libevent交叉编译

libevent交叉编译

正常编译

1. 解压
   tar zxvf libevent-2.0.10-stable.tar.gz
2. 进入目录
   cd libevent-2.0.10-stable
3. 设置安装路径
   ./configure --prefix=/usr
4. 编译
   make
5. 安装
   make install

坑：

1. 默认是安装到/usr/local下的，程序执行时找不到包，可在CmakeLists.txt中修改三方包的路径

交叉编译

1. 解压
   tar zxvf libevent-2.0.10-stable.tar.gz
2. 进入目录
   cd libevent-2.0.10-stable
3. 设置安装路径， arm环境命令，根据机器类型替换相应参数
   ./configure --prefix=/home/arm/libevent --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++
4. 编译
   make
5. 安装
   make install
6. arm移植
   将/home/arm/libevent平移到arm环境即可
