Project creation failed with latest Quartus Prime Standard 23.1

Which Operating System (OS) are you using?

If Window OS, could you check if the WSL (Windows Subsystem for Linux) feature is turn ON and is using WSL version 1?

Nios II is not supported in WSL2, as mentioned here.

Therefore, you need to install WSL 1 and use this version.

To do that use the following steps.

• Open the start menu and type Turn Windows features on or off

• In the window that appears, click on Windows Subsystem for Linux and, when prompted, restart your PC.

• Open a command prompt as administrator and type "wsl --list --verbose". You should get something like the following:

C:\Users\xxx> wsl --list --verbose

If the version is 2, then continue to the next step. Otherwise, you can skip the next step.

• If the version is 2, type wsl --set-version Ubuntu 1 where “Ubuntu” is the name of the distribution from the previous step. You should get something like this:

C:\Users\xxx> wsl --set-version Ubuntu 1

Conversion in progress, this may take a few minutes.

The operation completed successfully.

Now, if you type "wsl --list --verbose" again, you should have “1” under the “VERSION” column.

Next step:

• Type wsl -u root to enter the Ubuntu terminal and issue the following commands:

o apt update

o apt install wsl dos2unix make build-essential

Wait until the installation finishes.

After that, open Quartus and try generating the IP again.

In the case of Linux, you may need to install make and build-essential to get this to work.
