Calling Subroutines From Another File: Path Problem

anshumangoyal has asked for the wisdom of the Perl Monks concerning the following question:

I am having 20 Subroutines which are common to almost 30+ files. Instead of adding all these subroutines in each file I created a file CommonSubs.pm and placed in location C:\DIR1\DIR2\DIR3\CommonSubs.pm.

My all other Files are also located in the same location. E.g. File1.pl calling CommonSubs.pm is located at C:\DIR1\DIR2\DIR3\File1.pl.

CommonSubs.pm has a line which says "Package CommonSubs"

Problem is when I am calling any of my file from an other location, it gives me error. e.g. I call Perl C:\DIR1\DIR2\DIR3\File1.pl while in d: Directory, it throws an error.

While when I cd to C:\DIR1\DIR2\DIR3\ Directory and then call File1.pl it runs fine.

I know this is the issue with Path's but how to make it generic so that from where ever I call this File1.pl (Giving it's complete path) it is executed without error

see Perl Modules to learn what modules are.

see use for the most common way to include them.

see @INC for how to setup the places where "use" constructs look for their library files.

Here are some options:

Place use lib 'C:DIR1/DIR2/DIR3'; near the beginning of File1.pl

Invoke perl with a -I command-line option:

perl -IC:/DIR1/DIR2/DIR3 File.pl
[download]

Add C:/DIR1/DIR2/DIR3 to the system environment variable PERL5LIB

See perlrun.

Hope that helps,
