VSCode MAC CPP运行环境配置

使用vscode运行cpp确实挺麻烦的，需要配置几个文件，简单来说：

• c_cpp_properties.json 用来配置编译器和编译选项
• launch.json 用来配置运行时选项
• tasks.json 用来配置debug选项

.vscode/c_cpp_properties.json

{"configurations": [{"name": "Mac","includePath": ["${workspaceFolder}/**"],"defines": [],"macFrameworkPath": ["/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks"],"compilerPath": "/usr/bin/clang++","cStandard": "c17","cppStandard": "c++17","intelliSenseMode": "macos-clang-x64"}],"version": 4
}

.vscode/launch.json

{"version": "0.2.0","configurations": [{"type": "lldb","request": "launch","name": "mydb","program": "${fileDirname}/${fileBasenameNoExtension}","args": [],"cwd": "${workspaceFolder}","preLaunchTask": "Build with Clang"}]}

注意type改成lldb，program选项填生成的可执行文件，cwd选项填当前工作路径，preLaunchTask选项填写tasks.json的label。

.vscode/tasks.json

{"version": "2.0.0","tasks": [{"label": "Build with Clang","type": "shell","command": "clang++","args": ["-std=c++17","-stdlib=libc++","-g","${file}","-o","${fileDirname}/${fileBasenameNoExtension}","--debug"],"group": "build"},]
}

注意label选项，type应该无所谓，args要填对，-g是要编译的文件，-o是编译输出文件名。
