最新libwebsockets库的编译与测试方法

1. 环境

在 Ubuntu 16.4.5 TLS 版本中编译和测试通过。

下载最新的源代码需要git，若没有安装git可以使用下面命令进行安装：

sudo apt-get install git -y

另外，还有一些编译的依赖库，相关安装命令如下：

sudo apt-get install cmake -y
sudo apt-get install openssl -y
sudo apt-get install libssl-dev -y

2. 编译及安装

2.1 下载源码

git clone https://github.com/warmcat/libwebsockets.git

2.2 进入源码目录

cd libwebsockets

2.3 创建编译目录并执行CMake

创建编译目录build，并进入，相关命令如下：

mkdir build
cd build

执行cmake，命令如下：

cmake ..

执行结果，如下所示：
