mjpg-streamer-r63 交叉编译成功 RT5350

 

请尊重别人的劳动成果 转载请务必注明出处

今天静下心来，看看上次为啥arm编译的mjpeg streamer是ok的，而编译mips却提示V4L相关的错误信息，今天仔细看了下是由于mjepg streamer比较新，V4L的接口发生了变化，而该死的ralink还在使用2.6.21的内核以及3.4.2的编译器。而arm则正好符合mjepg streamer的接口。所以一口气就编译通过了。

为此俺们遇到啥就解决啥，逢山开路，遇水搭桥。见佛杀佛，见鬼杀鬼，没有的就补上。一路修改终于编译出来。主要添加的是V4L的接口结构体以及宏等

不过编译出来还有些警告，先不理会。看看能否run的起来！
