If you try to install PHP APC 3.1.5 through PHP PEAR and encounter errors regarding phpize or the following:
/usr/include/php5/ext/pcre/php_pcre.h:29:18: error: pcre.h: No such file or directory
…well don’t worry. You’re missing a few components. For phpize, you’ll need the php5-dev that you can fetch from Ubuntu. For the php_prce.h error, you’ll need pcre3-dev package which is essentially Perl 5 Compatible Regular Expression Library – development files.
Perform the following and install PHP APC using PECL again:
sudo apt-get install libpcre3-dev php5-dev sudo pecl install apc-3.1.5
And it’s done:
Build process completed successfully Installing '/usr/lib/php5/20090626+lfs/apc.so' install ok: channel://pecl.php.net/APC-3.1.5 configuration option "php_ini" is not set to php.ini location You should add "extension=apc.so" to php.ini
This is tested against Ubuntu 10.04 as well as Ubuntu 10.10 environments.
You can add it to /etc/php5/conf.d/apc.ini by:
Add in the following codes:
extension=apc.so apc.enabled=1 apc.shm_segments=1 apc.shm_size=32M apc.cache_by_default=1 apc.stat=1 apc.rfc1867=1 //For Drupal upload progress. apc.stat=7200 //2 hours
