Module::Install::Can(3)                    User Contributed Perl Documentation


NAME
       Module::Install::Can - Utility functions for capability detection

DESCRIPTION
       "Module::Install::Can" contains a number of functions for authors to
       use when creating customised smarter installers. The functions simplify
       standard tests so that you can express your dependencies and conditions
       much more simply, and make your installer much easier to maintain.

COMMANDS
   can_use
         can_use('Module::Name');
         can_use('Module::Name', 1.23);

       The "can_use" function tests the ability to load a specific named
       module. Currently it will also actually load the module in the process,
       although this may change in the future.

       Takes an optional second param of a version number. The currently
       installed version of the module will be tested to make sure it is equal
       to or greater than the specified version.

       Returns true if the module can be loaded, or false (in both scalar or
       list context) if not.

   can_run
         can_run('cvs');

       The "can_run" function tests the ability to run a named command or
       program on the local system.

       Returns true if so, or false (both in scalar and list context) if not.

   can_cc
         can_cc();

       The "can_cc" function tests the ability to locate a functioning C
       compiler on the local system. Returns true if the C compiler can be
       found, or false (both in scalar and list context) if not.

   can_xs
         can_xs();

       The "can_xs" function tests for a functioning C compiler and the
       correct headers to build XS modules against the current instance of
       Perl.

TO DO
       Currently, the use of a "can_foo" command in a single problem domain
       (for example "can_use") results in the inclusion of additional
       functionality from different problem domains (for example "can_run").

       This module should ultimately be broken up, and the individual
       functions redistributed to different domain-specific extensions.
