A while ago. On 2002/09/13 I posted to this list but with no success. I found the problem in the main Makefile: --------------- @@ -261,7 +262,7 @@ # 'kbuild_2_4_nostdinc :=' or -I/usr/include for kernel code and you are not UML # then your code is broken! KAO. -kbuild_2_4_nostdinc := -nostdinc -iwithprefix include +kbuild_2_4_nostdinc := -nostdinc $(shell $(CC) -print-search-dirs | sed -ne 's/install: \(.*\)/-I \1include/gp') export kbuild_2_4_nostdinc export CPPFLAGS CFLAGS CFLAGS_KERNEL AFLAGS AFLAGS_KERNEL --------------- I have no idea why... :o( Cheers, Steven ** Sent via the linuxppc-embedded mail list.
