Required $SOPC_KIT_NIOS2 Environmental Variable is not set - Required $SOPC_KIT_NIOS2 Environmental Variable is not set Hi, I'm trying to get the Nios II Eclipse toolchain to work on a Windows 10 machine. But the New Project wizard ( File -> New -> Nios II Application and BSP from Template ) does fail with the error: Executing: wsl ./create-this-app --no-make (C:\some\directory\projectname\qsys\software\test_software) Required $SOPC_KIT_NIOS2 Environmental Variable is not set! I've set the SOPC_KIT_NIOS2 variable to " C:\intelFPGA_pro\19.2\nios2eds " both on Windows and the WSL Linux (Ubuntu 18.04 LTS) and also in the Eclipse settings ( C/C++ -> Build -> Environment ). But the error still occurs. Did I miss something? Or is there a way to set the Nios II toolchain to use Cygwin instead of wsl? Thanks Edit: I could narrow the problem to the wsl command: bash -c "echo $SOPC_KIT_NIOS2" outputs the environment variable correctly, but wsl echo $SOPC_KIT_NIOS2 can't find it. Sadly the generated scripts use the wsl command... How can this be resolved? Replies: Re: Required $SOPC_KIT_NIOS2 Environmental Variable is not set Great :). I have no idea how you worked this out but it worked for me Replies: Re: Required $SOPC_KIT_NIOS2 Environmental Variable is not set Found the answer: Created a new environment variable in Windows: Name: WSLENV Value: SOPC_KIT_NIOS2/p After restarting Eclipse and Quartus it worked.
