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

Module::Install::External - Specify dependencies on external non-Perl things

"Module::Install::External" provides command that allow you to declaratively specify a dependency on a program or system that is not Perl.
The commands it provides are similar to those in Module::Install::Can, except that they implement an explicit dependency, in addition to just working out if the particular thing is available.

  requires_xs;
The "requires_xs" command explicitly specifies that a C compiler and the perl header files are required in order to build (at make-time) the distribution (specifically XS files).
It does not take any params, and aborts the Makefile.PL execution in a way that an automated installation or testing system will interpret as a "NA" ("not applicable to this platform") result.
This may be changed to an alternative abort result at a later time.
Returns true as a convenience.

  requires_external_cc;
The "requires_external_cc" command explicitly specifies that a C compiler is required in order to build (at make-time) the distribution.
It does not take any params, and aborts the Makefile.PL execution in a way that an automated installation or testing system will interpret as a "NA" ("not applicable to this platform") result.
This may be changed to an alternative abort result at a later time.
Returns true as a convenience.

  requires_external_bin 'cvs';
The "requires_external_bin" command takes the name of a system command or program, similar to the "can_run" command, except that "requires_external_bin" checks in a way that is a declarative explicit dependency.
The takes a single param of the command/program name, and aborts the "Makefile.PL" execution in a way that an automated installation or testing system will interpret as a "NA" ("not applicable to this platform") result.
Returns true as a convenience.

Work out how to save the external dependency metadata, in agreement with the larger Perl community.
Implement the agreed external dependency metadata solution.
