This is a handy one-liner for seeing what defines gcc has: echo | powerpc-linux-gcc -E -dM - When I run it with a cross-compiled gcc 2.95.3 *and* 3.2, I see both #define __linux__ 1 #define __powerpc__ 1 The 2.95.3 was compiled with exactly the directions you refer to above. 3.2 was slightly different, but in both cases --target=powerpc-linux . -Hollis ** Sent via the linuxppc-embedded mail list.
