using newer modules

[chorg]

I have a user defined modules directory.

I'm not root on the box

I want the latest CGI.pm to use for this

I don't want to break existing scripts

I definitely want to be able to say that I did not break existing scripts.

So I installed CGI.pm into this user defined directory. I use lib "/mydir" like normal, and I note that the code is using the old (root installed) version.

How can I make my code use the updated module? I know it should, but it does not seem to....

Assuming that you are using "/mydir", that refers to the top level directory "/mydir" and not to what is in your home account. You probably want something along the lines of "/home/users/myaccountname/myperlstuff" or "~/myperlstuff" to be brief.

The new dir has to be in your @INC array before the directory of the old CGI.pm

use #!/usr/bin/perl -I/home/user/mydir

or use lib '/home/user/mydir';

before your use CGI and that "should" do it. Weird if it isn't... do you do the use lib after the use CGI?

Update the good doctor is also very right, if you don't have the path right perl will just ignore it.

Ghaaa! A Grievous Error!! I was using the debugger to check what was happening, but did not use the -I switch that was in the shebang line of my program...

*sigh* Thanks for the help monks - all is well...

Heehee... find me a perl programmer who hasn't made a silly mistake or 20, and I'll show you the biggest liar in the world.

Correct me if I'm wrong but Perl will use the first module it finds (for a match) in @INC. When you use lib;, the directory is pushed onto the array @INC, so when it comes time to search for the module, the old CGI is found first. You'll want to use unshift to add the directory to @INC.

Update: I was wrong.

No, Camel book says use lib is almost the same as

BEGIN { unshift @INC, LIST; }

except it supports platform specific stuff... so it should work.

Check out this discussion of @INC. Pay close attention to chromatic's reply.
