Linking multiple .c files together in Android.mk

How do i link up or "use" multiple .c files in the Android.mk file?

It currently looks like this 

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := ndk_demo
LOCAL_SRC_FILES := gnutls-3.0.12/lib/debug.c
include $(BUILD_SHARED_LIBRARY)

However, when i try and ndk-build it, it always throws this error

Compile thumb  : ndk_demo <= debug.c

How do i include files like u64.h into the Android.mk so that it won't throw a No such file or directory error? Or am i going about this the wrong way?

If you want to specify several c files, the syntax is like this:

LOCAL_SRC_FILES := \
    my_c_file1.c \
    my_c_file1.c \
    my_c_file2.c \
    my_last_c_file.c

Add the path to your header files into the make file with this directive:

LOCAL_C_INCLUDES := \
    /my_path1_to_h_files/ \
    /my_path2_to_h_files/ \
    /my_pathN_to_h_files/

And if your module uses some shared libraries to link then you can add this:

LOCAL_SHARED_LIBRARIES := \
    lib1 \
    lib2 \
    lib3
