PHP Startup: Unable to load dynamic library '/var/www/vhosts/chroot/usr/lib64/php/modules/apcu.so: undefined symbol: php_pcre_exec in Unknown on line 0
I am using the following versions Ubuntu 14.04.3 / PHP 5.6.13 / Apache 2.4.7
The installation has been made with:
sudo apt-get install php-apc

The apcu.so file has been installed through apt-get and is in
any hints how this error "undefined symbol: php_pcre_exec" can be solved. Which additional libraries are missing?
