I'm hoping to run my webapp in Apache, but it seems like I can't
import ctypes in my code.
I wrote this trivial wsgi app to short the problem:
def application(environ, start_response):
import ctypes # this crashes
status = '200 OK'
output = 'Hello World!'
response_headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
Then I set up this virtual host:
<VirtualHost *:80>
ServerName pitz.sprout.tplus1.com
ServerAdmin webmas...@localhost
DocumentRoot /home/matt/checkouts/pitz/pitz/static
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel info
CustomLog /var/log/apache2/pitz-access.log combined
ErrorLog /var/log/apache2/pitz-error.log
ServerSignature On
<Directory /home/matt/checkoutz/pitz/apache-nonsense>
Order allow,deny
Allow from all
</Directory>
WSGIProcessGroup pitz
WSGIApplicationGroup %{GLOBAL}
WSGIScriptAlias / /home/matt/checkouts/pitz/apache-nonsense/
myapp.wsgi
RewriteEngine on
RewriteRule ^/static/(.*) /home/matt/checkouts/pitz/pitz/static/$1
[last]
RewriteRule ^/favicon.ico /home/matt/checkouts/pitz/pitz/static/
favicon.ico [last]
</VirtualHost>
And I have this stuff too:
WSGIPythonHome /home/matt/.virtualenvs/pitz
WSGIPythonPath /home/matt/.virtualenvs/pitz/lib/python2.6/site-
packages
WSGIDaemonProcess pitz processes=1 threads=10 display-name=%{GROUP}
When I restart apache, and then hit http://pitz.sprout.tplus1.com/, I
get a 500 back, and this error is in my errors log file:

I'm running ubuntu 10.0.4 LTS, I installed the stock apache2:
$ apache2 -version
Server version: Apache/2.2.14 (Ubuntu)
Server built: Nov 18 2010 21:17:19
The mod_wsgi version I'm running is this 2.8 (it's the one I got from
ubuntu).
I just noticed you're up to version 3.3 -- maybe this problem has
already been fixed, or maybe there's something wrong with my
configuration. Anyhow, I could really use a little help.
