gmake 中的变量赋值似乎已损坏？

Question

我知道这一定是我做错了，但我迷失了。

我有一个 makefile，其中一部分看起来像

COMMON_CFLAGS = $(DMFLAGS) \
-I$(subst ;, -I,$(DRV_INCLUDE_LIST)) \
-I$(subst ;, -I,$(SEN_INCLUDE_LIST)) \
-I$(subst ;, -I,$(DRV_EXT_INCLUDE_LIST)) \
-D$(BAMBOO_EXT_EXPAT_PARSER_ENTROPY_CONFIG)

# Add the license module dependencies. We only link to the release version of the license module.
ifeq ($(RTU),1)
COMMON_CFLAGS += -I$(SIMBALICENSE_DIR)/Include -DDO_LICENSE_CHECK
endif

$(warning In Makefile_FLAGS.mak: $${COMMON_CFLAGS}= '${COMMON_CFLAGS}')


##--------------------------------------------------------------------------------------------------
## There are no platform specific FLAGS for this project except Solaris.
##--------------------------------------------------------------------------------------------------
CFLAGS = $(COMMON_CFLAGS) -DHAVE_MEMMOVE -DOPENSSL_API_COMPAT=0x10000000L

$(warning In Makefile_FLAGS.mak: $${CFLAGS}= '${CFLAGS}')

我添加了

$(warning)

调用来尝试和调试似乎

CFLAGS

未正确设置的问题。

我在运行构建时得到的输出看起来像

嗯，什么？难道不应该保证

CFLAGS

在

$(COMMON_CFLAGS)

行之后有

-DHAVE_MEMMOVE -DOPENSSL_API_COMPAT=0x10000000L

作为前缀，

CFLAGS = $(COMMON_CFLAGS) -DHAVE_MEMMOVE -DOPENSSL_API_COMPAT=0x10000000L

作为后缀吗？

Answer 1

我刚刚意识到 makefile 是通过命令行参数来调用的

"CFLAGS=-O3 -fPIC -m32"

，这解释了它......
