in thread finding the absolute path to a module, from the module's, perspective

Well it works for me. File::Spec 0.88, Cwd 2.20.

What does it print for you from the commandline?

Are you sure what you think is getting loaded is in fact getting loaded. Try appending 

print "$_\n" for %INC";

Also, try just printing __FILE__

    This is pretty weird, but I think I've figured it out;

    doing a, 

     
print __FILE__;

    inside my module will return something like: 
     
/lib/Stuff/Template.pm
    File::Spec has a method called, file_name_is_absolute(), which basically on Unix, looks for a '/' as the first character -> 
     
sub file_name_is_absolute {
    my ($self,$file) = @_;
    return scalar($file =~ m:^/:s);
}

    File::Spec will consult this method before it tries to piece together a absolute path; thus, File::Spec isn't even attempting to make an absolute path from the information from __FILE__

    The workaround I've done is simply to hack the first, '/' off.

    Changing my FOO.pm to something like: 

     
package FOO; 
use File::Spec;

require Exporter; 
@ISA = qw(Exporter); 
@EXPORT = qw(bar); 

sub bar { 
    print __FILE__; 
    print '<p>';
    print File::Spec->rel2abs(__FILE__) . "\n";
}

    Will print:

    lib/FOO.pm

    /usr/home/user/www/cgi-bin/lib/FOO.pm

    So, it doesn't look like it's *really* File::Spec's fault, but what would cause Perl to put a '/' at the beginning of the path in my module?

    Hmm...

      chroot? mod_perl?
