I’d like to use PDO in conjunction with MySQL, but in the PHP installation shipped with OS X by default only pdo_sqlite is enabled. I do not want to compile my own Apache or PHP so the way to go is to simply add the pdo_mysql module. I followed these instructions but after running phpize there were some warings on my screen and no makefile to be found. My current PHP version is 5.2.8 and I used the source of 5.3.0, so I tried again with 5.2.10 (since no other version was available at the PHP download page). Both yield the same result, namely that it compiles, installs and won’t start.
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so' - (null) in Unknown on line 0
Following instructions in the comment to remove all architectures but the x86_64 have no effect. I think I have to compile my own PHP installation and have apache use that. Which sucks so much I decided to just wait for Snow Leopard and pray that either pdo_mysql is installed or dynamicly loading libraries is allowed there. I am happy to inform you all that the first is the case. Hurray!
