I'm running Ubuntu 8.04 on this server. I had PHP 5.2 installed via the package manager. I removed it to install PHP 5.3.1 by hand. I built the packages like so
./configure --prefix=/opt/php --with-mysql --with-curl=/usr/bin --with-apxs2=/usr/bin/apxs2 make make install
This installed PHP 5.3.1 in /opt/php/
$ php -v PHP 5.3.1 (cli) (built: Dec 7 2009 10:51:14) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies
However, when I try to start Apache I get this.
# /etc/init.d/apache2 restart * Restarting web server apache2 apache2: Syntax error on line 185 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/php5.load: Cannot load /usr/lib/apache2/modules/libphp5.so into server: /usr/lib/apache2/modules/libphp5.so: undefined symbol: OnUpdateLong [fail]
Any ideas what's causing this error? All the references I can see have to do with building php5 packages for php4 or the like. PHP4 has never been installed on this machine.
