Re: [modwsgi] OSX 10.8.2 setup woes

[Graham Dumpleton]

Possibly because your Apache is 32 bit and not 64 bit.

Use the 'file' command to work out what architectures are compiled into Apache, Python and mod_wsgi.so.

While the install process looked fine, I get the following error when I try to load wsgi in apache:

Libraries have been installed in:

   /usr/libexec/apache2

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR'

flag during linking and do at least one of the following:

   - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable

     during execution

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.

----------------------------------------------------------------------

chmod 755 /usr/libexec/apache2/mod_wsgi.so

Then I edited /usr/local/zend/apache2/conf/httpd.conf :

...

# LoadModule foo_module modules/mod_foo.so

#

LoadModule wsgi_module /usr/libexec/apache2/mod_wsgi.so

...

Running the command at the top of now generates the error. 

Python version info:

>>> import sys

>>> sys.version

'2.7.3 (default, Nov 30 2012, 10:51:01) \n[GCC 4.2.1 Compatible Apple Clang 4.1 ((tags/Apple/clang-421.11.66))]'

>>> sys.maxsize

9223372036854775807

(That's 2^63 +1, confirming that I'm running it in 64-bit mode)

Incidentally, brew install mod_wsgi gives "No available formula"

I spent most of this morning and yesterday afternoon googling and trying to get this to work -- any help you can give would be greatly appreciated!

Thanks! Yeah, looks like that was it. Still having trouble getting apache to recompile with mod_rewrite, but that's a different story.
