mod_wsgi-1.1_0 compiles against Python 2.4 but links against system Python 2.5

[francis@…]

After installing mod_wsgi (and adding a LoadModule for it to httpd.conf) I get warnings in the apache error_log about Python versions:

I am using OS X 10.5.6 on Intel.

"otool" shows that mod_wsgi.so is indeed linked against Python 2.5:

# otool -L /opt/local/apache2/modules/mod_wsgi.so 
/opt/local/apache2/modules/mod_wsgi.so:
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.3)
	/System/Library/Frameworks/Python.framework/Versions/2.5/Python (compatibility version 2.5.0, current version 2.5.1)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)

Workaround: set up LDFLAGS by hand as follows:

1) port configure mod_wsgi

2) edit /opt/local/var/macports/sources/rsync.macports.org/release/ports/www/mod_wsgi/work/mod_wsgi-1.1/Makefile and change the line

LDFLAGS = -framework Python -u _PyMac_Error  /opt/local/Library/Frameworks/

to

LDFLAGS = -framework Python -u _PyMac_Error  -F/opt/local/Library/Frameworks/

i.e. add "-F" before "/opt/local/Library/Frameworks/"

3) port install mod_wsgi

Do you have python_select set to a macports python?

[francis@…]

Yes, python_select is set to python24:

francis@spaceman ~ $ python_select -s
python24

[blb@…]

What version of the python24 port do you have installed? A fix for it (in r48185, bring python24 to 2.4.6_1) which improved linking against it, and it may fix your issue. You'd need to rebuild mod_wsgi after upgrading python24 if that's the case.

[francis@…]

I have python24 2.4.6_1 installed. I have tried rebuilding mod_wsgi to make sure it has been built against that version of python24, but it still links against the wrong python:

spaceman ~ # port clean mod_wsgi

I see, the configure script is making some framework assumptions that don't work too well with MacPorts' python. Attached is a diff for mod_wsgi which should fix this. Note that an error with python24 was fixed in r48320 which is needed for this to work.

diff to mod_wsgi

[francis@…]

Thanks, that patch works for me (with python24 2.4.6_2).

Cc Me!

[Graham.Dumpleton@…]

Is mod_wsgi 1.1 really the most up to date version of mod_wsgi MacPorts supply?

The latest version of mod_wsgi available at this time is mod_wsgi 2.3 with 2.4 and 3.0 not far away.

You should really be deprecating your 1.1 port and marking it not for use.

[blb@…]

Applied in r48610 (maintainer timeout).

sorry guys, have been on vacation...

[andreas@…]

Nothing to do with the bug report but here's how I installed mod_wsgi 2.4 with macports python 2.6 and macports apache2:

I guess it would work with macports python 2.5 aswell.
