Perl Modules

Introduction to Perl Modules

The Perl module packages (also referred to as Distributions, because each can contain multiple modules) add useful objects to the Perl language. The packages listed on this page are required or recommended for other packages in the book. If they have dependent modules, those are either on this page or else on the next page (Perl Module Dependencies).

In many cases, only the required or recommended dependencies are listed - there might be other modules which allow more tests to be run, but omitting them will still allow the tests to PASS.

For a few modules, the BLFS editors have determined that other modules still listed as prerequisites are not required, and omitted them.

Where an alphabetically-earlier dependency of the same module pulls in a dependency, it is not mentioned for the later dependencies of the same module. You should build the listed dependencies in order.

It is generally worth running the tests for perl modules, they often can show problems such as missing dependencies which are required to use the module. Here, the editors have attempted to separate those dependencies which are only required for running test suites, but they will not be mentioned for a module where one of its dependencies uses that module for its own test suite. That is to say, if you intend to run the test suites, please run them for each dependency of the module.

It is possible to automatically install the current versions of a module and all missing or too-old dependencies recommended by upstream using CPAN. See CPAN automated install of perl modules at the end of this page.

Most of these modules only install files below /usr/lib/perl5/site_perl/5.xx.y and those will not be documented. One or two install programs (mostly, perl scripts), or a library, into /usr/bin/ or /usr/lib/ and these are documented.

CPAN automated install of perl modules

Automatic Installation of Perl Modules.

There is an alternate way of installing the modules using the cpan shell install command. The command automatically downloads the latest source from the CPAN archive for the module and any missing prerequisite modules listed by upstream. Then for each module it extracts it, runs the compilation, the tests and installs it.

You still need to install any non-perl dependencies before running the automated installation method. You may wish to clean out the build/ directory after installing, to free up the space. If any post-install actions such as creating a symlink are mentioned, you should also do those.

The first time you run cpan, you'll be prompted to enter some information regarding download locations and methods. This information is retained in files located in ~/.cpan.

In particular, you may wish to configure it so that Sudo-1.9.14p3 is used for the installs, allowing you to build and test as a regular user. The following examples have not used that approach.

Start the cpan shell by issuing 'cpan' as the root user. Any module may now be installed from the cpan>  prompt with the command: 

install <Module::Name>

For additional commands and help, issue 'help' from the cpan>  prompt.

Alternatively, for scripted or non-interactive installations, use the following syntax as the root user to install one or more modules: 

cpan -i <Module1::Name> <Module2::Name>

Review the cpan.1 man page for additional parameters you can pass to cpan on the command line.
