How do I install Cygwin for NiosEDS and SoCEDS?


Starting with Intel® Quartus® Prime Standard and Pro Edition software version 19.1 for Windows® and the Intel® SoC FPGA Embedded Development Suite (SoC EDS) version 19.1 for Windows,  the Cygwin component must be installed manually.  Administrative privileges are needed on the PC in order to perform the Cygwin installation.


The procedure for installing Cygwin is:

  1. Go to the official Cygwin website 
  2. Download the 64bit installer (setup-x86_64.exe) 
  3. Open a Windows Command Prompt
  4. Locate the path where Cygwin will be installed. 
    1. For Nios EDS the default path is  C:\intelFPGA_pro\<version>\quartus\bin64\cygwin
    2. For SoC EDS the default path is  C:\intelFPGA_pro\<version>1\embedded\host_tools\cygwin
  5. Run the installer in the Command Prompt with the following parameters (replace <<Path Cygwin Installer>> with the correct path):
  6. setup-x86_64.exe --wait --quiet-mode --root <<<Path Cygwin installer>> --site --packages make,gcc-core,gcc-g++,ncurses,inetutils,openssh,mosh,patch,flex,bison,tar,bzip2,zip,unzip,util-linux,git,subversion,vim,xxd,m4,wget,dos2unix,libintl devel,diffutils,libncurses-devel,iperf,xorg-server,xinit,mingw64-x86_64-gcc-core,mingw64-x86_64-gcc-g++ 
  7. Make sure the command is all on a single line. Copying and pasting from this document may split the command in multiple lines.
  8. Press Enter to issue the command and wait until everything is automatically installed
