-The following assumes you have the GNU-Win32 package, version b17.1 or
-later, installed and configured on your system. See
-http://www.cygnus.com/misc/gnu-win32/ for details on the GNU-Win32
-project and the Cygwin32 API.
+If you read this file _as_is_, just ignore the funny characters you
+see. It is written in the POD format (see pod/perlpod.pod) which is
+specially designed to be readable as is.
-1) Copy the contents of the cygwin32 directory to the Perl source
- root directory.
+=head1 NAME
-2) Modify the ld2 script by making the PERLPATH variable contain the
- Perl source root directory. For example, if you extracted perl to
- "/perl5.004", change the script so it contains the line:
+README.cygwin32 - notes about porting Perl to Cygwin32
- PERLPATH=/perl5.004
+=head1 SYNOPSIS
-3) Copy the two scripts ld2 and gcc2 from the cygwin32 subdirectory to a
- directory in your PATH environment variable. For example, copy to
- /bin, assuming /bin is in your PATH. (These two scripts are 'wrapper'
- scripts that encapsulate the multiple-pass dll building steps used by
- GNU-Win32 ld/gcc.)
+=over
-4) Run the perl Configuration script as stated in the perl README file:
+=item Cygwin32
- sh Configure
+ The Cygwin tools are ports of the popular GNU development tools for
+Windows NT, 95, and 98. They run thanks to the Cygwin library which
+provides the UNIX system calls and environment these programs expect.
+More info about this project can be found at it's home page
+http://sourceware.cygnus.com/cygwin/
- When confronted with this prompt:
+=item libperl.dll
+
+These instructions and the default cygwin32 hints build a a shared
+libperl.dll Perl library and enables dynamically loaded extensions.

+=head1 BUILDING
+
+=head2 Prerequisites
+
+=over
+
+=item Cygwin b20.1
+
+The latest stable Cygwin suite is beta20.1. It may be
+downloaded from ftp://go.cygnus.com/pub/sourceware.cygnus.com/cygwin/latest/
+or many mirror sites around the world.
+
+=item egcs-1.1.2
+
+This port was built with egcs-1.1.2 downloaded from
+ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/egcs-1.1.2/
+
+=item install executable
+
+To make life easier, you should download
+ftp://ftp.franken.de/pub/win32/develop/gnuwin32/cygwin/porters/Humblet_Pierre_A/install-cygwin-b20.sh,
+and use it as your install "executable." Just follow the instructions
+that are embedding as comments in the .sh file.
+
+=item crypt library
+
+http://miracle.geol.msu.ru/sos/ points to two different crypt
+libraries ported to cygwin. This has been tested with the libcrypt.tgz
+by Andy Piper. His home page can be found at
+http://www.xemacs.freeserve.co.uk/
+
+=back
+
+=head2 Configure
+
+Check hints/cygwin32.sh for any system specific settings. In
+particular change libpth if Cygwin is installed somewhere other
+than /cygnus.
+
+run "sh Configure".
+
+When confronted with this prompt:
+
+=begin text
First time through, eh? I have some defaults handy for the
following systems:
.
Which of these apply, if any?
- Select "cygwin32".
+=end text
+
+select "cygwin32".
+
+Do not use the malloc that comes with perl--using the perl malloc
+collides with some cygwin startup routines.
+
+=head2 make
+
+Run "make". After that, run "make test" to see how stable your system is.
+For me, at io/taint.t you may see several Win32 "Unable To Locate DLL"
+messages (just click Ok) that requires cygwin1.dll to be present in the
+build directory or somewhere in system path (/WINNT, /WINNT/System,
+/WINNT/System32). And, at lib/io_sock.t you may see several Win32
+"Application Error" messages (just click Ok) and the test waits for a
+died child that has to be killed manually. Other test scripts seem to
+be more or less harmless. The result of ./perl harness reads:
+

+
+=head1 BUGS
+
+A lot of warnings about incompatible pointer types and comparison
+lacking a cast. This is because of __declspec(dllimport).
+
+Upon each start, make warns that a rule for perlmain.o is overrided.
+Yes, it is. In order to use libperl.dll, perlmain needs to import
+symbols from there. I saw no better solution than adding an explicit
+define to the rule.
+
+The lib/io_sock.t failure seems to be a problem with a forked child
+not having its DLLs remapped.
+
+make clean does not remove library .def and .exe.core files.
+
+ld2 script is installed with reference to source directory. You should
+change this to /usr/local/bin (or whatever) after install.
+
+.bat wrappers for installed utility scripts are not made during installation.
+
+=head1 AUTHOR
- The defaults should be OK for everything, except for the specific
- pathnames for the cygwin32 libs, include files, installation dirs,
- etc. on your system; answer those questions appropriately.
+alexander smishlajev <als@turnhere.com>
- NOTE: On windows 95, the configuration script only stops every other
- time for responses from the command line. In this case you can manually
- copy hints/cygwin32.sh to config.sh, edit config.sh for your paths, and
- run Configure non-interactively using sh Configure -d.
+=head1 DISCLAIMER
-5) Run "make" as stated in the perl README file.
+I am not going to maintain this document or this port. I only wanted
+to make perl porting a bit easier. If failed, I can't be helpful for you.
-6) Run "make test". Some tests will fail, but you should get around a
- 83% success rate. (Most failures seem to be due to Unixisms that don't
- apply to win32.)
+=head1 HISTORY
-7) Install. If you just run "perl installperl", it appears that perl
- can't find itself when it forks because it changes to another directory
- during the install process. You can get around this by invoking the
- install script using a full pathname for perl, such as:
+17..25-apr-1999. perl 5.005_03. cygwin b20.1 egcs 1.1.2.
+ far 1.60. nescafe classic.
- /perl5.004/perl installperl
+efifer@sanwaint.com - Wed May 12 17:22:42 BST 1999
- This should complete the installation process.
+ Removed all references to the impure_ptr hack since it is no longer
+ needed. Some minor cleanup of Alexander's work and a few bug fixes.
