To cut a long story short, I was trying to compile and get ImageMagick working on my Mac running Snow Leopard.

One thing led to another and now I am stuck with the following error message when I try to start Apache, which I have tried unsuccessfully to fix for the last two days:

httpd: Syntax error on line 116 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/libphp5.so into server: dlopen(/usr/libexec/apache2/libphp5.so, 10): Library not loaded: /usr/local/lib/libjpeg.8.dylib\n Referenced from: /usr/libexec/apache2/libphp5.so\n Reason: Incompatible library version: libphp5.so requires version 13.0.0 or later, but libjpeg.8.dylib provides version 9.0.0

My Apache Version is as follows:

Server version: Apache/2.2.21 (Unix) Server built: Dec 5 2011 20:56:38

Output of my Apache error log is as follows:

[Tue Jan 15 20:46:36 2013] [notice] Digest: done [Tue Jan 15 20:46:36 2013] [notice] Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8r DAV/2 PHP/5.2.5 configured -- resuming normal operations [Tue Jan 15 20:46:41 2013] [notice] child pid 34820 exit signal Segmentation fault (11)

Any point in the right direction would be much appreciated.


Somehow posting the issue to StackOverflow got me thinking on a different track and enabled me to fix it. It turns out when I was building PHP it wasn't generating the libphp5.so file. Here's how I solved that:

  1. First find the apxs path by typing this:

    which apxs 
  2. Then build PHP like so (replace /usr/sbin/apxs with the result from which apxs in step #1:

    ./configure --with-apxs2=/usr/sbin/apxs
    sudo make install
