Hi, I messed around and found that if in config i do $datadir = "/my/path/"; instead o f$datadir= "/my/path";
then in my script i do #!/usr/bin/perl require 'config.pl'; use $datadir."Module"; everything works again. Thanx for the suggestion tough because i didn't know how to use BEGIN now i do :-)))) Awards "Jeff 'Japhy' Pinyan" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > On Aug 2, awarsd said: > > >use lib "/path/to/Module"; > >it works just fine > > >with $dir = '/path/to'; > >use lib "$dir/Module"; > >it give me an error I also tried use lib qw() but same problem is there a > >way to fix the problem?? > > The problem is that 'use' is a compile-time directive, whereas assigning a > value to $dir happens at run-time. > > When Perl runs your program, it does a preliminary sweep over it, and does > things like include modules when 'use'd, and execute BEGIN blocks. > > A statement like 'use lib "..."' is really just > > BEGIN { > require lib; > lib->import("..."); > } > > so it happens at compile-time.
