ubuntu 下使用vscode 进行cmake 编译c++ 工程

步骤一: c++ 工程含有正确的CMakeLists.txt , 使用vscode 打开工程

在.vscode要建立三个json文件才能对Cmake工程进行编译和调试,分别是c_cpp_properties.json,launch.json和tasks.json

步骤2: Ctrl+Shift+P,输入C/C++,选择C/C++: Edit Configurations(JSON) ,创建并修改c_cpp_properties.json文件,修改为如下:

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
            ],
            "defines": [],
            "compilerPath": "/usr/bin/g++",
            "cStandard": "c11",
            "cppStandard": "c++98",
            "intelliSenseMode": "linux-gcc-x64"
            "configurationProvider": "ms-vscode.cmake-tools"
        }
    ],
    "version": 4
}

步骤3: choose Run > Add Configuration... and then choose C++ (GDB/LLDB),配置修改launch.json文件,配置如下:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            // Resolved by CMake Tools:
            "program": "${workspaceFolder}/build/Hello",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

步骤4:  choose Terminal > Configure Default Build Task. A dropdown appears showing various predefined build tasks for C++ compilers. Choose C/C++: g++ build active file. 修改编辑

tasks.json是编译任务的文件(或者用默认的tasks)

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "make build",//编译的项目名,build
            "type": "shell",
            "command": "cd ./build ;cmake .. ;make",//编译命令
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        {
            "label": "clean",
            "type": "shell",
            "command": "make clean",
            

        }
    ]
}

步骤5: ctrl+shift+B运行代码,成功

步骤6:F5 debug 调试
