Platform Designer problem WSL


Hello, I'm trying to migrate an old project, quartus II/15, to the latest quartus standard edition:

Quartus 21.1.0 Build 842

Patches Installed: 0.01std


Previously the project was run and built in Linux. now I'm trying to get it to work under windows 11

Back during quartusII development I used QSys, I see now that that has been changed for Platform Designer. Whenever I try to Generate HDL I get the following issue:




Error: s0: Error during execution of "{C:/intelfpga/21.1/quartus/../nios2eds/Nios II Command Shell.bat} make all 2>> stderr.txt": child process exited abnormally

I see that I'm not the only one with this issue, and I've tried different solutions. 

1) Tried installing the patch:

2) Tried running while WSL is disabled

3) Tried installing Ubuntu and some packages (saw this 'solution' in another post)


It's a fresh Quartus installation, I can use WSL fine from terminal

Hi elamre,

I have checked and it is like a known issue from other similar cases which happened when worked in Windows environment.

The was a case filed before but still in investigating state. 

It will definately take some time for this issue to be resolved. 

The suggestion I have is to build your project using Linux at the moment. Do feedback to me if there is any concern.

Hi elamre,

I recommend to use the Quartus Linux version instead for now.

The Quartus Windows version will have these errors. I was filling this issue to engineering regarding this matter.

I will close this thread for now.

First, make sure you do all the steps related to the WSL indicated here.

In my case, the problem is due to the WSL default distribution. It should be set on Ubuntu-18.04.
You can list the WSL distributions and check the default using this command:


wsl --list


Also, you can set Ubuntu-18.04 as the default distribution using the following command:


wsl -s Ubuntu-18.04
