I am trying to figure out how to install pdo_mysql on to my 4.1 copy of (the excellent) uniform server and am completely stuck - I guess at first base (I'm pretty new to this). I downloaded a copy that I assume needs to be compiled on a server - but cannot find out how to compile or install it on my local machine. I tried copying the files to the extensions folder and adding the lines: extension=pdo.so extension=pdo_mysql.so To my php.ini file but I think that was a bit too simplistic as pdo.so and pdo_mysql.so don't exist until I assume it has been compiled. Can anyone point me in the right direction please? Cheers all, Dom
