I hope this is to the right list... the recent discussion of
retiring ppc arch encouraged me to ask.
Ultimately, I'm trying to build a native PPC 405 compiler (i.e
Canadian cross). I've got a crosstool's generated cross-compiler
and I have glibc and a native bintools on my 405 root filesystem.
What I'd like to do is:
make ARCH=ppc headers_check
make ARCH=ppc INSTALL_HDR_PATH=dest headers_install
but that's not supported in the ppc tree.
So my question is, can I just ...
make ARCH=powerpc headers_check
make ARCH=powerpc INSTALL_HDR_PATH=dest headers_install
and then switch to ppc when I build the kernel?
I suspect it will work but just don't know if there is a
subtle difference that will come back to haunt me at
run-time.
Any advice would be greatly appreciated!
Ron

Yes, that is exactly what you are meant to do. The headers
need to be compatible, otherwise we would have bigger problems
running user space programs built against an older kernel
on current machines.
