cdbconnection error

I am installing yiiframework on ubuntu 10 runing under vmware.

While trying to generate crud model, i receive cdbexception error.

Attached is the screenshot.

I wonder what kind of setting i need to do.

thank you

Solved it.

Need to install pdo mysql.

When installing a fresh copy of the framework it’s a good point to check the requirements - http://www.yiiframework.com/doc/guide/1.1/en/quickstart.installation#requirements
