How to force default values ​​for INC and LIB for CPAN assembly (cpanm + perlbrew)

Question

Background

Work with OS X and use macports for additional utilities and libraries. macports installs everything in /opt/local . But by default, perl in macports is 5.12, specifying a higher version, for example, to break many ports, so I use my own 5.16 perl installed with perlbrew .

So, I have the default libraries /usr/lib (provided by Apple), but you want to associate XS-based perl modules with macports provided by libs and include in /opt/local .

Now the question is when installing modules with cpanm (in my perlbrew perl tree) here somehow, how to specify the global default search path for libraries and includes cpanm (to the module building process) first search /opt/local/{lib|include}

AFAIK cpanm lacks any switches for this, maybe some ENV variables? Or any simpler solution, how to edit each Makefile.PL?

Answer 1

Set half manually. Run cpanm --look Some::Dist and put the appropriate INC and LIBS or --include_dirs and --extra_compiler_flags in the build tool on the command line to configure, then complete the build, test, install and close the subshell.

Alternatively, if you need to fully automate this, use the full-featured CPAN client instead of cpanm. For example, run the cpan shell and configure makepl_arg and mbuildpl_arg . Then it is provided for subsequent installations (instead of one, as indicated above).
