    Which version of Quartus are you using? Older version of Quartus are known to have problems with cygwin on newer OSes.

    To fix;

    Download / Install most recent Cygwin w/Perl for both x86 and x86_64.

    I Renamed original folders C:\altera\13.0sp1\quartus\bin\cygwin to \cygwin_original

    C:\altera\13.0sp1\quartus\bin64\cygwin to \cygwin_original

    Created new empty ....\cygwin folders

    Copy paste recent Cygwin into their respective directories C:\altera\13.0sp1\quartus\bin\cygwin (x86) and C:\altera\13.0sp1\quartus\bin64\cygwin (x86_64) directories respectively.

    ok, I went to the cygwin (https://cygwin.com/install.html) page were I downloaded the setup-x86.exe (https://cygwin.com/setup-x86.exe) and setup-x86_64.exe (https://cygwin.com/setup-x86_64.exe) files.

    After runing one of them the installation assistent asked me to select the packages to install.

    What packages should I select? (default, reinstall, uninstall, install)

    I am still having this issue. I have tried the fix posted on the University Programs site. As well as getting cygwin directly from the cygwin dot com site. I tried both the default cygwin install and the complete install. Neither have fixed the problem. Anyone have any other options to try?

    I also deleted the folders in <quartus II install>/bin and /bin64 and re-installed the default cygwin packages and it still fails.

    I'm using quartus 13.0sp1 and am trying to complete the intro tutorial with a DE2 board.

    Hello,

    This is what I did to solve that problem, it worked for me, hope it works for you:

    check this page: http://www.altera.com/education/univ/unv-index.html

    and follow the steps at the end of the page.

    But I warn you, that after I solve that problem, I found another one which is mentioned is this thread:

    http://www.alteraforum.com/forum/showthread.php?t=43109

    So I went back to Quartus 12.1 and everything is working perfect for me now...

    I use Win8 in my desktop and Win8.1 in my laptop, both of them are working fine with Quartus 12.1

    Hope this help you.

    I have resolved my Issue (although I feel there may still be issues)

    When copying all the the cygwin patch files into the altera install directories there is a file <current> with no extention located in <cygwin_patch>\bin64\cygwin\usr\share\groff it is also present in the x86 path <cygwin_patch>\bin64\cygwin\usr\share\groff.

    This file appears to be a symbolic link to the 1.22.2 folder located in the same path. When I open it in notepad++ there is one line that reads !<symlink>1.22.2 NUL

    Having copied every file except for these "current" files into the altera into the install directory I can now successfully compile the tutorial files.

    I am wondering if I should replace the folder within the install folder with the files contained in the 1.22.2 directory. (effectively creating the symbolic link for real) However, I am going to stop here before I do that because it is working with out doing that.
