GD2 Problems? This may help...

[Browzer]

Using Apache 2.2.4 and PHP 5.2.1 on Windows, I was getting the "Call to undefined function imagecreate()" error.  I solved the problem, but the solution for my situation was not documented anywhere on the web, so I am posting it here.

 

The root of the problem is that the GD2 library is not installed.  The first thing to do is make sure the GD2 library.  Your php.ini file should have these lines

 

extension_dir = "C:\PHP\ext"

extension=php_gd2.dll

 

It seems like this solves 99% of the cases...but not mine!  The real problem was that PHP improprely edited Apache's httpd.conf file during installation.  MAKE SURE the httpd.conf file has a clean reference to PHP that looks something like:

 

# For PHP 5:

LoadModule php5_module "c:/php/php5apache2.dll"

AddType application/x-httpd-php .php

 

# configure the path to php.ini

PHPIniDir "C:/php/"

 

In my case, all that text was on a single line with some odd characters (improper newlines?) in there.  I think this was caused by a problem in the installation.  Once I cleaned it up to look like the lines above, it worked.

 

Anyway, hopefully this will save people some time.
