---WebCam网络摄像头6 编译WebCam
直接使用天嵌提供的交叉编译器编译WebCam而生成的input_uvc.so output_http.souvc_stream放在micro2440下面可以直接使用--两个开发板几乎没什么不同。。。
而如果要用友善提供的交叉编译器，去编译天嵌的WebCam会发生错误。。。因为编译的时候需要SDL库，而友善的4.3.2没有加入此库。下面是源码树。

以下所有编译使用友善配的4.3.2编译器
参考天嵌摄像头移植手册
1.移植SDL库：
http://www.libsdl.org/release/SDL-1.2.13.tar.gz 下载之后考到/opt/FriendlyArm/mini2440/目录下
编译uvc-streamer
将bin-song.tgz弄到micro2440上，执行：
