From: PerlFAQ Server on 28 Jul 2010 00:00 This is an excerpt from the latest version perlfaq8.pod, which comes with the standard Perl distribution. These postings aim to reduce the number of repeated questions as well as allow the community to review and update the answers. The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 8.47: How do I keep my own module/library directory? When you build modules, tell Perl where to install the modules. If you want to install modules for your own use, the easiest way might be "local::lib", which you can download from CPAN. It sets various installation settings for you, and uses those same settings within your programs. If you want more flexibility, you need to configure your CPAN client for your particular situation. For "Makefile.PL"-based distributions, use the INSTALL_BASE option when generating Makefiles: perl Makefile.PL INSTALL_BASE=/mydir/perl You can set this in your "CPAN.pm" configuration so modules automatically install in your private library directory when you use the CPAN.pm shell: % cpan cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl cpan> o conf commit For "Build.PL"-based distributions, use the --install_base option: perl Build.PL --install_base /mydir/perl You can configure "CPAN.pm" to automatically use this option too: % cpan cpan> o conf mbuild_arg "--install_base /mydir/perl" cpan> o conf commit INSTALL_BASE tells these tools to put your modules into /mydir/perl/lib/perl5. See "How do I add a directory to my include path (@INC) at runtime?" for details on how to run your newly installed modules. There is one caveat with INSTALL_BASE, though, since it acts differently than the PREFIX and LIB settings that older versions of "ExtUtils::MakeMaker" advocated. INSTALL_BASE does not support installing modules for multiple versions of Perl or different architectures under the same directory. You should consider if you really want that , and if you do, use the older PREFIX and LIB settings. See the "ExtUtils::Makemaker" documentation for more details. -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.
