vscode linux c++ 配置

简介

最官方的配置方案 https://code.visualstudio.com/docs/cpp/config-linux

有三个文件会生成

tasks.json （编译器构建设置）
launch.json （调试器设置）
c_cpp_properties.json （编译器路径和IntelliSense设置）

三个文件的配置命令

tasks.json

Terminal > Configure Default Build Task
选择 C/C++: g++ build active file

lauch.json

Run > Add Configuration... and then choose C++ (GDB/LLDB).
选择 Choose g++ build and debug active file.

c_cpp_properties.json

ctrl + shift + p 打开命令行 输入 c/c++
选择带有 ui 的那个
C/C++: Edit Configurations (UI)

复用配置文件

VS Code现在已配置为在Linux上使用gcc。该配置适用于当前工作空间。要重用配置，只需将JSON文件复制到.vscode新项目文件夹（工作区）中的文件夹中，然后根据需要更改源文件和可执行文件的名称。
