Exporter and qsub

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

Hi,

I am trying to run my perl script on a super computer. This script uses a module I made. Everything is working fine when I run it directly on a node, but when I submit my script with qsub, I get the : Can't locate mymodule.pm in @INC error

The node where I run it directly and the node where I submit my script are the same. Same modules loaded, ect. I don't understand where could be the problem. Any idea?

Thank you very much

I presume the module is simply located in the same directory as the script rather than being "installed"? Perl will usually look into the current directory (but not when using -T), but the current directory is not necessarily the one in which the script is located. Adding the following to your script should tell Perl where to look: `use Cwd qw( realpath ); use File::Basename qw( dirname ); use lib dirname(realpath($0));` [download]	[reply] [d/l]

What is in @INC (the tail output of `perl -V`)? And how does it compare when run from qsub `print qx{$^X -V}`?	[reply] [d/l] [select]

Hi, Thanks for your reply, and sorry, but what does `print qx{$^X -V}` is supposed to do? I cannot run it... :/	[reply] [d/l]

Its perl -V from within your program (or qsub) In anycase, its all about @INC	[reply]

Hi, Try printing your %ENV and @INC in both ways to make sure they are the same. J.C.	[reply]

Yeah! It is working :) . (adding the `use lib ...` to tell him where to look at - thxs ikegami-, and also I was running it from the wrong dir without realizing). Thank you so much for your advices	[reply] [d/l]
