timeline for python2.6 in Chimera on OS X?
On OS X 10.6 (Snow Leopard) the default python version is 2.6. Python 2.5 is also available, but is kind of hacky. Part of the problem is that python2.5 doesn't compile as a framework. Another (possibly related) problem is that Tk depends on Carbon (at least the "native" version does) and Carbon no longer exists in 10.6. See http://bugs.python.org/issue6802 for details. I'm relying both on MacPorts and Chimera for dependencies, so I need them to be in sync (for example, boost.python built against python2.6 won't work with Chimera's python2.5). I could try to hack around the python2.5 problems on 10.6, but it'd be nice if I could drop in python2.6 in Chimera and everything would "just work." This is unlikely going to be the case, so I was wondering if the Chimera team already has a switch to python2.6 planned in its development roadmap. -- Mark

For the upcoming chimera 1.4 release, chimera is staying with Python 2.5. After that, we plan to update our Python to 2.6 or 3.1 and Tcl/Tk to 8.6 for the daily builds. Tk 8.6 is currently in beta and uses Cocoa instead instead of Carbon internally. Once Tk uses Cocoa, we will be able to do 64-bit builds for the Mac. This 32-bit versus 64-bit problem might be another thing that preventing you from combining MacPorts and Chimera. Do you need anything besides boost.python from MacPorts? We are already compiling boost.python 1.34.1 in the chimera builds and could make that available as a separate download. - Greg P.S. The Aqua version of chimera uses a Python 2.5 framework, so not sure where you read it didn't compile. The X11 chimera of chimera doesn't use frameworks to be more like the Linux X11 version.

Argh, I hadn't thought of the 32bit vs. 64 bit problem. I'll need to make universal binaries...

I also use boost.serialization, boost.mpi, hdf5 (with szip support), fftw3. I could compile Boost "by hand" and force it to use python2.5 (either the framework in /System or the one in Chimera).

You're probably compiling the framework on 10.5. On 10.6 it doesn't compile; see http://bugs.python.org/issue6802. -- Mark
