So what is setting AS in the Makefile good for then? And how can I force the build process to use /usr/x86_64/bin/x86_64-linux-as rather than /usr/bin/as? Also, isn't it a bug for the Makefile not to pass -m64 if I specify ARCH=x86_64? If I don't change the CFLAGS I get: $ make ARCH=x86_64 CHK include/linux/version.h CC arch/x86_64/kernel/asm-offsets.s arch/x86_64/kernel/asm-offsets.c:1: error: code model 'kernel' not supported in the 32 bit mode make[1]: *** [arch/x86_64/kernel/asm-offsets.s] Error 1 make: *** [prepare0] Error 2 Lee - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
