building perl swig with MingW

[guillaume huby]

Hello,

I experience some troubles building perl bindings on MingW.
Here is my config :

Windows XP;
MingW 5.1.6 + MSys;
Gdal1.6.2 sources from website;
ActivePerl 5.10;

I successfully built gdal library using MingW. Then I build perl bindings :

perl Makefile.pl -> everything looks fine;
dmake -> no error message;
dmake test -> error message :
<PerlPath>\bin\perl.exe "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib\lib', 'blib\arch')" t/*.t
t/gdal....
#   Failed test 'use Geo::GDAL;'
#   at t/gdal.t line 2.
#     Tried to use 'Geo::GDAL'.
#     Error:  Can't load '<Gdal_source_path>\swig\perl\blib\arch/auto/Geo/OGR/OGR.dll' for module Geo::OGR: load_file: Access to this memory location is not valid at <PerlPath>/lib/DynaLoader.pm line 202.
#  at <Gdal_source_path>\swig\perl\blib\lib/Geo/OGR.pm line 12

Undefined subroutine &Geo::GDAL::GetDriver called at t/gdal.t line 57.
# Looks like you failed 1 test of 1.

The "<Gdal_source_path>\swig\perl\blib\arch/auto/Geo/OGR/OGR.dll" file successfully pass dependency walker test.

Does anyone has an idea of what went wrong ? Did I missed something somewhere ?

Thanks for replies !

Regards,
Guillaume.

The problem is that ActivePerl is compiled with VC and you can't mix
MinGW,which uses gcc, with that.

Compiling Perl with MinGW is not difficult, however, and there are
binary distributions too.

Sorry for being so slow to answer.

Cheers,

Ari

Thank you for your reply !

As a first turn around, I used the compiled files of Geo::Gdal of GeoInformatica in my ActivePerl directories. It is not very clean but it works well !

I did not found time to compile perl with MinGW yet, but I hope to be able to try soon.

Cheers,
Guillaume.
