Re: how to detect gtk installed or not

One way is to eval the appropriate require:

#! perl
use Modern::Perl;

my $r1 = eval "require Data::Dumper";
my $r2 = eval "require Non::Exist";

say $_ ? "found" : "missing" for ($r1, $r2);
[download]

which on my system prints:

 0:35 >perl 478_SoPW.pl
found
missing

 0:37 >
[download]

Hope that helps,

thanks.. unfortunately, my require is against wxPerl, and not any of the underlying system support that wx Requires. if I try to start this app, I get a missing DLL/SO error message, which I am trying to suppress as it doesn't help my users at all. using Load for wxPerl is really difficult to get working.

This means that however you tried to install wxPerl, it was a broken attempt. If the wxPerl module were installed properly, or missing completely, require should either work or fail, but not pop up a "SO missing" message. But maybe you can be a bit more explicit about how things fail for you, by posting a short, self-contained snippet together with the error messages. That would likely help us to help you better.
