How to require a file and use its subroutine

Question

how can I use a subroutine in a required file, when the subroutien has to get variables:

file.pl:

...
sub func{
  my ($var) = @_;
  ..

}

main.pl:

..
require "file.pl";
func(1);
..

this is not working for me, I'm getting an error says Undefined subroutine &main::func ..

I can see only what you post. Ok, did you check path to required file? Are any packages in `file.pl`? — mpapec, Oct 10 '13 at 08:00
Is `file.pl` also required in other packages that `main.pl` used? — Logan Ding, Oct 10 '13 at 08:11

Perl was telling you that no main::func exists (main is default package), so you need to prefix your function with qualified package name,

require "file.pl";
Naming::func(1);
