Since i'm not obtaining any kind of response from people o first answered me. I guess is better to talk through here. To my first message, Micah Gersten asked me if i've placed the extension path on 'php.ini' my answer was yes, i've tried to do that but it still wasn't loading the extension. Jochem Maas advised me to place the complete path to the extension like this 'extension=/usr/lib/php/extensions/no-debug-non-zts-20060613/http.so', i've also tried it, again with no success. In the last response, Thodoris told me to place in the php.ini the line 'extension_dir=".;/usr/lib/php/extensions/no-debug-non-zts-20060613;/usr/lib/php/modules"', adding again the extension directive 'extension=http.so'. Well, seems like there is no such path like '/usr/lib/php/modules', for the sound of it, the closest match i get is '/usr/include/php/ext/' (path with the header files of each extension) or '/usr/libexec/apache2' (path also with '.so' files regarding apache modules). Either way, i've changed the unexisting path by each one of these and again nothing happened. I don't know what else i can do. Could somebody that has installed PECL extensions successfuly on Leopard help me? I just need to know what i must do in the inicialization files (php or apache) just like i was installing my first extension and having the fact that there is the native Leopard 'php.ini.default' already in place.
