1 安裝C++與CMake插件

C++插件

CMake插件

2 配置CMakeLists.txt

編寫測試程序

#include<iostream>int main(int argc, char const *argv[]) {int a = 1, b = 2;int c = a + b;int d = a - b;std::cout << "Done!" << std::endl;return 0;
}

編寫構建腳本CMakeLists.txt

cmake_minimum_required(VERSION 3.12)
project(DebugProject)add_executable(main.out main.cpp)

3 使用CMake編譯調試

3.1 編譯

Command + Shift + P 輸入CMake 輸入CMake: Configure 指定要構建的文件

進入CMake Tools插件，可以看到CMake中的各種命令

在PROJECT OUTLINE中點擊進行debug構建

3.2 調試

在編輯器中添加斷點

進入CMake Tools插件，點擊Debug按鈕，開始調試

可以看到已經運行到斷點處，因此可以繼續進行調試

4 自定義構建調試

進入CMakeList.txt 所在的目錄，編譯并構建

cd CMakeLists.txt所在目錄
cmake -B build -DCMAKE_BUILD_TYPE=Debug
cmake --build build

進入Debug并配置launch.json

選擇調試器

生成調試配置

選擇lldb(launch)

}

可以自定義多個調試器，分別進行調試即可
【注意】C++程序修改后需要重新進行編譯cmake --build build

{"version": "0.2.0","configurations": [{"name": "CMakeTestDebug2","type": "cppdbg","request": "launch","program": "${workspaceFolder}/CPPNote/CH00_CPP/01_Debug/02/build/main.out","args": [],"stopAtEntry": false,"cwd": "${fileDirname}","environment": [],"externalConsole": false,"MIMode": "lldb"},{"name": "CMakeTestDebug1","type": "cppdbg","request": "launch","program": "${workspaceFolder}/CPPNote/CH00_CPP/01_Debug/01/build/main.out","args": [],"stopAtEntry": false,"cwd": "${fileDirname}","environment": [],"externalConsole": false,"MIMode": "lldb"}]
}
