Quartus 18.1 Lite Platform Designer DDR3 Controller can't build when WSL is enabled

@EricMunYew_C_Intel : I am not sure what you mean that the question has been addressed.

Nobody gave a solution for OPs post.

So anyone reading this thread, here is my workaround for the same issue that I have in quartus web 15.0

Here are some files that needed to be modified/created:

bash-cygwin.exe is a copy of bash.exe

nios2-bsp and nios2-newlib-gen have a modifed shebang which looks like this:

#!/bin/bash-cygwin

The fix is basically making sure, that the wsl bash is not called anymore.

Here is a look from process monitor, about the root cause: Normally the bash.exe from cygwin is called, but the shebang in the file somehow ends up calling the wsl bash.exe

Cheers for all the folks out there who need to use an older quartus but also want to have wsl installed.
