 菜鸟实在不懂来求教了……关于NDK编译的问题

在网上找到的资料比较少，一直搞不懂该怎么做
我准备把一个nrf2401的传输程序编译成so文件，驱动已经装好
传输程序原代码如下：
复制代码
  1. #include <stdint.h>
  2. #include <unistd.h>
  3. #include <stdio.h>
  4. #include <stdlib.h>
  5. #include <getopt.h>
  6. #include <fcntl.h>
  7. #include <sys/ioctl.h>
  8. #include <linux/types.h>
  9. #include <linux/spi/spidev.h>
  10. #include "tx01_30_simply.h"
  13. #define ARRAY_SIZE(a) (sizeof(a) / sizeof((a)[0]))

头文件写好以后，写了一个starttx.c文件：
复制代码
  1. #include "tx01_30_simply.h"
  2. #include <jni.h>
  4. jint
  5. Java_com_test_r1_R1_starttx( JNIEnv* env,
  6.                                                   jobject this )
  7. {
  8.     return tx01();
  9. }


android.mk文件是这么写的：
复制代码
  1. LOCAL_PATH := $(call my-dir)
  3. include $(CLEAR_VARS)
  5. LOCAL_MODULE    := tx01
  6. LOCAL_SRC_FILES := tx01_30_simply.c
  7. LOCAL_C_INCLUDES := /opt/FriendlyARM/mini6410/android/linux-2.6.36-android/include
  9. include $(BUILD_SHARED_LIBRARY)
  12. include $(CLEAR_VARS)
  14. LOCAL_MODULE    := starttx
  15. LOCAL_SRC_FILES := starttx.c
  17. LOCAL_STATIC_LIBRARIES := tx01
  19. include $(BUILD_SHARED_LIBRARY)

但是在linux下编译无论如何也无法通过，求助这里的高手们，谢谢！！！
