Dear ladies and gentlemen, when trying to install LibXML on Windows7 I had problems with the check_lib() call in _libxml_check_lib_with_config_LIBs(). - CheckLib.pm looks for the hash entry 'libpath' not 'LIBS', so the code in Makefile.PL should be something like $conf_LIBS =~ s/ -l\w+//g; return check_lib( .... libpath => [split(/\s/,$conf_LIBS)], ... ) - The command line argument 'INC' has to be given without '-I' prefixes for CheckLib to work, but during Makefile generation the prefix is not added - I tried to use the command line argument 'LDFLAGS' but it has no effect on the check in CheckLib or Makefile generation I ended up disabling the checks and editing parts of the generated Makefile, then an 'nmake install_perl' worked.

OK, I guess by "LibXML" you mean the "XML-LibXML" distribution (please correct me if I'm wrong). Anyway, which perl distribution and version are you using? I would recommend Strawberry Perl - http://strawberryperl.com/ . Show quoted text

Actually, it looks for "LIBS" too. I checked it in the one under inc. Show quoted text

OK, it may be a problem with Devel::CheckLib. Regards, -- Shlomi Fish

It would helpful to know which version of XML::LibXML and Perl and which C compiler was used. Since 'nmake' was mentioned, I guess that it's a ActivePerl/MSVC setup. Having a look at Makefile.PL, it seems that building with MSVC was never supported.

I have to retract this statement. I was able to build XML::LibXML with MSVC with a small adjustment to Makefile.PL (see attachment). It's only important to pass the include and library paths like you would for gcc. The following worked for me: perl Makefile.PL "INC=-IC:\path\to\libxml\include -IC:\path\to\iconv\include" "LIBS=-LC:\path\to\libxml2\lib"

Thanks Neil for the patch. I applied it now in the repository. Furthermore, I'm resolving this bug as REJECTED because Dr. Benkert was not responsive for many months and did not provide us with the necessary info. Feel free to reopen this bug or file a new one (and please be more responsive next time).
