Hello,

I recently compiled and used Perl in a MinGW (not MSYS) environment. The 
compilation and installation was relatively straight-forward using these 
instructions: http://www.adp-gmbh.ch/blog/2004/october/9.html

I then used the installation for compiling and installing a number of 
Perl modules, including Gtk2. My notes are here: 
http://map.hut.fi/PerlForGeoinformatics/Install.MinGW the main points are:

* I fixed the file Config_heavy.pl in the Perl distribution to use 
-shared instead of -mdll for lddlflags.

*  I fixed the ExtUtils/Liblist/Kid.pm to recognize library names like 
lib*.dll.a (the patch is at the above page)

* I needed a parameter like dynamic_lib =>  
{OTHERLDFLAGS=> "-Wl,--out-implib=blib\\arch\\auto\\$lib\\lib$lib.dll.a 
"}to WriteMakefile when the module contained a dll

* the previous parameter makes gcc generate lib*.dll.a files into 
arch/auto directory, they need to be used in linking, i.e., there must 
be a corresponding -l*.dll in the LIBS if the module being compiled 
contains a dll also

* the Makefiles that are produced by Makefile.PL had to be repaired with 
s/\{\{/\{/g;

I'm not very knowledgeable about windows nor gcc, but the above things 
seem to work. Maybe somebody maintaining the windows port could comment 
and/or do the fixes in Perl? I'm using Perl 5.8.8.

Regards,

Ari
