PHP 5.3.3 compiled on Mac OS X 10.6 - using /usr/lib when trying to start Apache... rather than /opt/local/lib specified when PHP was configured.

Why is it trying to load from /usr/lib when I specified in my configure not to?

httpd: Syntax error on line 115 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/ into server: dlopen(/usr/libexec/apache2/, 10): Library not loaded: /opt/local/lib/libiconv.2.dylib\n Referenced from: /usr/libexec/apache2/\n Reason: Incompatible library version: requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0

The error message above refers to /opt/local/lib which when I run:

otool -LD /opt/local/lib/libiconv.2.dylib 


/opt/local/lib/libiconv.2.dylib: /opt/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0)

It shows that the version is different than what httpd is erring out as.

I have a feeling I need to recompile Apache using newer libraries, but the error message still doesn't make too much sense to me.

How do you start the apache server? – Mark Jan 18 '11 at 16:54
/usr/sbin/apachectl -k [graceful|restart|stop...] Apache is running currently, but when I attempt to stop/start/restart (etc.) it the error above kicks out – Anthony Jan 18 '11 at 18:00

As you have files in /opt/local I assume you are using MacPorts. In this case PHP will have been compiled against Apache in MacPorts (in /opt/local/bin), and you will need to configure and start that one, not the default Apple supplied one.

I've set my path to use use the PHP binary in /opt/local/bin which is fine. PHP cli is working well, but should I recompile apache as well? Sorry guys, by no means am I a server admin, just trying to learn a bit here. – Anthony Jan 18 '11 at 21:03
because you havecompiled php against the macports apache and not the one in /usr/sbin and they have different binary APIs – Mark Jan 19 '11 at 6:30
