shared mysqlnd extension ...

Having now got mysql running on the PHP5.4.3 machine, I'm trying to compile mysqlnd and mysqli as extensions to load and unload as required. php_mysqlnd_config.h no longer exists, but why is the config file named config9.m4 rather than config.m4? What do I need to get these two extensions to build on Linux? My cuurent attempts based on google results only results in "Warning: PHP Startup: Invalid library (maybe not a PHP library) 'mysqlnd.so' in Unknown on line 0" after 'make' -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
