I didn't look through your errors, but I think that the consensus (or, perhaps, the advice from Apple) is that you not use gcc 4 as it currently stands, particularly not for the OS and extensions. In the first place, the version of gcc 4 that Apple shipped predates the "final" gcc4 support for C++, so its support of that language is not great (a number of important bugs were fixed for the final release). In the second, most of the open source components of Mac OS X 10.4 were compiled with gcc 3.3, including the kernel. If you are just building with command-line tools, you can use "scc_select" to set the default compiler. This email sent to site_archiver(a)lists.apple.com

In trying to figure this out, I found a definition for SUB_ABSOLUTETIME in libkern/libkern/OSBase.h, inside my unpacked kernel archive. I'm still getting errors, despite having the headers available locally and included from AppleADBKeyboard.cpp. I'd be grateful if someone could point me to a general doc or somesuch that talks about the desired layout for source and headers for kernel builds and for builds that depend on things defined in the kernel source package.

I just searched developer.apple.com for "kauth" and didn't turn up much, but there looks to be some meat in sys/kauth.h. Therefore, given that the mds process detects whenever any file on the entire filesystem is written, it seems doubtful that it uses kqueue. This email sent to site_archiver(a)lists.apple.com
