如何输出 android.mk 及 Application.mk 中个变量的值

想知道 android.mk 及 Application.mk 中各变量的值可以通过新建如下两个.mk文件:

• PRINT_ANDROID_VARIABLE.mk
• PRINT_APPLICATION_VARIABLE.mk

包含到android.mk文件中某位置:

1 include $(LOCAL_PATH)\PRINT_ANDROID_VARIABLE.mk
2 include $(LOCAL_PATH)\PRINT_APPLICATION_VARIABLE.mk

文件PRINT_ANDROID_VARIABLE.mk内容如下：

 1 $(warning  CLEAR_VARS = $(CLEAR_VARS))
 2 $(warning  BUILD_SHARED_LIBRARY = $(BUILD_SHARED_LIBRARY))
 3 $(warning  BUILD_STATIC_LIBRARY = $(BUILD_STATIC_LIBRARY))
 4 $(warning  PREBUILT_SHARED_LIBRARY = $(PREBUILT_SHARED_LIBRARY))
 5 $(warning  TARGET_ARCH = $(TARGET_ARCH))
 6 $(warning  TARGET_PLATFORM = $(TARGET_PLATFORM))
 7 $(warning  TARGET_ARCH_ABI = $(TARGET_ARCH_ABI))
 8 $(warning  TARGET_ABI = $(TARGET_ABI))
 9 $(warning  LOCAL_PATH = $(LOCAL_PATH))
10 $(warning  LOCAL_MODULE = $(LOCAL_MODULE))
11 $(warning  LOCAL_MODULE_FILENAME = $(LOCAL_MODULE_FILENAME))
12 $(warning  LOCAL_SRC_FILES = $(LOCAL_SRC_FILES))
13 $(warning  LOCAL_CPP_EXTENSION = $(LOCAL_CPP_EXTENSION))
14 $(warning  LOCAL_C_INCLUDES = $(LOCAL_C_INCLUDES))
15 $(warning  LOCAL_CFLAGS = $(LOCAL_CFLAGS))
16 $(warning  LOCAL_CXXFLAGS = $(LOCAL_CXXFLAGS))
17 $(warning  LOCAL_CPPFLAGS = $(LOCAL_CPPFLAGS))
18 $(warning  LOCAL_STATIC_LIBRARIES = $(LOCAL_STATIC_LIBRARIES))
19 $(warning  LOCAL_SHARED_LIBRARIES = $(LOCAL_SHARED_LIBRARIES))
20 $(warning  LOCAL_WHOLE_STATIC_LIBRARIES = $(LOCAL_WHOLE_STATIC_LIBRARIES))
21 $(warning  LOCAL_LDLIBS = $(LOCAL_LDLIBS))
22 $(warning  LOCAL_LDFLAGS = $(LOCAL_LDFLAGS))
23 $(warning  LOCAL_ALLOW_UNDEFINED_SYMBOLS = $(LOCAL_ALLOW_UNDEFINED_SYMBOLS))
24 $(warning  LOCAL_ARM_MODE = $(LOCAL_ARM_MODE))
25 $(warning  LOCAL_ARM_NEON = $(LOCAL_ARM_NEON))
26 $(warning  LOCAL_DISABLE_NO_EXECUTE = $(LOCAL_DISABLE_NO_EXECUTE))
27 $(warning  LOCAL_DISABLE_RELRO = $(LOCAL_DISABLE_RELRO))
28 $(warning  LOCAL_DISABLE_FORMAT_STRING_CHECKS = $(LOCAL_DISABLE_FORMAT_STRING_CHECKS))
29 $(warning  LOCAL_EXPORT_CFLAGS = $(LOCAL_EXPORT_CFLAGS))
30 $(warning  LOCAL_EXPORT_CPPFLAGS = $(LOCAL_EXPORT_CPPFLAGS))
31 $(warning  LOCAL_EXPORT_C_INCLUDES = $(LOCAL_EXPORT_C_INCLUDES))
32 $(warning  LOCAL_EXPORT_LDFLAGS = $(LOCAL_EXPORT_LDFLAGS))

35 $(warning  LOCAL_THIN_ARCHIVE = $(LOCAL_THIN_ARCHIVE))
36 $(warning  LOCAL_FILTER_ASM = $(LOCAL_FILTER_ASM))

文件PRINT_APPLICATION_VARIABLE.mk内容如下：

 1 $(warning  APP_PROJECT_PATH = $(APP_PROJECT_PATH))
 2 $(warning  APP_MODULES = $(APP_MODULES))
 3 $(warning  APP_OPTIM = $(APP_OPTIM))
 4 $(warning  APP_CFLAGS = $(APP_CFLAGS))

 7 $(warning  APP_LDFLAGS = $(APP_LDFLAGS))
 8 $(warning  APP_BUILD_SCRIPT = $(APP_BUILD_SCRIPT))
 9 $(warning  APP_ABI = $(APP_ABI))
10 $(warning  APP_PLATFORM = $(APP_PLATFORM))
11 $(warning  APP_STL = $(APP_STL))
12 $(warning  APP_GNUSTL_FORCE_CPP_FEATURES = $(APP_GNUSTL_FORCE_CPP_FEATURES))
13 $(warning  APP_SHORT_COMMANDS = $(APP_SHORT_COMMANDS))
14 $(warning  NDK_TOOLCHAIN_VERSION = $(NDK_TOOLCHAIN_VERSION))
15 $(warning  APP_PIE = $(APP_PIE))
16 $(warning  APP_THIN_ARCHIVE = $(APP_THIN_ARCHIVE))
