How To Install Extra Packages In Cygwin
Installing and Updating Cygwin for 64-bit versions of Windows
Run setup-x86_64.exe any time you want to update orinstall a Cygwin package for 64-bit windows. The signature for setup-x86_64.exe can be used to verify the validity ofthis binary.
Installing and Updating Cygwin for 32-bit versions of Windows
Run setup-x86.exe any time you want to update orinstall a Cygwin package for 32-bit windows. The signature for setup-x86.exe can be used to verify the validity ofthis binary.

But here’s a hint: you need to visit the git web page, and install git for Windows. If you prefer a GUI client I recommend tortoise git, you will need to install this separately. INSTALLING EMACS Cygwin. The first task is to install Cygwin. Cygwin is a repository of GNU tools for Microsoft Windows. Cygwin has a nice setup program that downloads and installs the necessary Cygwin packages for you. Open the Cygwin, page in your web browser. Click on the 'setup-x8664.exe' (64-bit installation) or 'setup-x86.exe' (32-bit installation) link to download the appropriate setup program from the primary Cygwin server. Save it to the directory that you would like to store the downloaded packages in (e.g. Install a set of Cygwin packages required for building GCC. From within Cygwin, download the GCC source code, build and install it. Test the new GCC compiler in C14 mode using the -std=c14 option. Update: As a commenter points out, you can also install native GCC compilers from the MinGW-w64 project without needing Cygwin. # Cygwin 1.7's setup.exe introduces a -P switch which takes a list of extra packages. Setup needs to be run from a cmd window, not from bash. Drag the shortcut to setup.exe from your Desktop into the cmd window. # install all the packages in cygwin: cd path/to/downloads/cygwin. The command is provided by a package called cabal-install. It can be installed using ghcup, and cabal is also part of the Haskell Platform, other methods are listed at Distributions. The Cabal-Install page explains how to use cabal. If you so wish, you can still install packages manually - see the section below. Installing packages manually.
The key used to sign setup binaries has been updated. During the transitionperiod, signatures are made using both old (676041BA) and new (1A698DE9E2E56300)public keys here.See thismail for more details.General installation notes
When installing packages for the first time, the setup programdoes not install every package. Only the minimal base packagesfrom the Cygwin distribution are installed by default, which takes up about 100 MB.
Clicking on categories and packages in the setup program package installationscreen allows you to select what is installed or updated.
Individual packages like bash, gcc, less, etc.are released independently of the Cygwin DLL, so the Cygwin DLL version is notuseful as a general Cygwin release number. The setup programtracks the versions of all installed components and provides the mechanismfor installing or updating everything available from this site forCygwin.
Once you've installed your desired subset of the Cygwin distribution,the setup program will remember what you selected, so re-running itwill update your system with any new package releases.
On Windows Vista and later, the setup program will check bydefault if it runs with administrative privileges and, if not, will tryto elevate the process. If you want to avoid this behaviour and installunder an unprivileged account just for your own usage, runsetup with the --no-admin option.
Q: How do I add a package to my existing Cygwin installation?
A: Run the setup program and select the package you want to add.
Tip: if you don't want to also upgrade existing packages, select 'Keep' at thetop-right of the package chooser page.
Q: Is there a command-line installer?
A: Yes and no. The setup program understandscommand-linearguments which allow you to control its behavior and chooseindividual packages to install. While this provides some functionalitysimilar to such tools as apt-get or yum it is not asfull-featured as those package managers.
Q: Why not use apt, yum, myfavourite package manager, etc.?
A: The basic reason for not using a more full-featured package manager is thatsuch a program would need full access to all of Cygwin's POSIX functionality. Thatis, however, difficult to provide in a Cygwin-free environment, such as exists onfirst installation. Additionally, Windows does not easily allow overwriting ofin-use executables so installing a new version of the Cygwin DLL while a packagemanager is using the DLL is problematic.
Q: How do I install everything?
A: You do not want to do this! This will install an enormous number of packagesthat you will never use, including debuginfo and source for every package.
If you really must do this, clicking on the 'Default' label next to the'All' category to change it to 'Install' will mark every Cygwin package forinstallation. Be advised that this will download and install tens of gigabytesof files to your computer.

Cygwin Install Additional Packages
Cygwin is a collection of GNU and Open Source tools that provide a Linux-like environment for Windows: using it we can install and use llvm (which includes the GCC compilers), Clang (which includes Clang compilers), GDB (a debugger used by both compilers), and make/cmake (tools that which we use to specify how to build -compile and link- C++ programs). Cygwin and it toolset occupy about 14 GB on disk.
In this handout you will download and install the Cygwin toolset; in the next you will download a version of CLion, an Integrated Development Environment (IDE) for using these tools (or you can choose to use these tools via a command-line).
You may want to print these instructions before proceeding, so that you can refer to them while downloading and installing Cygwin and its toolset. Or, just keep this document in your browser. You should read each step completely, before performing the action that it describes.
