Bug #81297 for XML-LibXML: link against xml2...no on Solaris

Tue Nov 20 07:29:41 2012 raherh [...] gmail.com - Ticket created

Subject:

link against xml2...no on Solaris

Version 2.0007 is ok during perl Makefile.PL. Higher versions give the following. Solaris is 5.10 and libxml2 2.7.8. enable native perl UTF8 running xml2-config...ok (2.7.8) Checking for ability to link against xml2...no 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.

Can you copy+paste the output of perl Makefile.PL DEBUG=1 here? A Mercurial bisecting would be useful too: https://bitbucket.org/shlomif/perl-xml-libxml Regards, -- Shlomi Fish

$ perl Makefile.PL DEBUG=1 enable native perl UTF8 running xml2-config...xml2-config --version xml2-config --libs xml2-config --cflags ok (2.7.8) Checking for ability to link against xml2...no 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. Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter to see the exact reason why the detection of libxml2 installation failed or why Makefile.PL was not able to compile a test program. Checking for ability to link against libxml2... $ Radek

Well, it seems that either "-lm" is missing (unlikely) or zlib is. Please install a usable zlib library. Else, you may try to debug the Makefile.PL process using "perl -d". See: http://perl-begin.org/topics/debugging/ Regards, -- Shlomi Fish

I upgraded zlib from 1.2.5 to 1.2.7, no change. If XML::LibXML 2.0007 installs ok, I'd say something's wrong with a version > 2.0007. What has been changed? Radek

Running perl -d Makefile.pl gives: LIBS argument badly-formed: -R/usr/local/lib Show quoted text

____________ and running xml2-config --libs gives: -L/usr/local/lib -R/usr/local/lib -lxml2 -lz -lpthread -liconv -lm - lsocket -lnsl -R/usr/local/lib argument is not accepted by Devel::CheckLib. It requires all arguments to begin with -l or -L. Don't know why. Radek

Thanks for the investigation. I cannot find an "-R" flag in "man gcc" here. What does it do? Anyway, this may be a Devel::CheckLib bug, or you can try working around it. Regards, -- Shlomi Fish

-R is a runtime path library for a compiler. I had a look at libxml2 distribution and appears it's special for Solaris. I filed a bug for Devel::CheckLib but there are too many unresolved bugs there. Radek

Same problem here. Devel::Checklib is locally included in the build directory under inc/, so I patched it. In assert_lib: my (@libs, @libpaths, @headers, @incpaths); to: my (@libs, @libpaths, @headers, @incpaths, @rpaths); die("LIBS argument badly-formed: $arg\n") unless($arg =~ /^-l/i); to: die("LIBS argument badly-formed: $arg\n") unless($arg =~ /^-[lLR]/i); And: (map { "-L$_" } @libpaths), to: (map { "-L$_" } @libpaths), (map { "-R$_" } @rpaths), Sorry for the not-official patch format...

Remove the "i" in "/i"...

XML::LibXML now uses Alien::Libxml2 to find or link against libxml2. Please open an issue for that distribution if this problem still occurs.
