Why do I see errors like wsl dos2unix create-this-app;./create-this-app --no-make or make: command not found when running Nios® II Software Build Tools for Eclipse on Windows?

These problems might be seen in the Quartus® Prime Standard Edition Software version 21.1 when using the Nios® II Software Build Tools for Eclipse in Windows operating system (OS) to build the Nios II processor software.

This is due to incorrect WSLENV variables set due to a problem in the Eclipse executables.

The following errors might be seen when building the Nios II processor software using Windows Subsystem for Linux (WSL):

1. wsl dos2unix create-this-app;./create-this-app --no-make
   • This error may be prompted when launching the Nios® II Software Build Tools for Eclipse from Windows menu.
2. make: command not found 
   • This error may be prompted when launching the Nios® II Software Build Tools for Eclipse from the Nios® II Command Shell.
