Re^2: Basic - Perl5lib

[aquarium]

..and typically you'd set that environment variable so that all your processes/scripts had access to that additional module directory. otherwise just add an additional module directory directly in a perl script by pushing it onto @INC in a begin section. example for modules in specified directory and/or current directory

BEGIN {
  $my_module_dir = '~/myperl_modules/`;
  push(@INC, ('.',"$my_module_dir"));
}
  use mymodule;
...

oracle installs (and embedded) perl and it's own set of modules, and sets perl5lib. so not a good idea to modify perl5lib on oracle systems unless you really know what you're doing.

The more common way to add to @INC from within your program is with use lib. The following is equivalent to (more concise than) the code above:

use lib qw( . ~/myperl_modules/ );
use mymodule;

...except that use lib puts the extra dirs at the start of @INC (giving them precedence over system modules, which is normally what you want) while your use of push puts them at the end (giving system modules precedence, which is normally not what you want).

Thanks for your replies. How can I set the PERL5LIB environment variable if I don't have one?

If I do manage to find my missing PERL5LIB, is it shared by all my Perl installations?
