I've been going down the pre-doomed path of trying to build Libc
391.4.1
from 8G1454 (10.4.5 x86), and come across a discrepancy with
xnu-792.6.61 (10.4.5 ppc) and my existing xnu 792.6.61 based 10.4.5 ppc
system. Specifically, <sys/sysctl.h> in the source is missing
KERN_PROCNAME, whereas <sys/sysctl.h> on my installed 10.4.5 ppc
w/xcode 2.2.1 system has it. Poking around, no ppc sources from
10.3.9-10.4.5 have that macro defined, yet there it is, on my system.
I'm going to go wildly out on a limb here and suppose the headers
from xcode 2.2.1 include some headers from 10.4.5 x86 xnu, which
has not been released in source form.
That's (mostly) correct. The Xcode 2.2.1 release matches the 10.4.4
(not 10.4.5) release for Intel. Where headers might be different
between 10.4.4/Intel and 10.4.4/PowerPC, Xcode 2.2.1 has the Intel
versions.
Or do we need to go and
rummage around in our xcode 2.2.1 systems and try to extract the
headers we need and try to cobble together some set of headers
that might (possibly, maybe, probably not) work?
Presumably you could build the PowerPC xnu, figure out which headers it
installs, and copy those headers from an Xcode 2.2.1 install....
