Re: Problem using use CGI and LWP modules together

I am trying to develop a script to run on a web server. It uses the
modules
GD to do stuff with images
CGI to get the parameters from the URI
LWP to fetch stuff from the web

If my program begins
#!/usr/local/bin/perl
use strict;
use GD;
use GD::Text;
use CGI qw(:standard);
use LWP::Simple;
I get the error message
Prototype mismatch: sub main::head: none vs ($) at s4pngu.pl line 6



My guess is that the LWP and CGI modules are incompatible somehow. Am I
right? Or am I invoking them wrong? Is there a recommended solution?


It does look like a name clash. I am able to reproduce this same error
on my system (perl 5.8.8).

You can use the OO features of CGI and avoid importing subroutines from
the module into your main:: namespace, provided you are comfortable
with the OO method of programming for CGI:

use CGI;
use LWP::Simple;

You will then have to define a CGI object and use method calls instead
of simple function calls.

Note that the following also demonstrates the error:

use CGI qw(head);
use LWP::Simple;

which really does indicate a 'head' clash.
