android.mksdl构建错误

我已经看了一些关于编写android的问题。mk文件和"make: * No rule to make target .c need by .o"**它们都围绕着我认为我没有的拼写错误。

这是一个SDL项目，构建与我的CMake构建脚本很好，但我只是不能得到android。为我工作。

项目子文件夹是我可以创建不同项目和重用我创建的源动态库的地方。

在源代码中，您可以看到我创建了一堆动态库。最后是动态库和一个。h和。c类，它导入了所有这些文件，然后我将这个。h文件导入到我的项目中以使用这些库。

现在来看看我的机器人。mk文件，它还不是很完整，但这是我遇到麻烦的地方。

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := main
SDL_PATH := ../SDL
LOCAL_C_INCLUDES := $(LOCAL_PATH)/$(SDL_PATH)/include/
LOCAL_C_INCLUDES += $(LOCAL_PATH)/src/utils/time_utils/
# Add your application source files here...
LOCAL_SRC_FILES := $(SDL_PATH)/src/main/android/SDL_android_main.c 
                 utils/time_utils.c 
//removing the above line, core_engine.c throws an import error
//adding the above line I get the error listed at the bottom
                 core_engine/core_engine.c 
                 project.c

LOCAL_SHARED_LIBRARIES := SDL2
LOCAL_LDLIBS := -lGLESv1_CM -lGLESv2 -llog
include $(BUILD_SHARED_LIBRARY)
make: *** No rule to make target `/Users/blubee/SDL/android-project/jni/src/time_utils/time_utils.c', needed by `/Users/blubee/SDL/android-project/obj/local/armeabi/objs/main/time_utils/time_utils.o'.  Stop.

每个库都在它自己的文件夹下，在项目源代码树中，像这样

source/components/renderable2d/renderable2d.c /.h
source/core_engine/core_engine.c /.h
source/core_math/mat4_scalar/mat4_scalar.c /.h
source/core_math/vec3_scalar/vec3_scalar.c /.h
source/..
etc...

它可以是一个构建顺序或我在android中定义源文件的顺序。mk文件夹，我不确定。有什么建议吗?我还确保环境变量和android。mk
