I agree. I have an entire 10.1.5 partition just for building kexts.

Has anyone else tried to set up a 10.1-capable build environment on 10.2 (or
10.3)? Is there any hope?

The XCode docs imply it can be done in some spots, and that it can't in other spots. I have not so far gotten it to actually work.

Heck, I wouldn't even mind using the 10.1 toolchain if I could just use it under 10.3. But no, they require a live 10.1 system.

Just mirror the 10.1 Kernel.framework headers to someplace within your source base and set up the system header search paths to point to it. Make sure you build with gcc 2.95.2. Kexts don't link against anything (yet), so you don't have to worry about library or framework binaries. [*]

If you want to build 10.2 kexts on 10.3, you'll need to do the same thing, but use GCC 3.1 instead.

Caveat: I've only tried this with IOKit kexts.

* Xcode has an SDK concept wherein Unix people learn that the development tools are distinguishable from operating systems, but this doesn't work for non-native targets (as kexts currently must be) _and_ doesn't seem to be changeable on a per-target basis, which would prevent you from targeting multiple OS versions in the same project.
