I've downloaded memcache-2.2.6 and when i run:
phpize && ./configure --enable-memcache && make
I get:
Configuring for:
PHP Api Version: 20090626
Zend Module Api No: 20090626
Zend Extension Api No: 220090626
This is correct but after configure, make and adding the module to php.ini i get:
PHP Warning: PHP Startup: memcache: Unable to initialize module
Module compiled with module API=20060613
PHP compiled with module API=20090626
Edit: The php its not from the debian package, its a manually php 5.3.8 install
Thanks
