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

After download Config::General module from CPAN, I decided to install it to my own directory(just copy Config::General.pm to the directory,I didn't do normal install procedure)

I write a simple test script. It can execute in unix shell.But it can't work when access it by http.Apache will report 

Can't locate Config/General.pm in @INC (@INC contains: ../lib /usr/loc
+al/lib/per
l5/5.8.2/sun4-solaris /usr/local/lib/perl5/5.8.2 /usr/local/lib/perl5/

But why it can find the pm when execute at unix shell ?

So are there any special when script execute at cgi envionment? thanks!

$ pwd
/data/zht/perl/cgi-bin
$ config
Content-type: text/html

ok$ more config
#!/usr/bin/perl
use lib '../lib';
use Config::General;

print "Content-type: text/html\n\n";
print "ok";

$ 
$ ls ../lib
Cisco         Config        Sharefunc.pm
$ ls ../lib/Config
General     General.pm

thanks!

    The current working directory of a program executed by your web server is probably not what you expect. You may need an absolute path in your use lib line. You can use Cwd to figure out the current working directory of your script in both environments.

      thanks for your reply,but I think that is not the reason.I modified the directory to absolute directory.And the error is same.

      $ more config
#!/usr/bin/perl
use lib '/data/zht/perl/lib';
use Config::General;

print "Content-type: text/html\n\n";
print "ok";

$ ls /data/zht/perl/lib
Cisco         Config        Sharefunc.pm
$ ls /data/zht/perl/lib/Config
General     General.pm

        What about permissions? See CGI Help Guide.

        MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!"
        I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
