FastCGI on OS/X Leopard

A post for posterity.

OK, so you want to run FastCGI on OS/X 10.5, how does that work? If you’ve just followed the directions and used your usual UNIX skillz, you’ll have dead-ended on this odd error:

httpd: Syntax error on line 115 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/ into server: dlopen(/usr/libexec/apache2/, 10): no suitable image found. Did find:\n\t/usr/libexec/apache2/ mach-o, but wrong architecture

This is the architecture of your DSO not matching the x86_64 architecture of the build shipped with OS/X. So we must build with the correct flags in place.

Here’s the steps from scratch.

curl > mod_fastcgi-2.4.6.tar.gz
tar xvfz mod_fastcgi-2.4.6.tar.gz
cd mod_fastcgi-2.4.6
cp Makefile.AP2 Makefile

Now edit Makefile and change top_dir to /usr/share/httpd and add a line CFLAGS=-arch x86_64.

sudo cp .libs/ /usr/libexec/apache2

Now edit /private/etc/apache2/httpd.conf and add a line LoadModule fastcgi_module libexec/apache2/ Run sudo apachectl restart and you are now loaded. You’ll need to enable FastCGI for your applications as described in the documentation.
