Found patches for Quartus Pro and Standard editions at:
None listed for the Lite edition. Tried the standard edition patch and it fixed one of two error messages but still have the Argument error "nios2-elf-g++.exe: error: missing argument to '-msys-lib='".
Any fixes for the Quartus Lite edition?
I was talking with the team and you can use the patch for standard edition on the lite edition. But you need to use 20.1 or 19.1.
