Makefile ifeq logical or

Question

How do you perform a logical OR using make\'s ifeq operator?

e.g., I have (simplified):

ifeq ($(GCC_MINOR), 4)
    CFLAGS += -fno-strict         


        

Answer 1

I don't think there's a concise, sensible way to do that, but there are verbose, sensible ways (such as Foo Bah's) and concise, pathological ways, such as

ifneq (,$(findstring $(GCC_MINOR),4-5))
    CFLAGS += -fno-strict-overflow
endif

(which will execute the command provided that the string $(GCC_MINOR) appears inside the string 4-5).
