Description:
------------
Configuration of APC:

'./configure' \
'--enable-apc' \
'--with-apxs' \
'--with-php-config=/usr/local/php5/bin/php-config' \

Restarting Apache2 (2.0.54) yields the following error:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/php5/lib/php/extensions/no-debug-non-zts-20050922/apc.so' - /usr/local/php5/lib/php/extensions/no-debug-non-zts-20050922/apc.so: undefined symbol: OnUpdateBool in Unknown on line 0

http://cvs.php.net/viewvc.cgi/ZendEngine2/zend_ini.h?annotate=1.40

Tells me that OnUpdateBool has been in zend_ini.h since version 1.1

I can see this happening if your PHP header files you built APC against are out of synch with the version of PHP you are loading it into.

OnUpdateBool is in '/usr/local/php5/include/php/Zend/zend_ini.h':
ZEND_API ZEND_INI_MH(OnUpdateBool);

According to 'php-config' and './configure', this file should have been used:

$ php-config --includes
-I/usr/local/php5/include/php -I/usr/local/php5/include/php/main -I/usr/local/php5/include/php/TSRM -I/usr/local/php5/include/php/Zend -I/usr/local/php5/include/php/ext

checking for PHP includes... -I/usr/local/php5/include/php -I/usr/local/php5/include/php/main -I/usr/local/php5/include/php/TSRM -I/usr/local/php5/include/ph
p/Zend -I/usr/local/php5/include/php/ext
checking for PHP extension directory... /usr/local/php5/lib/php/extensions/no-debug-non-zts-20050922
checking for PHP installed headers prefix... /usr/local/php5/include/php

However, I noticed PHP itself was configured with the option '--enable-versioning', which is marked as 'experts only'. Removing this and recompiling PHP and APC helped, APC works now.

Thank you for your help.

Issue with php build - not an APC bug.
