How to install the Windows* Subsystem for Linux* (WSL) on Windows* OS? - How to install the Windows* Subsystem for Linux* (WSL) on Windows* OS? Description Starting with the Nios® II EDS in the Intel® Quartus® Prime Pro Edition Software version 19.2 and Intel® Quartus® Prime Standard Edition Software version 19.1, the Cygwin component in the Windows* version of Nios II EDS has been removed and replaced with WSL. Resolution The procedure for installing WSL is: Follow standard instructions from Microsoft® to install Ubuntu* 18.04 LTS for WSL . Refer to https://docs.microsoft.com/en-us/windows/wsl/install-win10 . The recommended OS would be Windows* 10 build version 16215.0 or higher. NIOS II currently does not support WSL 2. Remember: In Windows Features, ensure to turn on the Windows Subsystem for Linux option. After the installation is successful , launch the Ubuntu 18.04 app . Install the additional distro packages that are required for Nios® II EDS using the following commands: a. sudo apt update b. sudo apt install wsl c. sudo apt install dos2unix d. sudo apt install make e. sudo apt install build-essential Note: Ensure that all package dependencies, repositories lists, and Internet connections for WSL are set correctly. For Nios II Command Shell, launch the Windows executables of the command line tool s by adding ".exe" (for example eclipse-nios2.exe or jtagconfig.exe).
