直接使用天嵌提供的交叉編譯器編譯WebCam而生成的input_uvc.so output_http.souvc_stream放在micro2440下面可以直接使用--兩個(gè)開發(fā)板幾乎沒什么不同。。。
而如果要用友善提供的交叉編譯器，去編譯天嵌的WebCam會發(fā)生錯(cuò)誤。。。因?yàn)榫幾g的時(shí)候需要SDL庫，而友善的4.3.2沒有加入此庫。下面是源碼樹。

編譯uvc-streamer
[root@localhost uvc-streamer]# pwd /opt/FriendlyArm/mini2440/WebCam/mjpg-streamer/uvc-streamer [root@localhost uvc-streamer]# make 編譯mjpg-streamer，并打包所需文件為bin-song.tgz
[root@localhost mjpg-streamer]# pwd /opt/FriendlyArm/mini2440/WebCam/mjpg-streamer/mjpg-streamer [root@localhost mjpg-streamer]# make [root@localhost mjpg-streamer]# tar cvzf bin-song.tgz mjpg_streamer input_uvc.so input_cmoscamera.so output_http.so www/ ../uvc-streamer/uvc_stream 3.
將bin-song.tgz弄到micro2440上，執(zhí)行：
