perl -MCPAN -e shell
(to get an interactive CPAN shell)
perl -MCPAN -e 'install
Time::JulianDay' (if you know the name of the module, you can
install it directly without interacting with the CPAN shell)
Within the CPAN shell:
i /expression/ will search for a
Perl module containing expression,
and
install module will
install the module.
Example:
perl -MCPAN -e shell
i /JulianDay/
install Time::JulianDay
Note: if you are behind a firewall, you may wish to use
passive FTP with Perl's Net::FTP module. Set the environment variable FTP_PASSIVE 1 (or any non-zero value)
to use passive FTP when downloading Perl modules through CPAN.
To manually install a Perl module:
1. Download the Perl module from CPAN or other site.
2. Extract the tarball.
3. Run perl Makefile.PL
4. Run make
5. Run make test
6. Run make install
Note: you should use the same compiler to build Perl modules that you
used to build Perl. For example, if you are building Perl modules with gcc and are using a version of
Perl that was supplied with your distribution (ex. Solaris 8 includes
Perl 5.005_03), you may run into errors.
Example: building Perl DBI with gcc on Solaris 8 system with Perl
5.005 (part of the Solaris 8 release).
cc: unrecognized
option `-KPIC'
cc: language depend not recognized
The Makefile for Perl modules is created using flags for SUNWspro (the compiler used to build Perl 5.005 for the Solaris 8 release), not gcc. As a workaround, you could build Perl from source using the gcc compiler, or obtain a packaged version of Perl that is built with gcc, such as those at Sunfreeware. This comp.lang.perl.modules post has more information.
