Hi Mike, As I said before, I know nothing about sparc, but are these the right headers ? If you're going to build a 64-bit kernel then that would need different definitions of things from the 32-bit userspace, so _maybe_ you need two sets of headers (one for when you build a 64-bit toolchain, another for the regular 32-bit userspace). I'm sort of thinking you've got to do some bi-arch stuff. Take a look at Ryan's Cross-Lfs scripts (http://www.linuxfromscratch.org/~ryan/scripts/cross-lfs) - use the latest version of hte scripts. > Here is the end result of attempting to compile with CFLAGS and CXXFLAGS > unset, using the Sparc64 kernel headers, and running configure as shown > in Chapter 6 for Glibc.

Hopefully, finding this ebuild script will drop you into a gentoo portage tree. glibc is in sys-libs/, binutils and gcc are in sys-devel/, and I can see that 64-bit compilers for the kernel (egcs64-sparc, gcc-sparc64) are separated. It looks as if they have some experience with sparc, so I suggest seeing what you can learn from the flags they are using. HTH.
