I am installing PHP 5.2.5 with PDO for informix 1.2.0. I am facing a problem during make test of PHP with pdo option of informix. The make test displays errors with the content:

Fatal error : Uncaught exception 'PDOException' with message 'invalid
data source name' in /path/of/php/ext/pdo_informix/tests/fvt.inc: 41

I am clueless regarding this and am unable to go further. If I omit
PDO_INFORMIX, php is working fine.

My OS Suse Linux version is 10 and Informix version is also 10.

Please let me know, what I to do further.
