I followed some tutorial on the web but I can't figure out how to install them.
I have RH5 and php 5.3.6.
I typed yum install php-gd
and it get me
Parsing package install arguments No Match for argument: php-gd Nothing to do
Tryed with php5-gd
and still nothing to do.
How to install them?
It looks like you have a compiled install of php. You just need to install GD and recompile php with support for gd
yum install php5-gd
really should install the needed module. If it doesn't do it, the module is probably already installed. If you create a simple web page containing lineand load that page in your web browser, does it list GD extension?
