| + | ====== How to build CPAN modules as non-root yet install them globally ====== | ||
| + | |||
| + | [[:people/grg|Grigoriy]] used the following approach: | ||
| + | |||
| + | <file> | ||
| + | First I installed and tested the modules locally to ~grg/installroot/ | ||
| + | by setting the following in ~/.cpan/CPAN/MyConfig.pm : | ||
| + | |||
| + | 'make_arg' => q[INSTALLDIRS=vendor DESTDIR=/home/grg/installroot], | ||
| + | 'make_install_arg' => q[INSTALLDIRS=vendor DESTDIR=/home/grg/installroot], | ||
| + | |||
| + | # only for XML::Parser::Expat: | ||
| + | # 'makepl_arg' => q[EXPATINCPATH=/opt/libexpat/current/include EXPATLIBPATH=/opt/libexpat/current/lib], | ||
| + | |||
| + | and running: | ||
| + | |||
| + | $ FTP_PASSIVE=1 PERL5LIB=/home/grg/installroot/usr/lib/perl5/vendor_perl/5.8.3 cpan | ||
| + | |||
| + | Some modules are broken and cannot be compiled or installed automatically (or | ||
| + | it's CPAN's approach used to install modules that is broken), so I installed them | ||
| + | manually by unpacking the tarball, patching/tuning and running: | ||
| + | |||
| + | $ PERL5LIB=/home/grg/installroot/usr/lib/perl5/vendor_perl/5.8.3 \ | ||
| + | perl Makefile.PL INSTALLDIRS=vendor DESTDIR=/home/grg/installroot | ||
| + | |||
| + | $ PERL5LIB=/home/grg/installroot/usr/lib/perl5/vendor_perl/5.8.3 \ | ||
| + | make INSTALLDIRS=vendor DESTDIR=/home/grg/installroot install | ||
| + | |||
| + | Then I moved /home/grg/installroot/usr/lib/perl5/vendor_perl/ | ||
| + | to /usr/lib/perl5/vendor_perl/ as root. | ||
| + | </file> | ||
