[Pythonmac-SIG] Using Python 2.5 on Snow Leopard
I was happy to see that Python 2.5 still shipped with SL, but now I'm less happy. I can't seem to compile PIL for Python 2.5 on Snow Leopard. The problem is that when I build and install libjpeg or libpng, it builds 64-bit libraries, but Python 2.5 is 32-bit, so the libraries don't work when PIL tries to use them. You get an error message something like this: import _imaging ImportError: dlopen(/Library/Python/2.5/site-packages/PIL/_imaging.so, 2): Symbol not found: _jpeg_resync_to_restart Referenced from: /Library/Python/2.5/site-packages/PIL/_imaging.so Expected in: dynamic lookup Bill ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Everything that builds directly through distutils should know to build all the correct architectures, but dependent projects that use standard Makefiles may need to be told to compile 32-bit. Though I haven't tried to build PIL myself, I have built libjpeg and libpng before, and setting CC while running configure as suggested by Brad did work for me. This is an unfortunate side-effect of the transition to full 64-bit computing in Mac OS X, and trying to maintain 32-bit compatibility at the same time. -- Edward Moy Apple Inc. e...@apple.com ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Brad Thanks, Brad, I've tried this. It does build the .a files multi-platform, but not the dylib files. And some libraries, like libpng, use -M switches which conflict with multiple architecture flags on the compile line.

Adding the 64 bit lib wouldn't hurt, but it wouldn't' help, either, unless you want to use it with other things that need it. You may also simply be able to use a binary of PIL. There is this one here: http://pythonmac.org/packages/py25-fat/index.html Which is for the python.org 2.5, but you may be able hand-copy some stuff over. I did set up a build to PIL, using macports to build libjpeg and libpng. They build well using the universal variant on a 10.5 Intel system. I'm not sure what macports is building on SL, but it's worth checking out. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

Yes, both 2.5 and 2.6 are available on SL (as well as enough of 2.3 to
provide embedded support).
Twisted seems to be there:

Re: [Pythonmac-SIG] Using Python 2.5 on Snow Leopard
Yes, 2.6 is there, but I thought I'd try building with 2.5. Now, given the issues with 32/64 bit, I think I'm just going to upgrade the OS X UpLib installation to 64 bits, and just use 2.6. Still haven't got the JPEG support in PIL 1.1.6 working that way, but most of the rest seems to work.
