I belive the problem is that you did not compile your cross-compiler correctly: $ ppc_7xx-cpp -dM /tmp/foo.h | grep pc #define __powerpc__ 1 #define __powerpc 1 #define powerpc 1 Make sure you do --target=powerpc-foo-linux when configuring gcc. -- Tom Rini http://gate.crashing.org/~trini/ ** Sent via the linuxppc-embedded mail list.
