Hi,

I've just pushed out a new beta release for PyObjC 2.2. This version should install without problems using "easy_install pyobjc==2.2b2", and fixes some other smallish issues as well. Support for OSX 10.4 is still fairly minimal: pyobjc-core and a number of framework wrappers do build on Tiger, but there are a lot of test failures (although a large subset of those are caused by issues in the test framework). Support for OSX 10.6 is non-existant for now due to the obvious reason ;-)

You have non-universal libraries in /usr/local, but I don't understand why this is a problem because that library shouldn't be used at all. What's even more odd is that python tries to compile at all, there are binary eggs available for python2.6.

I'm not quite sure what to make of this response. It seems to me that if a Python library is trying to find a PPC binary on an Intel machine that's a bug in the Python library. Also it's looking in the MacOSX10.4u.sdk directory, but this machine is running 10.5 (. 7), which seems like another bug.

The compiler isn't that smart. If the linker looks for a library and stops at the first filename that matches without looking if it is for the right architecture. That means that if you happen to have a PPC library in /usr/local/lib and the compiler was actually looking for an intel one the search stops at the PPC library and you get a link error. If you have installed Python using the installer from the python.org site the situation is slightly more complicated: that installs a universal binary, which is a fat binary that contains both intel and ppc versions of the code. This means that all libraries that get linked into extensions must also be universal binaries and if they aren't you'll get link errors.

So... is this a bug, or am I doing something stupid? If it's a bug, am I the only person encountering it? Can I do anything to help fix it?

Can you manually download the source archive of pyobjc-framework- ScreenSaver from pypi.python.org and sent me the result of "python2.6 setup.py install. I'd also like to see the output of "file /usr/local/ lib/libTIFF.dylib", "python2.6 -c 'import distutils.util; print distutils.util.get_platform()' and 'python2.6 -V'. And finally: how did you install python, from source or using a binary installer? Please sent this information off-list because it isn't relevant for most readers.
