我为userdef.c添加了一些函数otsu_Threshold和onBinarOtzu。 函数库的头文件是pxa_lib.h和我输入功能这样嵌入式Linux。符号查找错误
void otzu_Threshold(unsigned char* orgImg, unsigned char* outImg, int height, int width);
void onBinarOtzu(unsigned char* m_InImg);
在camera.c是在文件夹 '演示'，我输入
'#include < pxa_lib.h >
....
....
onBinarOtzu(vidbuf->ycbcr.y);
生成文件

我制作了二进制文件，并通过minicom，zmodem在机器人中传输。
但是，发生了错误。

什么要高度重视我的工作...
PS。对不起。我不能英语很好...
