Linux – APC module causing strange error

alternative-php-cachecentos6linuxpeclPHP

When I run
php -v

I get:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/apc.so' – /usr/lib64/php/modules/apc.so: undefined symbol: php_pcre_exec in Unknown on line 0

This isn't my first rodeo. I've setup APC multiple times. This is a MediaTemple Dedicated Virtual 4.0 with Plesk 11. Plesk 11 is the only thing essentially different from the other servers I've set this up on.

I've verified that pcre-devel is installed. I've compiled APC from source as well as used pecl to install it. No difference.

I also tried downgrading to APC 3.0.19, with no love.

First install the pecl package from yum repo and then use the below command to install the apc.

pecl install apc

that's it.

Your custom-compiled PHP should have installed pecl, and configured it properly.

Have you tried running "pecl install apc"?

If your system is not finding pecl, it's probable that you used some funny --prefix when you ./configure'd PHP.

For instance, if you compiled php like this:

$ ./configure --prefix=/foo
$ make
# make install

then you'll either want to get /foo/bin into $PATH, or you could just run

$ /foo/bin/pecl install apc

EDIT: Now I remember: try pecl install apc-beta. Something is screwy with 5.3.3 and non-beta APC. My experience is apc-beta works fine.

CentOS 5.6 – yum update php to 5.2.10

If an even newer PHP is not a problem (PHP 5.3), it is now available for CentOS 5.6.

The packages are named php53 instead of php, and the json module is part of the php53-common package.
