php problem

Hi, I have installed apache and php4 from qnxzone, and downloaded the binaries of mysql5.0.19 in /opt/mysql.
The problem is when i try localhost/phpmyadmin I get this error “Cannot load mysql extension”, I configured php.ini to load
In the phpinfo() page, mysql module doesn’t figure.

Any idea what could be the problem??

That apache/php you downloaded were compiled against the mysql that was found at the same URL. I am not sure it they will work with your mysql. YOu should either use mysql from the same URL, or recompile your own apache/php against your new version of mysql.
