Initial mount-points can be configured in /etc/fstab, which has a format very similar to Unix systems, except that Windows paths appear in place of devices. A Cygwin-specific version of the Unix mount command allows mounting Windows paths as "filesystems" in the Unix file space.A complete installation will take in excess of 90 GB of hard disk space, but usable configurations may require as little as 1 or 2 GB.Įfforts to reconcile concepts that differ between Unix and Windows systems include:

Setup can install, update, and remove programs and their source code packages. As mentioned, there are two versions of this setup program, one for 32-bit versions of the Cygwin DLL, and corresponding applications, and one for 64-bit versions. Cygwin permits installing inetd, syslogd, sshd, Apache, and other daemons as standard Windows services, allowing Microsoft Windows systems to emulate Unix and Linux servers.Ĭygwin programs are installed by running Cygwin's "setup" program, which downloads the necessary program and feature package files from repositories on the Internet.
Programmers have ported many Unix, GNU, BSD and Linux programs and packages to Cygwin, including the X Window System, K Desktop Environment 3, GNOME, Apache, and TeX.

Cygwin consists of a library that implements the POSIX system call API in terms of Windows system calls, a GNU development toolchain (including GCC and GDB) to allow software development, and running of a large number of application programs equivalent to those on Unix systems.

The Cygwin environment is provided in two versions the full 64-bit version and a stripped down 32-bit version that is slowly being phased out. Rather than rewrite the tools to use the Win32 runtime environment, Cygwin implemented a POSIX compatible environment in form of a dynamic-link library (DLL). It was originally developed by Cygnus Solutions, which was later acquired by Red Hat (now part of IBM), to port the Linux toolchain to Win32, including the GNU Compiler Suite.

Ĭygwin is free and open-source software, released under the GNU Lesser General Public License version 3. Thus it is possible to launch Windows applications from the Cygwin environment, as well as to use Cygwin tools and applications within the Windows operating context.Ĭygwin consists of two parts: a dynamic-link library (DLL) as an API compatibility layer in the form of a C standard library providing a substantial part of the POSIX API functionality, and an extensive collection of software tools and applications that provide a Unix-like look and feel. Ĭygwin provides native integration of Windows-based applications. The terminal emulator Mintty is the default command-line interface provided to interact with the environment. Additionally, many applications may be installed from a packaging system. Cygwin installs with hundreds of command-line tools and other programs commonly found on a Unix-like system. The Cygwin installation directory has a directory layout that is similar to the root file system of Unix-like systems, with familiar directories, such as /bin, /home, /etc, /usr, and /var. Under Cygwin, source code designed for Unix-like operating systems may be compiled with minimal modification and executed.
