Get PHP extension APC not running on Ubuntu 14.04.3 - undefined symbol: php_pcre_exec

  • 772

I installed the PHP extension APC on the server but I get it not running. It gets not listed in phpinfo(). After activating the php error log I get the following error:

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

In phpinfo I don't see any extension for apc. I jsut see that the following files has been added "/etc/php5/apache2/conf.d/20-apcu.ini" which seems to get parsed in addition to php.ini and in the ini file is 

 extension=apcu.so

The apcu.so file has been installed through apt-get and is in

/usr/lib/php5/20121212/apcu.so

/var/www/vhosts/chroot/usr/lib64/php/modules/apcu.so

any hints how this error "undefined symbol: php_pcre_exec" can be solved. Which additional libraries are missing?

  1. Create a php info page

    <?php phpinfo(); ?>

    and then see if /etc/php5/apache2/conf.d/ is included here at

    scan this dir for additional .ini files

    phpinfo

    also the file "/etc/php5/apache2/conf.d/20-apcu.ini" should be listed in the

    Additional .ini files parsed

    if not, you could move the ini file to that directory, or change the directory in the php.ini how-do-i-include-a-php-ini-file-in-another-php-ini-file
