Compile APC in PHP 5.2

Hello, I try to get APC working for a compiled PHP 5.2.17. On this Ubuntu, we have an PHP 5.3 installed with APT-GET and a PHP 5.2 as CGI module compiled with make etc. In the PHP 5.3 I got APC running in phpinfo, but not in PHP 5.2, what we have to do to get work it? I use this http://de2.php.net/manual/de/install.pecl.static.php but if I use the configure with ./configure --prefix=/opt/php5.2 --with-config-file-path=/opt/php5.2 --with-mysqli --with-mysql --with-pdo-mysql --with-curl --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --with-freetype-dir=/usr --enable-cli --enable-fastcgi --enable-discard-path --enable-force-cgi-redirect --enable-mbstring --with-bz2 --enable-gd-native-ttf --enable-calendar --with-gmp --enable-bcmath --with-xpm-dir=/usr --enable-soap --with-openssl --with-zlib --with-apc There are only errors in the configure and it seems, that buildconf destroy the configure file. I try also http://www.linuxask.com/questions/how-to-compile-apc-module-for-php but if I add extension=apc.so and restart, it will not be shown in phpinfo. Best regards Alexander
