I've looked around at some questions about writing android.mk files and the "make: * No rule to make target .c needed by .o"** they all center around typos which I don't think that I have.
This is an SDL project that builds fine with my CMake build scripts but I just can't get android.mk to work for me.
Here's the project setup in cmake
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
PROJECT(blp)
#set(CMAKE_MACOSX_RPATH 1)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)

the project subfolder is where I can create different projects and reuse the source dynamic libs that I create.
inside the source, you can see I have a bunch of dynamic libs that are created. At the end there's the dynamic libs and one .h and .c class that imports all of them, then I import that one .h file inside my project to use the libs.
Now onto my android.mk file, it's not very complete yet but this is where I am running into trouble.
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.
each lib is under it's own folder int he project source tree like this
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...
It could be a build oder or the order in which I am defining the sources files in the android.mk folder, I am not sure. Any suggestions? I also made sure that there's no typos or extra spaces in my environment variables or the source file for the android.mk
