GD Library error - undefined function imageantialias

[plathw]

I am getting the following error that I believe tells me that GD Library is not working properly:

Fatal error: Call to undefined function imageantialias() in /var/www/web40/web/cap.php on line 51

I am running Ubuntu with ISPconfig. I checked my phpinfo and GD library shows the following:

GD Support enabled
GD Version 2.0 or higher
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.1.10
T1Lib Support enabled
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled

Any ideas on what could be going on?

The only hint the php doc's give, that this function only exists with the bundled version of GD, so I'd guess this is not the "bundled" one.

Does
var_dump( function_exists('imageantialias'));
return false?

Also
var_dump( function_exists('imagecreatetruecolor'));
should return false is it is another "truecolorimageonly" function.

That should be the GD bundled with ubuntu, but I'm not 100% sure.

How would I run those? Sorry, kind of a noob here.

You can put them in a PHP script, e.g. like this:

PHP Code:

<?php

if (false === var_dump( function_exists('imageantialias'))) echo 'error1';
if (false === var_dump( function_exists('imagecreatetruecolor'))) echo 'error2';
?>

This post from Ben (should be post #4 in this thread) got lost today because of a server failure. I apologize and add it again for the sake of completeness:

just open your shell and type the following:

php -r "var_dump( function_exists('imageantialias'));"
and
php -r "var_dump( function_exists('imagecreatetruecolor'));"

That should for my expectiation output both true or both false.

Here is the output:

bool(false) bool(true)

So the imageantialias does not exist. Which distribution are you using, and how exactly did you install PHP?

I did the Ubuntu/ISPconfig perfect set up here:

It seems you must compile PHP yourself:
