android - 如何在 Android.mk 文件中指定要复制的文件

Question

是否有复制文件的宏或命令？我想要将第 3 方库 (libThirdParty.so) 复制到输出目录 (lib)。这是我的 Android.mk 文件的内容

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := ndkFoo
LOCAL_SRC_FILES := ndkFoo.c

LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog

include $(BUILD_SHARED_LIBRARY)

我为生成的一个 .cpp 文件添加了构建步骤；你可以做类似的事情。

请注意，我被告知我正在做的事情不受 Google 支持，因此使用风险自负。不过，一年多来我一直在使用类似下面的代码。这是它的大概样子:

LOCAL_PATH:= $(call my-dir)
# this was important for some cases; can't remember if it's important here, but I don't want to steer you wrong if it isn't
REAL_LOCAL_PATH:=$(LOCAL_PATH) 

include $(CLEAR_VARS)

LOCAL_MODULE    := ndkFoo
# again, I'm being paranoid here
REAL_LOCAL_MODULE    := $(LOCAL_MODULE)

LOCAL_SRC_FILES := ndkFoo.c

$(REAL_LOCAL_PATH)/obj/local/armeabi/$(REAL_LOCAL_MODULE).so : $(REAL_LOCAL_PATH)/libs/armeabi/libThirdParty.so

$(REAL_LOCAL_PATH)/libs/armeabi/libThirdParty.so : $(PATH_TO_LIB_THIRD_PARTY)/libThirdParty.so
    cp $(PATH_TO_LIB_THIRD_PARTY)/libThirdParty.so $(REAL_LOCAL_PATH)/libs/armeabi/libThirdParty.so

LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog
include $(BUILD_SHARED_LIBRARY)

请注意，您需要定义 PATH_TO_LIB_THIRD_PARTY。

另请注意，复制粘贴可能有效也可能无效。众所周知，Makefile 对缩进很挑剔。我会确保“cp”行有一个真正的制表符缩进，并且没有其他缩进。如果“cp”不起作用，则 make 可能正在委托(delegate)给 CMD，您可以尝试“复制”。

祝你好运。
