Re: CPAN modules used by non-CPAN packages

[Sven Dowideit <SvenDowideit@home.org.au>]

I too wonder if there is a 'proper' way to go from perl module name to deb

as in my Foswiki extensions debian build script, I do some pretty
simplistic looking using apt-cache, and then have a hand added list for
those I notice don't get found magically.


( resulting in http://fosiki.org/Foswiki_debian )

        #try to convert from Perl name to debian name
        #then test for availability?
        my $pkgname = 'lib' . lc($depName);
        $pkgname =~ s/::/-/g;
        my $cmd = 'apt-cache search ' . $pkgname . ' | grep perl';

        #print "DEPENDENCIES: ====== $cmd \n";
        my @pkgs = `$cmd`;

        #print  "  $pkgname found : ".join('; ', @pkgs)."\n";
        if (   ( scalar(@pkgs) == 1 )
            && ( defined( $pkgs[0] ) )
            && ( $pkgs[0] ne '' ) )
        {
            $pkgs[0] =~ s/^(\S*)\s.*$/$1/;
            $pkgs[0] =~ s/\n//;
