Hi
I need to use a non-core, non-standard module on a Makefile.PL.
- I would like to abort Makefile.PL run if it is not installed;
- I would like it to be installed if being run inside CPAN;
Hints?
Very recent versions of CPAN has support for 'configure_requires',
which looks like the right way to do that.
Hmms... that might be a solution when installing the module through
CPAN. But if the user runs Makefile.PL manually she will get a Can't
locate module message.
Not yet the thing I would love.
The "Can't locate module" message would seem to indicate exactly what's wrong
and clearly suggests what needs to be done to fix it. If they're installing
by hand they're used to resolving dependencies by hand anyway.
If it's not a good enough message, make a better one. Makefile.PL is just a
program. Unlike require dependencies, it's ok to die if you're missing
configuration dependencies because your Makefile.PL would have done that anyway.
my @missing_deps;
for my $module (@configure_dependencies) {
unless( eval qq{require $module} ) {
push @missing_deps, $module
}
}
die "Makefile.PL requires @{[ join ',', @missing_deps ]}.\n"
if @missing_deps;
