Everything had been worked perfectly with APC and Exponential on my Debian Etch amd64 until I issued:

pecl upgrade apc

which upgraded to APC-3.0.16 and created a new library in
/usr/lib/php5/20060613/apc.so

and replaced the previous
/usr/lib/php4/20050606/apc.so [APC-3.0.14 - shoot, I don't have a backup...]

The problem must be that I installed php5 [cgi] after php4 and apc...

If I move the new apc.so to the correct extension_dir, Apache2 can't load it and says:

PHP Warning: Unknown(): Unable to load dynamic library '/usr/lib/php4/20050606/apc.so' - /usr/lib/php4/20050606/apc.so: undefined symbol: zend_opcode_handlers in Unknown on line 0

How can I recompile apc for just PHP/4.4.4-8+etch4 and give Exponential a cache again?

Regards, :DTM.

Quite simple indeed... remove php5, compile APC for php4, reinstall php5...

pecl uninstall apc
aptitude remove php5-cgi
aptitude remove php5-dev php5-mysql php5-gd php5-mcrypt

pecl install apc
aptitude install php5-cgi
aptitude install php5-dev php5-mysql php5-gd php5-mcrypt

Is there a better solution [maybe a conf. switch to compile for either php4 or php5, or both]?

Good nite, :DTM.
