简化构建多个可执行文件的Android.mk文件

Question

我正在为Android构建一些硬件测试。我有一个接一个建立这些可执行文件的文件Android.mk使用的每个生成文件代码块，如下图所示：

##### shared ##### 
LOCAL_PATH := $(my-dir) 

##### test_number_one ##### 
test_name := test_number_one 
include $(CLEAR_VARS) 
LOCAL_CFLAGS := $(commonCflags) 
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../ 
LOCAL_MODULE_TAGS := optional eng 
LOCAL_SHARED_LIBRARIES := some_library some_other_library 
LOCAL_MODULE := $(test_name) 
LOCAL_SRC_FILES := tests/$(test_name)/$(test_name).c 
include $(BUILD_EXECUTABLE) 


##### test_number_two ##### 
test_name := test_number_two 
include $(CLEAR_VARS) 
LOCAL_CFLAGS := $(commonCflags) 
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../ 
LOCAL_MODULE_TAGS := optional eng 
LOCAL_SHARED_LIBRARIES := some_library some_other_library 
LOCAL_MODULE := $(test_name) 
LOCAL_SRC_FILES := tests/$(test_name)/$(test_name).c 
include $(BUILD_EXECUTABLE) 

正如你可以看到，大多数代码的重复每个测试（在include $(CLEAR_VARS)和include $(CLEAR_VARS)之间）。我想简化这个，使我有一个测试名称列表和一段为每个“调用”的makefile代码。我不在乎这些代码是否必须拆分成另一个文件。下面是一些蟒蛇式的伪代码来证明什么，我去为：在Android.mk文件

##### shared ##### 
LOCAL_PATH := $(my-dir) 

##### test_number_one ##### 
test_names := test_number_one test_numer_two 

for each item in test_names: 
    include $(CLEAR_VARS) 
    LOCAL_CFLAGS := $(commonCflags) 
    LOCAL_C_INCLUDES := $(LOCAL_PATH)/../ 
    LOCAL_MODULE_TAGS := optional eng 
    LOCAL_SHARED_LIBRARIES := some_library some_other_library 
    LOCAL_MODULE := $(item) 
    LOCAL_SRC_FILES := tests/$(item)/$(item).c 
    include $(BUILD_EXECUTABLE) 

这可能吗？如何做呢？

你应该能够做到像

define my_add_executable 
    include $(CLEAR_VARS) 
    LOCAL_CFLAGS := $(commonCflags) 
    LOCAL_C_INCLUDES := $(LOCAL_PATH)/../ 
    LOCAL_MODULE_TAGS := optional eng 
    LOCAL_SHARED_LIBRARIES := some_library some_other_library 
    LOCAL_MODULE := $1 
    LOCAL_SRC_FILES := tests/$1/$1.c 
    include $(BUILD_EXECUTABLE) 
endef 

test_names := test_number_one test_numer_two 
$(foreach item,$(test_names),$(eval $(call my_add_executable,$(item)))) 

我们也有类似的建筑在我们的项目中包括多个预建库。
