel 32-bit CPUs running MS-DOS and compatible
+operating systems, by DJ Delorie <dj@delorie.com> and friends.
-2. Building Perl
- -------------
+For more details (FAQ), check out the home of DJGPP at:
- - 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).
+ http://www.delorie.com/djgpp/
- - 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.
+If you have questions about DJGPP, try posting to the DJGPP newsgroup:
+comp.os.msdos.djgpp, or use the email gateway djgpp@delorie.com.
- - Create a symlink or copy your bash.exe to sh.exe in your DJGPP/bin
- directory.
+You can find the full DJGPP distribution on any SimTel.Net mirror all over
+the world. Like:
- ln -s bash.exe sh.exe
+ ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2*
- And make the 'SHELL' environment variable point to this sh.exe:
+You need the following files to build perl (or add new modules):
- set SHELL=c:/djgpp/bin/sh.exe (use full path name!)
+ v2/djdev202.zip
+ v2/bnu27b.zip
+ v2gnu/gcc2721b.zip
+ v2gnu/bsh1147b.zip
+ v2gnu/mak3761b.zip
+ v2gnu/fil316b.zip
+ v2gnu/sed118b.zip
+ v2gnu/txt122b.zip
+ v2gnu/dif271b.zip
+ v2gnu/grep21b.zip
+ v2gnu/shl112b.zip
+ v2gnu/gawk303b.zip
+ v2misc/csdpmi4b.zip
- You can do this in djgpp.env too. Add this line BEFORE any section
- definition:
+or possibly any newer version.
- +SHELL=%DJDIR%/bin/sh.exe
+=item Pthreads
- - If you have split.exe and gsplit.exe in your path, then rename split.exe
- to djsplit.exe, and gsplit.exe to split.exe.
+Thread support is not tested in this version of the djgpp perl.
- - Copy or link gecho.exe to echo.exe if you don't have echo.exe.
+=back
- - Copy or link gawk.exe to awk.exe if you don't have awk.exe.
+=head2 Shortcomings of Perl under DOS
- - Chdir to the gnu/perl5004/djgpp directory and type the following
- command:
+Perl under DOS lacks some features of perl under UNIX because of
+deficiencies in the UNIX-emulation, most notably:
- configure.bat
+=over 4
- This will do some preprocessing then run the Configure script.
+=item *
- The Configure script is interactive, but in most of the cases you
- just need to press ENTER.
+fork() and pipe()
- 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).
+=item *
- 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:
+some features of the UNIX filesystem regarding link count and file dates
- configure.bat -Uuseposix -dEs
+=item *
- then edited config.sh (set hostname & domainname), then
+in-place operation is a little bit broken with short filenames
- sh Configure -S
+=item *
- You can find more info about Configure's command line switches in
- the `INSTALL' file.
+sockets
- - When the script ends, and you want to change some values in the
- generated config.sh file, then run
+=back
- sh Configure -S
+=head2 Building
- after you made your modifications.
+=over 4
- IMPORTANT: if you use this -S switch, be sure to delete the CONFIG
- environment variable before running the script:
+=item *
- set CONFIG=
+Unpack the source package F<perl5.6*.tar.gz> with djtarx. If you want
+to use long file names under w95, don't forget to use
- - Now you can compile Perl. Type:
+ set LFN=y
- make
+before unpacking the archive.
- - Run the tests:
+=item *
- make test
+Create a "symlink" or copy your bash.exe to sh.exe in your C<($DJDIR)/bin>
+directory.
- 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.
+ ln -s bash.exe sh.exe
- - If you want the documentation in HTML format, then read INSTALL in
- the main perl5004 source directory.
+And make the C<SHELL> environment variable point to this F<sh.exe>:
- WARNING: if you want to use absolute path names with `installhtml',
- use something like this:
+ set SHELL=c:/djgpp/bin/sh.exe (use full path name!)
- --htmldir=f:/html
- --htmlroot='/f|/html' # "|" instead of ":" !!!
+You can do this in F<djgpp.env> too. Add this line BEFORE any section
+definition:
- or NETSCAPE does strange things.
+ +SHELL=%DJDIR%/bin/sh.exe
- - If you don't want to use the modules, then you are ready: copy perl.exe
- into your bin directory.
+=item *
- - Else install the files with:
+If you have F<split.exe> and F<gsplit.exe> in your path, then rename
+F<split.exe> to F<djsplit.exe>, and F<gsplit.exe> to F<split.exe>.
+Copy or link F<gecho.exe> to F<echo.exe> if you don't have F<echo.exe>.
+Copy or link F<gawk.exe> to F<awk.exe> if you don't have F<awk.exe>.
- make install
+=item *
- Enjoy.
+Chdir to the djgpp subdirectory of perl toplevel and type the following
+command:
- Laszlo Molnar <molnarl@cdata.tvnet.hu>
+ configure.bat
+
+This will do some preprocessing then run the Configure script for you.
+The Configure script is interactive, but in most cases you
+just need to press ENTER.
+
+If the script says that your package is incomplete, and asks 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,

+
+You can use the Configure script in non-interactive mode too.
+When I built my F<perl.exe>, I used something like this:

+
+You can find more info about Configure's command line switches in

+
+Now you can compile Perl. Type:
+
+ make
+
+=back
+
+=head2 Testing
+
+Type:
+
+ make test
+
+If you're lucky you should see "All tests successful". But there can be
+a few failed subtests (less than 5 hopefully) depending on some external
+conditions (e.g. some subtests fail under linux/dosemu or plain dos
+with short filenames only).
+
+=head2 Installation
+
+Type:
+
+ make install
+
+This will copy the newly compiled perl and libraries into your DJGPP
+directory structure. Perl.exe and the utilities go into C<($DJDIR)/bin>,
+and the library goes under C<($DJDIR)/lib/perl5>. The pod documentation
+goes under C<($DJDIR)/lib/perl5/pod>.
