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.

  10. The chooser window is now displayed.

    Packages are grouped into categories and one package may belong to multiple categories. Each package can be found under any of those categories in the heirarchial chooser view.

    By default setup.exe will install only the packages in the Base category and their dependencies, resulting in a minimal Cygwin installation.

    Setup.exe automatically selects dependencies. Be careful not to unselect any required packages. In particular, everything in the Base category is required.
