Seen it to - but were busy with other stuff. If you do a $ make V=2 Then you will notice that kbuild tells you that the .o files are built because they are not listed in $(targets). Reading the commonts in scripts/Kbuild.include it says: "this is most likely a bug in your kbuild file". So I did the following and it cured it: [PATCH] x86: do not recompile boot for each build Signed-off-by: Sam Ravnborg <[EMAIL PROTECTED]> --- diff --git a/arch/i386/boot/Makefile b/arch/i386/boot/Makefile index 08678a0..93386a4 100644 --- a/arch/i386/boot/Makefile +++ b/arch/i386/boot/Makefile @@ -39,7 +39,7 @@ setup-y += printf.o string.o tty.o video.o version.o voyager.o setup-y += video-vga.o setup-y += video-vesa.o setup-y += video-bios.o - +targets += $(setup-y) hostprogs-y := tools/build HOSTCFLAGS_build.o := $(LINUXINCLUDE) ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
