Windows10で、VSCodeを使ったC言語の開発環境を作りました。MinGWを使わず、WSL2のubuntu内にあるコンパイラを使う環境を今回作りました。

手順

 wsl --set-default-version 2

sudo apt update

sudo apt install build-essential

1. Ctl+Shift + B でビルド開始

> Executing task: C/C++: gcc build active file <

Starting build...
Build finished successfully.

Terminal will be reused by tasks, press any key to close it.

1. Ctl + Shift + @ でターミナルを開き、ビルドデータの確認をする
   • mainという実行ファイルが生成されている
2. ビルドデータを実行する
   • ./main
