这是找不到共享库造成的。Linux和Windows不一样，不会在可执行文件所在的目录搜索共享库文件。解决的方法已经告诉你了，用export LD_LIBRARY_PATH=/mjpg:$LD_LIBRARY_PATH(你的共享库文件应该是放在/mjpg目录吧)设定共享库的搜索路就可以了。

这个呢 这个怎么都不通

上面问题已解决 但是程序还是出现了错误
[root@FriendlyARM /mjpg]#./mjpg_streamer -o "output_http.so -w ./www" -i "input

那要看mjpg_streamer的源代码才能知道

请问如下的问题有没有遇到过呀，怎么回事呀

/mjpg-streamer # ./start_uvc_yuv.sh
./start_uvc_yuv.sh: line 30: ./mjpg_streamer: not found
