VSCode configure C++

Every time you change computers to write C++, you have to find the configuration, which is very cumbersome. This time I wrote a blog and recorded the relevant configuration.

Install the compiler

Open the website below http://www.msys2.org/, download the 64-bit version MYSYS2, and follow the steps on the home page to install the software. After the completion, enter the /etc/pacman.ddirectory and modify the following three files respectively.

1. The content of the mirrorlist.mingw32 file is:
   Server = http://mirrors.ustc.edu.cn/msys2/mingw/i686/

2. The content of the mirrorlist.mingw64 file is:
   Server = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64/

3. The contents of the mirrorlist.msys file are:
   Server = http://mirrors.ustc.edu.cn/msys2/msys/$arch/

Then allow the following command to update the system.

cd ~
pacman -Syu

Install the c++ tools.

pacman -S mingw-w64-x86_64-toolchain

A prompt appears, select 3, 9, and 13 respectively. Wait for the installation to complete.

After completion, e:\Softwares\msys64\mingw64\bin\add to the system environment. Note: The installation e:\Softwaresdirectory is adjusted according to the actual situation.

Install VSCode

This time, we chose VsCode as the tool, which is convenient and practical. Although the C++ plug-in is a bit weak, the one developed by Microsoft will not be too bad. After the installation is complete, select c/c++Plugins . See below.

Open the software, then in the Filemenu, click Add Folder to Workspace..., select a directory as the folder for writing c++ code later, here we assume that the selected folder is cpp. Create a new directory under cpp , and .vscodethen create three files .vscodeunder the , directory, respectively . See below.task.jsonc_cpp_properties.jsonlaunch.json

launch.jsonFor code debugging, it doesn't work yet.

run the code

After completing the above work, in the cpp directory, write a test.cpp file, and then press Ctrl+Shift+B, the test.exe file will be generated.
