But that's going slowly.Has anyone else tackled this yet? Are the Mac Python sources available?Bob, have you done anything with this since the spring? Can you perhaps enlighten us with what you know regarding the task queue to pull this off?I have no plans or interest in doing the work to support little endian until I have a little endian machine. That's not going to happen unless someone gives me one, or Apple comes out with a little endian powerbook.
I do have access to a little endian machine at work, but because changing Python to support fat binaries is likely to be very boring for the most part I won't work on it as well unless I'd actually have a good reason to do so.
What you could do is building a native python on PPC, a native python on x86 and then merge the two. This would give you most of the functionality you're after.
If I'd work on fat binary support I'd do it in this order: 1) Somehow automate the two builds + merge 2) Modify distutils to build fat binaries3) Try to factor out all CPU-dependent autoconf stuff, such as by adding a py-cpuinfo.h
If you go for step 2 it might be useful to add building against SDKs as well (10.3 or even 10.2 for PPC and 10.4 for x86). Step 1 is easy, step 3 is easy as well (except for the "get the patch merged into Python CVS" part), step 2 is a lot harder.
