最近在学习libevent，记录一下安装过程，方便日后查看。

首先，安装openssl

1.下载openssl源码: /source/index.html (openssl.org)

wget https://www.openssl.org/source/openssl-1.1.1l.tar.gz

2.解压

tar -zxvf openssl-1.1.1l.tar.gz
cd openssl-1.1.1l/

3.编译安装

./config
make -j16
sudo make install

然后，安装libevent

1.到官网找到最新版本并下载 ：libevent

wget https://github.com/libevent/libevent/releases/download/release-2.1.12-stable/libevent-2.1.12-stable.tar.gz

2.解压

tar -zxvf libevent-2.1.12-stable.tar.gz
cd libevent-2.1.12-stable/

3.编译安装

mkdir build
cd build
cmake ..
make -j16
sudo make install

至此安装完成

CmakeList中加入：

target_link_libraries(TestInstall event)

编译过程中出现错误：找不到共享库文件

这是因为默认安装到了/usr/local/bin

需要手动拷贝到/usr/bin

sudo cp /usr/local/lib/libevent-2.1.so.7 /usr/lib

Over!
