Cygwin

 
 
Cygwin is a Linux-like environment for Windows. It consists of two parts:
  • A DLL (cygwin1.dll) which acts as a Linux emulation layer providing substantial Linux API functionality.
  • A collection of the popular GNU development tools.
Cygwin runs on all modern 32 bit versions of Windows, except Windows CE. This includes Windows 95/98/ME/NT/2000/XP/Vista. Cygwin is distributed at no charge for commercial or non-commercial use. For more information read the Cygwin licensing terms.

Information
If you know the utility name for example "diff" and "patch" but you do not know in which package(s) these utilities are available, follow this guide.

Operating system used
Windows XP Home Edition Version 5.1 SP 2

Software prerequisites
Cygwin


Procedure
  1. Go to http://sources.redhat.com/cygwin/packages/.

  2. Enter the utility name in the "Search Package List" text box.
    Be as specific as possible.

    For example:
    Type: /diff.exe and press the Go button.
    Type: /patch.exe and press the Go button.

    Note: If you just entered diff.exe you will find more solutions.

  3. diff.exe can be found in package "diffutils".
    patch.exe can be found in package "patch".

  4. Start up the setup.exe utility, see guide "Installing Cygwin" and press the View button untill the view style shows "Full".

    Cygwin show packages

  5. By clicking on the toggle Cygwin toggle you can install both packages.

    Note 1: If you do not see these packages then it is NOT downloaded in your "Local Package Directory". Please follow the guide "Installing Cygwin" if you do not understand this concept.

    Note 2:
    In this example binutils is already installed. Next to the toggle the word "Keep" is shown which means this package is already installed.

    If the toggle shows "Skip" the package is not installed. To install the package press the toggle until a version number is diplayed.

  6. If both packages are installed, verify this:

    • Open a dos window.

    • Type: diff --help
      The diff help is displayed.

    • Type: patch --help
      The patch help is displayed.
