There is a way though I'd not call it clean. Here is an extract from the Makefile I am using for separately-distributed modules. It should work with kernels 2.0 to 2.4, all supported architectures.
include $(KERNEL_SOURCE)/.config
CPPFLAGS := -DMODULE -D__KERNEL__ -nostdinc -I$(KERNEL_SOURCE)/include CPPFLAGS += -I$(shell gcc -print-file-name=include) CFLAGS := $(CPPFLAGS) -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer AFLAGS := -D__ASSEMBLY__ $(CPPFLAGS)
# For older kernels. ifneq (,$(strip $(shell grep '^[ ]*SMP[ ]*:\?=[ ]*[^ ]' $(KERNEL_SOURCE)/Makefile))) CONFIG_SMP=y endif ifdef CONFIG_SMP CFLAGS += -D__SMP__ AFLAGS += -D__SMP__ endif
include $(KERNEL_SOURCE)/arch/$(ARCH)/Makefile
CFLAGS += $(shell if $(CC) -fno-strict-aliasing -S -o /dev/null -xc /dev/null >/dev/null 2>&1; then echo "-fno-strict-aliasing"; fi) - 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/
