Clion with wsl2

I will follow the official docs

If you have not installed WSL2, please go to this blog

After installing WSL2 and CLion, open windows PowerShell as administrator and run 

1
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Then restart your computer
open ubuntu and run this command to install c++ tools

1
sudo apt-get install cmake gcc clang gdb build-essential

You will wait a long time.(here I use powershell, I suggest you use ubuntu tu run this command)

Then run this command to open the script

1
wget https://raw.githubusercontent.com/JetBrains/clion-wsl/master/ubuntu_setup_env.sh && bash ubuntu_setup_env.sh

If you are in China, you may can’t download the script by this command

But don’t worry, this is the content of the script

copy this content, and follow me
go to the linux file system

go to this path and create a txt named ubuntu_setup_env.sh, paste the content to this file.

then run this command.
Notice: you should get into the path where you save your bash ubuntu_setup_env.sh file.

1
bash ubuntu_setup_env.sh

It will help us config the ssh

Then run this command, notice the username should be your username

1
ssh username@localhost -p2222

！NOTICE: before you connect to the WSL, you must turn off your fast startup function, or the localhostForward will not work!

Now open your Clion and go to Settings / Preferences | Build, Execution, Deployment | Toolchains and click plus icon to create a new toolchain. Select WSL from the Environment list.

Then click Credentials setting

Fill your information of your WSL, then test connection and OK

If you meet a error, that mean you need to config a file, let me tell you how to solve it.
go to your path like me

create a file named .wslconfig and its content is 

1
2
[wsl2]
localhostForwarding=true

save it and restart your WSL2 on powershell

1
wsl --shutdown

then open WSL2 again

Finally, open Clion you will find it work successfully

Have a good time!
