Push local lib paths to @INC array

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

Hi everyone,
Is there any way to push a variable to @INC array in perl. I've noted if the full path is given then it accepts but a variable is given then it ignores,
Ex:

push @INC, "/home/user_x/custom_libs"; # working 

my $LIB_PATH = "/home/user_x/custom_libs"; 
push @INC, $LIB_PATH; # not working
[download]

Thanks,

How do you know it's "not working"? Print the contents of `@INC` before and after the push, and you'll see that it is (or you have a broken Perl installation). Note, however, that if you want to modify `@INC` before loading a module with use, you need to put the modifications in a `BEGIN` block -- and that includes setting the value of the variable.

Ya, Thanks, It is working fine inside a BEGIN block (both variable assignment and push statement)	[reply]

Use the lib pragma to add paths to @INC.	[reply]

I use 'use lib' (sorry) in combination with 'FindBin' with a Perl/Tk app I'm working on., `use FindBin; use lib $FindBin::Bin . '/lib';` [download] FindBin documentation	[reply] [d/l]

Also see FindBin is broken (RE: How do I get the full path to the script executing?) regarding the use or non-use of FindBin.	[reply]

If your application has many modules and many scripts lets say 100, instead adding these lines in each and every file and model class, you can export simply in command prompt while running the script. In linux terminal `export PERL5LIB=/home/gubendran/dashboard/trunk/lib/` This will work till you close the terminal. This avoid adding code in each and every script and you can change the library path anytime.	[reply] [d/l]


Do you know where your variables are?
