As an embedded engineer, I often need to practice Linux programming on my Windows laptop. I believe that installing a distro directly into the system is superfluous and somewhat complex.
I have since discovered WSL, which is more practical. Thus, I make a few notes about how to configure the system to run and build code.
This is for some one who knows how to do it but struggles to make it work
1. Use virtual machine
Firstly, I remind everyone about the old-school method with VM
You need Virtual machine with an Ubuntu distro. I choose Kubuntu because I think it is less prone to error than Ubuntu ( just my personal experience).
Install ssh to Ubuntu then enable it
The most important part is setting up Network in VM
The guess IP is the IP in Ubuntu you get from the ifconfig command.
You can test the connection in command window
Now open VSCode or Visual studio, install SSH extension and create new one, use the same command above and you are good to write code.
2. Use WSL
WSL stands for Windows Subsystem for Linux. In short, it works like below
This is the best tutorial on how to install WSL and connect it with VSCode. Just follow it.
Now you can access a Linux system like using VM, we come to the most important part, compile and run/debug source code.
You need to create a Hello world cpp file to test.
We need tasks.json file to compile the code in Linux and a launch.json file to debug.
tasks.json
{
"version": "2.0.0",
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: g++ build active file",
"command": "/usr/bin/g++",
"args": [
"-fdiagnostics-color=always",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": "build",
"detail": "compiler: /usr/bin/g++"
}
]
}
Install gdb to Linux using command
sudo apt install gdb
Now check where gdb is
Config launch.json file and update miDebuggerPath with the path you get
{

"version": "0.2.0",
"configurations": [
{
"name": "debug",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}/${fileBasenameNoExtension}",
"MIMode": "gdb",
"cwd": "${fileDirname}",
"miDebuggerPath": "/usr/bin/gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
},
{
"description": "Set Disassembly Flavor to Intel",
"text": "-gdb-set disassembly-flavor intel",
"ignoreFailures": true
}
],
"preLaunchTask": "C/C++: g++ build active file"
}
]
}
To compile code, use Ctrl Shift B
