Notes
In ~/.cache/vscode-cpptools you will find that VSCode store a huge amount of file info, that you can safely clean to regain some disk spaces.
Quick start
Install Code runner extension.
Customize it inside your project to have includes path, eg:
// Edit Executor map
"code-runner.executorMap": {
"cpp": "cd $dir && g++ -std=c++20 -I ~/DEV/cpp -g $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt",For one file program, it’s good enough => It will compile them with debug info, in an executable of same name (use )
To debug this single files, use the C/C++ microsoft extension and invoke directly the gdb config (using current file as target).
// in .vscode/launch.json

}Build task
VSCode’s build in keyboard shortcut to task by making it of type build. The easiest way to set up tasks is to press ctrl+shift+b.
tasks.json
{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
{
"label": "build",
"type": "shell",
"command": "make",
"group": {
"kind": "build",
"isDefault": true,
},
"problemMatcher": "$gcc"
}
]
}Debug Task / LLDB / GDB
Ctrl+F5 => Run / F5 => Debug
launch.json
"preLaunchTask": "build"
