PHP5 GD Error: libt1.so.5: cannot open shared object file
Posted On Jun 07, 2009 at 9:38 pm
Do you have GD and the PHP GD extension installed and yet it's not getting loaded into your PHP? If you getting the following error logged to your php error log, then the source of the problem is simple.
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/extensions/gd.so' - libt1.so.5: cannot open shared object file: No such file or directory in Unknown on line 0.
This error means that you do not have the t1lib (t one lib) package installed. Search for this package within your distribution's software manager (apt, yast, etc) or you can download it from www.t1lib.org.

Wonderful! Many thanks for this information. It saved me from the perils of being stuck in a puddle of goo.

As you are probably aware, PHP has bundled an upgraded GD library for some time, which supports image rotation, convolution and alpha blending. The package php5-gd still uses Boutell's version of the library, which restricts the abilities of the PHP module.

The other thing I thought of - this is an obscure outside possibility, but worth checking - if you have a Wordpress caching plugin installed you need to delete the cache and disable the plugin and then re-enable it.
