this 2nd part is no good. "+=" is not the same thing as ":=". might be simpler to do: PF_CPPFLAGS_MARM := $(call cc-option,-marm) PF_CPPFLAGS_THUMB := $(call cc-option,-mthumb -mthumb-interwork) PF_CPPFLAGS_NO_THUMB := $(call cc-option,-mno-thumb-interwork) ifeq ($(CONFIG_SYS_THUMB_BUILD),y) PF_CPPFLAGS_ARM = $(PF_CPPFLAGS_THUMB) else PF_CPPFLAGS_ARM = $(PF_CPPFLAGS_MARM) $(PF_CPPFLAGS_NO_THUMB) endif -mike
