AWS KVS(Kinesis Video Streams)之WebRTC移植编译（四）_kvs wertc和libjingle

在前面几篇文章中我们已经进行了依赖库的编译，因此，现在需要最终我们需要使用的库libkvsWebrtcClient.a 或者libkvsWebrtcClient.so

如下操作是编译君正（T31X）平台的libkvsWebrtcClient.a 或者libkvsWebrtcClient.so

1、下载源码（amazon-kinesis-video-streams-webrtc-sdk-c）

我们新建几个目录：

Library/T31X 用于存放依赖的库和头文件；

Build/T31X 用于存放编译脚本；

Bin/T31X 用于存放生成的目标文件；

2、编译脚本

这个时候我们只差最后一步了，编译两个最关键的库，详见下一页（点击）
