in thread Error compiling XML::LibXML::Common

And iff you're building against a static libxml2 library, you need to define -DLIBXML_STATIC. So the Makefile.PL would finally look like:
use ExtUtils::MakeMaker; WriteMakefile( NAME => 'XML::LibXML::Common', VERSION_FROM => 'Common.pm', # finds $VERSION AUTHOR => 'Christian Glahn <christian.glahn@uibk.ac.at>', ABSTRACT => 'Routines and Constants common for XML::LibXML an +d XML::GDOME', DEFINE => '-DLIBXML_STATIC', INC => "-Ic:/libxml2/include", LIBS => [ "-Lc:/libxml2/lib -lxml2", ], );
(But leave that DEFINE out if you want to build against a dll.)

Cheers,
