System: Debian Lenny 5.0, DirectAdmin, after successfully update php to 5.2.14 after download and comile from source eaccelerator and test by php -v I got:
This build of “eAccelerator” was compiled for PHP version 5.2.14-0.dotdeb.0. Rebuild it for your PHP version (5.2.14) or download precompiled binaries.
Bad news because actually I`ve PHP in version 5.2.14! After some research I have solutions.
/usr/local/php5/bin/phpize ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php5/bin/php-config make make install
in my case I must move compiled eaccelerator file from /usr/local/php5/lib/php/extensions/no-debug-non-zts-20090626/eaccelerator.so to php extension dir /usr/lib/php5/20060613+lfs/. (update: easier and more logical it is change extension_dir in php.ini)
Have a nice day 🙂
