[Lucky]

web server: apache2.2.4
PHP: 5.2.2
MySQL: 5.0.19

when I install Testlink 1.7.1, it always prompts like that

Checking PHP version: OK! ( 5.0.0 [minimun version] <= 5.2.5 [your version] )

Warning!: You are using a M$ Operating System, be careful with authentication problems
between PHP 4 and the new MySQL 4.1.x passwords
Read this MySQL - A.2.3. Client does not support authentication protocol

Checking if Register Globals = OFF: OK!
Checking PHP DB extensions Warning!: Your PHP installation don't have the MySQL extension - without it is IMPOSSIBLE to use Testlink.Failed!
Checking if sessions are properly configured: OK!
Checking if ../gui/templates_c directory exists: OK!

Hi,

I face the same problem in my environment.

"Checking PHP DB extensions Warning!: Your PHP installation don't have the mysql extension mysql- without it is IMPOSSIBLE to use Testlink.Failed!"

Check http://cz2.php.net/mysql

The above link didn't work. Because of this error i can't use test link. Please help to resolve this.

this is NO a TestLink error, do some search on google regarding PHP and how to enable extension
