Installing Cygwin

  1. Download the latest version of Cygwin and save it to a temporary folder.

    See http://cygwin.com/install.html to download.

  2. Run setup.exe. Ensure that these are included:

    • All packages under the Base category

    • sharutils under Archive category

    • bc under Math category

    • dos2unix under Text category

    • util-linux under Utils category

    <CygwinRoot> represents Cygwin's installation directory
  3. After the installation, remove or rename perl.exe that came with Cygwin.

    <CygwinRoot>\bin\perl.exe

  4. Remove or rename uname.exe that came with Cygwin.

    <CygwinRoot>\bin\uname.exe

  5. Add these system environment variables. Ensure that these environment variables are available to all running processes.

    • CYGWIN=nodosfilewarning noenvcache

    • CYGROOT=<CygwinRoot>

      Example

      CYGROOT=E:\cygwin

  6. Specify the <CygwinRoot>/etc/fstab file and change the first line to:

    none /cygdrive cygdrive binary,posix=0,user,noacl 0 0

    Then, add this information at the end of the line:

    <LSFRoot> <LSFRoot without the drive letter> ntfs noacl,posix=0,nouser

    Example

    D:/lsf1001 /lsf1001 ntfs noacl,posix=0,nouser

    Note: When you create a mount point on fstab and the directory folder is two or more levels from the root folder, the mount point is not going to take effect unless an equivalent directory structure is created in <CygwinRoot>.

    • The syntax of fstab entry structure:

      <native Windows path> /<mount point> <filesystem type> <mount options>

      Example: 

      C:/level1_folder/level2_folder /level1_folder/level2_folder ntfs noacl,posix=0,nouser

    • Create equivalent directory under <CygwinRoot>:

      Example:

      <CygwinRoot>/level1_folder/level2_folder
