Again with 'symbol not found' on Leopard...
radioflyer
Leopard 10.5.6. I'm using svn checkouts of both modules. I'm using
Python 2.6.1.
With the exact same setup on both machines, I'm succeeding on my
MacBookPro(intel) and failing in my G5 Tower(ppc)
Here's the config test error on the ppc machine:
/private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/
mod_wsgi.so into server: dlopen(/usr/libexec/apache2/mod_wsgi.so, 10):

Referenced from: /usr/libexec/apache2/mod_wsgi.so
Expected in: dynamic lookup
httpd.conf line:

and:

The output above is exactly the same when I am trying mod_python.
Here's configure output:

The binary seems to have the correct architectures when I run 'file'
on it, but make shows a warning in the last line that looks ominous.
Any solution obvious?

Did you install this Python version yourself, or are you using MacPorts Python?

This is the package installer from the Python site. I got it here:
http://www.python.org/download/releases/2.6.
It installs in this path: /Library/Frameworks/Python.framework/
Versions/2.6
I used the same installer for both of my machines. As I mentioned, all
is well on my intel mac but no joy on my ppc G5. My goal is to get
mod_wsgi working on a ppc running Leopard Server at my school so I can
deploy a Django app.

Can you send output from running:
file /Library/Frameworks/Python.framework/Python
The above to me indicates that that Python framework installation does
not actually have all architectures compiled into it.

If that installer is officially supplied by PSF, then a bug should be
lodged then at bugs.python.org over the fact that they are
distributing an installer which will not work on 64 bit MacOS X
platforms where framework is embedded into a 64 bit application such
as the version of Apache supplied by Apple. Thus, not usable with
mod_python or mod_wsgi.
What it looks like you will need to do is install Python 2.6 from
source code. I believe the configure options should be:
./configure --prefix=/usr/local/python-2.6
--enable-framework=/usr/local/python-2.6/frameworks
--enable-universalsdk=/ MACOSX_DEPLOYMENT_TARGET=10.5
--with-universal-archs=all
The only other option you have is to force Apache to run as 32 bit
instead of 64 bit. For that, see documentation and comments in:
http://code.google.com/p/modwsgi/wiki/InstallationOnMacOSX

BTW, you might just be better off installing your own copy of Apache
from source. This will install as 32 bit and not 64 bit and so that
Python 2.6 version will then work fine.
The benefits of running 32 bit are that you have less problems with
third party C extension modules and you don't have to perform hacks to
also get them installed with 64 bit architecture objects. The Apple
Python version understand extra environment variables which will force
Python extensions to install with all architectures, but the PSF
version probably doesn't and so it would be necessary to hack
makefiles/setup.py files to add in special arch flags.

was hoping to be able to use the admin interface in Leopard Server to
manage Apache to some extent, and I think I will lose that if I
compile from source. I'll have to investigate that.
You've gotten me moving again though. Thanks again.

First off then, just try what was in comment at end of that wiki page
I emailed. Quoting it here.
"""I was able to force apache on leopard to run in 32-bit mode as follows.
in /System/Library/LaunchDaemons/org.apache.httpd.plist add these
three arguments the start of the <ProgramArguments> array:
<string>/usr/bin/arch</string> <string>-arch</string> <string>i386</string>
the resulting apache command line looks like this:
/usr/bin/arch -arch i386 /usr/sbin/httpd -D FOREGROUND"""
Just be aware that on OS updates, this plist file is likely to be
replaced if Apache was changed.

I decided to start by seeing if building Python from source would make
a difference. After a couple tries I got it installed using:
./configure
--enable-framework=/Library/Frameworks
--enable-universalsdk=/ MACOSX_DEPLOYMENT_TARGET=10.5
--with-universal-archs=all
This put everything in the same place as the Python installer package
and gave me a working Python2.6.1
This appears to have fixed things so that both mod_python and mod_wsgi
install and run properly. So, for now, no need to build or thin
Apache. Next step is to learn how to get my Django apps to use
mod_wsgi.
Thanks again for all your help and patience with this.
