Subject: Build error when using non-standard libxml2 installation

I ran into a build problem when trying to link to a libxml2 that had been installed into a non-standard location. XML::LibXML version 2.00007 uname: Linux 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux Perl: 5.10.1 The error I got upon running perl Makefile.PL was: libxml2, zlib, and/or the Math library (-lm) have not been found. Try setting LIBS and INC values on the command line Or get libxml2 from http://xmlsoft.org/ If you install via RPMs, make sure you also install the -devel RPMs, as this is where the headers (.h files) are. After various efforts to rebuild libxml2, I started to think that it was actually installed correctly all along and that the Makefile.PL wasn't finding it properly for some reason. After digging a bit I found that adding "LIBS => $config{LIBS}" to the call to check_lib fixed the problem. The call to Devel::CheckLib::check_lib was returning false because it didn't know to look in the right directory for the library. I also added "debug => $config{DEBUG}" to the same call FYI, it might come in handy as well. Not sure if this is really a Makefile bug or if there was a different way I could have resolved the issue, but I figured I'd mention it just in case. Thanks for a great module!

Hi L, thanks for reporting it. I now fixed it in XML-LibXML-2.0008 . I did not add the "debug" thing because I saw no mentions of it in the Devel::CheckLib document. Regards, -- Shlomi Fish On Mon Oct 22 06:00:49 2012, lrw4400@att.net wrote: Show quoted text
