libhv
是一个类似于libevent、libev、libuv
的跨平台网络库,提供了更简单的接口和更丰富的协议。
libhv提供了以下构建方式:
1、通过Makefile:
./configure
make
sudo make install
2、通过cmake:
mkdir build
cd build
cmake ..
cmake --build .
3、通过vcpkg:
vcpkg install libhv
4、通过xmake:
xrepo install libhv
运行脚本./getting_started.sh
:
# 下载编译
git clone https://github.com/ithewei/libhv.git
cd libhv
make
