Re^2: perlbrew/cpanm on 64 bit Ubuntu

Add them WHERE in the config?

I have installed the 32bit libraries and multilib compilers, and it turns out that neither the 32bit nor the 64bit libraries end up in the main /usr/lib directory that is mentioned in Makefile.PL.

In the perlbrew environment, running
cpanm XML::LibXML

still reports:

Configuring XML-LibXML-2.0019 ... N/A
! Configure failed for XML-LibXML-2.0019. See /home/emgrasso/.cpanm/wo
+rk/1375587018.8608/build.log for details

and /home/emgrasso/.cpanm/work/1375587018.8608/build.log says:

If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.

I don't think it is talking about the cpanm command line.

The perlbrew environments don't seem to contain any CPAN directories for config files where I could set o conf makepl_arg. (Does cpanm pay attention to those? If so, what format would I need to use so Makefile.PL would search the existing paths at well as the special 32 or 64 bit paths?)

I don't think it is talking about the cpanm command line That's right - it's talking about the `perl Makefile.PL` command line .... which is the command you would run if you wanted to build XML::LibXML "manually". In that case you would cd to the top-level directory in the XML-LibXML source and run something like: `perl Makefile.PL INC="-I/usr/include/x86_64-linux-gnu" LIBS="-L/usr/li +b/x86_64-linux-gnu -lxml2 -lz -lm"` [download] You would then follow that with `make test` then (assuming `make test` went satisfactorily) `make install` I don't know how you'd incorporate that command line requirement into the automated cpanm procedure. (I'd just do it "manually".) Alternatively, adding `/usr/include/x86_64-linux-gnu` to the CPATH environment variable and adding `/usr/lib/x86_64-linux-gnu` to the LIBRARY_PATH environment variable might also work - at least if you're using a gcc compiler: `export CPATH=/usr/include/x86_64-linux-gnu:$CPATH export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LIBRARY_PATH` [download] Cheers, Rob	[reply] [d/l] [select]

`cpanm XML::LibXML --configure-args 'INC="-I/usr/include/x86_64-linux-g +nu" LIBS="-L/usr/lib/x86_64-linux-gnu -lxml2 -lz -lm" '` [download] tells cpanm to pass those parameters to perl Makefile.PL of XML::LibXML but not to its prereqs.	[reply] [d/l]
