VSCode + CMake编译C/C++教程

路线图

[x] 所需MSYS包安装
[x] VSCode插件和环境配置
[x] GCC平台编译
[ ] MSVC CL平台编译

目的

在Windows平台中继续使用VS Code编写调试C/C++程序
在Windows平台中兼顾gcc的项目编译，减少跨平台错误
避免使用Visual Studio的相应键位，使用VS Code的高效编辑

准备

MSYS2(推荐) / MinGW
VSCode
VSCode 插件 (C/C++, Cmake, Cmake-tools)

路径与环境变量设置

MSYS_DIR=C:\msys64
MINGW64_DIR=C:\msys64\mingw64
加入Path: %MSYS_DIR%\usr\bin, %MINGW64_DIR%\bin

MSYS安装配置

安装MSYS2

修改MSYS的Server配置，分别在对应文件开头加入如下语句

# in mirrorlist.msys
Server = http://mirrors.ustc.edu.cn/msys2/msys/$arch 
# in mirrorlist.mingw64
Server = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64
# in mirrorlist.mingw32
Server = http://mirrors.ustc.edu.cn/msys2/mingw/i686

从MSYS库安装msys/make
安装MinGW库安装gcc、gdb、cmake、make和opencv、boost(可选)等相关组件库

VSCode配置

建立项目文件夹

Ctrl+Shift+P -> C/Cpp: Edit Configuration..., 输入如下配置: (若是gcc位置不同，需要自行修改compilerPath和includePath)

{
     "configurations": [
         {
             "name": "clang",
             "includePath": [
                 "${workspaceFolder}/**",
                 "C:/msys64/mingw64/include"
             ],
             "defines": [
                 "_DEBUG",
                 "UNICODE",
                 "_UNICODE"
             ],
             "compilerPath": "c:/msys64/mingw64/bin/gcc.exe", 
             "cStandard": "c11",
             "cppStandard": "c++17",
             "intelliSenseMode": "clang-x64"
         }
     ],
     "version": 4
 }

编写C/C++文件

配置当前Workspace中的C/C++ IntelliSense设置：

{
     "cmake.configureOnOpen": true,
     "cmake.generator": "MSYS Makefiles",
     "C_Cpp.default.configurationProvider": "vector-of-bool.cmake-tools"
 }

在项目根目录下建立CMakeLists.txt,配置项目的主要编译内容(参见文件夹中的三个例子)
在对应的自定义包目录下建立CMakeLists.txt,将对应的子目录声明加入对应的模块
在根目录CMakeLists.txt使用Ctrl+Shift+P -> CMake: Configure来配置项目环境变量
Ctrl+Shift+P -> CMake: Build
到对应的build目录下找到对应的可执行文件

配置调试launch.json,参考模板如下:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/cmtst.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "C:/msys64/mingw64/bin/gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}
