using my module.pm in different directory error

t-rex has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks, This is my directory structure

urs.pl
src
now this src contains server and client directories
src-> server client
and client contains Yaml_Lib.pm Client_lib.pm Run_lib.pm
[download]

now the urs.pl uses the files Yaml_libm.pm and others in the client folder.

I want to know how should I include them in my urs.pl , I checked on this site and I got to know about use lib ‘..’;

but when I do it I still get error that Yaml_Lib.pm and others not found in @INC

use lib ‘src/client/’;
use Yaml_Lib.pm
use Client_lib.pm
[download]

Note that this structure (entire scripts) can be in any directory eg; now my pwd is different it could be different on other machine but inside structure(scr/client/) remians constant.

Hi t-rex, If your module files are always located in the same place in the file system, use `use lib '/absolute/path/to/modules';` [download] If your module files are always located in the same place relative to the script, use `use FindBin; use lib "$FindBin::Bin/path/to/modules";` [download] Both solutions are independent of the current working directory because they use absolute paths. Also, you wrote "`use Yaml_Lib.pm`", I'm assuming you meant "`use Yaml_Lib;`" because the `.pm` extension is added automatically by Perl. Hope this helps, -- Hauke D	[reply] [d/l] [select]

See docs for File::FindLib, use `use File::FindLib 'src/client';`	[reply] [d/l]

Quick and dirty: PERL5LIB Long and clean: use proper namespaces and package your script and modules into a distribution as you would for CPAN. eg. put your modules under a namespace like "App::URS::" which would equate to a directory like `App/URS/`, install them into the site_perl tree and then your script should use them with lines like: `use App::URS::YAML;` [download] You'll probably have to read up on packages and it would benefit to look at Module::Starter or similar. See also Simple Module Tutorial and How to make a CPAN Module Distribution. It's a long road for sure but well worth it and will make problems like the one you currently have just vanish.

Add a BEGIN{} to your urs.pl which add paths of your pm files to @INC: `BEGIN { unshift @INC, './path/to/lib/dir1'; unshift @INC, '/full/path/to/lib/dir2'; }` [download]	[reply] [d/l]

path to lib which change as in lets say i launch script from /tmp/ something and next i launch it from /home/userx/run_auto.... so the path inside run_auto remains constant but where i launch the script from keeps changing...	[reply]

I am not sure to understand. Are you saying that your modules will not always be in the same place? Or the opposite?	[reply]
