linux - Linux makefile 中的 OR 条件

Question

ifeq (ABC,$(strip $(TYPE)))
include src1.mk
else ifeq (EFG,$(strip $(TYPE)))
include src1.mk
else
include src2.mk

如何结合以上两个条件。

我试过了

ifeq ($(TYPE),$(filter $(TYPE),ABC EFG))
include src1.mk
else
include src2.mk

但它的行为不正确，即使 TYPE 不是 ABC 或 EFG，它也会进入 if case。

Answer 1

ifneq ($(filter $(TYPE),ABC EFG),)

我有以下内容:

ifneq ($(filter $(TYPE),ABC EFG),)
 $(info TYPE is in ABC EFG)
endif

ifeq ($(TYPE),$(filter $(TYPE),ABC EFG))
 $(info Ruchis test passed)
endif

all:
        @# do nothing

然后我就跑了

~/tmp> make TYPE=ABC
TYPE is in ABC EFG
Ruchis test passed

~/tmp> make TYPE=EFG
TYPE is in ABC EFG
Ruchis test passed

~/tmp> make TYPE=HIJ

~/tmp> make TYPE=
Ruchis test passed

如果 $(TYPE) 为空，您的测试会给出误报。
