This guide was tested under Windows 10. It should be work with other supported Windows Versions too.
Jan 02, 2019 Note: Cygwin uses a magic cookie to identify symlinks. To have Cygwin create symlinks that can be followed from WSL, create an environment variable CYGWIN and set the value to winsymlinks:native. Cygwin tries to bring a POSIX-compatible environment to Windows so that most software that runs on unices will build and run on Cygwin without any significant modifications. Cygwin provides a large collection of packages containing such software, and libraries for their development. This package was approved as a trusted package on 30 Mar 2021. Cygwin is a collection of tools which provide a Linux look and feel environment for Windows. Cygwin is also a DLL (cygwin1.dll) which acts as a Linux API layer providing substantial Linux API functionality.
Install Cygwin (without admin rights)¶
- I am trying to run linux driver on linux environment. Following instruction to run winkvm. Stuck on point run make command using cygwin environment. Like Building original KVM drivers using.
- Cygwin related projects. Cygwin has 8 repositories available. Follow their code on GitHub.
This documentation is based on Oliver Doepner's IT blog. Thank you for your work Oliver.
- Download setup-x86_64.exe.
- Open command line window (WIN+R and type
cmd
). - Go to the download directory, e. g.:
- Run setup-x86_64.exe with the
--no-admin
option: - During installation select the
wget
package. - After installation open a Cygwin Terminal via Windows desktop shortcut.
- If you are behind an internet proxy (for example on a company environment) create
/etc/profile.d/proxy.sh
for internet access: - Now you need a file called
/usr/local/bin/cyg-get
. Downlaod it viaAlternatively, you can also create the file yourself. - Make the script executable:
- On the Windows desktop create a copy of the Cygwin terminal shortcut, rename it Cygwin Setup.
- Edit the shortcut target, replace:with
- Now test it and execute the desktop shortcut or run cyg-get from the Cygwin commandprompt.

Cygwin Package Management¶
With the created script
/usr/local/bin/cyg-get
you can do package management on command line like in a linux environment. Alternatively, you could also use the pure command-line tool apt-cyg.Install packages¶
Remove packages¶
Cygwin Ssh
Update all packages¶
Note
The
update
option will first download a new version of setup-x86_64.exe
and after that all packages will be updated.![Gnu Gnu](/uploads/1/1/8/9/118946722/480580146.png)
The Cygwin DLL currently works with all recent, commercially released x86_64 versions of Windows, starting with Windows Vista. For more information see the FAQ.

Cygwin version
The most recent version of the Cygwin DLL is 3.2.0.
Installing Cygwin
Install Cygwin by running setup-x86_64.exe
Use the setup program to perform a fresh install or to update an existing installation.
Keep in mind that individual packages in the distribution are updated separately from the DLL so the Cygwin DLL version is not useful as a general Cygwin distribution release number.
Support for Cygwin
For all Cygwin-related questions and observations, please check the resources available at this site, such as the FAQ, the User's Guide and the mailing list archives. If you've exhausted these resources then please send email to an appropriate mailing list. This includes observations about web pages, setup questions, questions about where to find things, questions about why things are done a certain way, questions about the color preferences of Cygwin developers, questions about the meaning of the number 42, etc.
Please send notification of technical problems (bad html, broken links) concerning these web pages to the Cygwin mailing list.
Please do not send personal email with 'quick questions' to individual Cygwin contributors. The Cygwin mailing lists are the places for all questions. Really. I mean it.
32 bit Cygwin
Address space is a very limiting factor for Cygwin. These days, a full 32 bit Cygwin distro is not feasible anymore, and will in all likelihood fail in random places due to an issue with the fork(2) system call.
Therefore we recommend using 32 bit Cygwin only in limited scenarios, with only a minimum of necessary packages installed, and only if there's no way to run 64 bit Cygwin instead.
You have been warned. If you're still sure you really need a 32 bit Cygwin, and there's absolutely no way around it, you may run the setup-x86.exe installer.
