基于Clion IDE的CPP项目构建与运行
工具基本信息
1.CLion
CLion:
A cross-platform IDE for C and C++
CLion takes a lot of the toil out of C++, allowing me to concentrate on the interesting part: problem solving.
- 下载地址
1
https://www.jetbrains.com/clion/download/#section=windows
2.MingW
A complete runtime environment for GCC & LLVMfor 32 and 64 bit Windows
- 下载地址（x64、posix、.seh版本）
1
https://sourceforge.net/projects/mingw-w64/files/mingw-w64/mingw-w64-release/
- 如图
3.CMake
CMake允许开发者编写一种平台无关的 CMakeList.txt 文件来定制整个编译流程，然后再根据目标用户的平台进一步生成所需的本地化 Makefile 和工程文件
- 基本指令
1 | cmake_minimum_required：指定运行此配置文件所需的 CMake 的最低版本； |
- 举例
1 | # CMake 最低版本号要求 |
工具安装构建
CLion
1.新建cpp项目
如图
2.编写测试代码
- 1.src/test.cpp
定义socket套机字，构建socket服务端；实现登录、登出、数据转发等功能
