11/8/2019 Install Cygwin Windows 10
Several modern C++ features are currently missing from Visual Studio Express, and from the system GCC compiler provided with many of today’s Linux distributions. Generic lambdas – also known as polymorphic lambdas – are one such feature. This feature is, however, available in the latest versions of GCC and Clang.
The following guide will help you install the latest GCC on Windows, so you can experiment with generic lambdas and other cutting-edge C++ features. You’ll need to compile GCC from sources, but that’s not a problem. Depending on the speed of your machine, you can have the latest GCC up and running in as little as 15 minutes.
Now that you have Cygwin downloaded. The next step is to install it. Go to your Desktop, click open the Cygwin Setup folder and click on setup-x8664.exe. (If you are running Windows 10 Professional, you should right-click on setup-x8664.exe and select 'Run As Administrator', if you. Sep 28, 2014 Installing Cygwin. To install Cygwin, head to the official site of Cygwin and download the executable depending on your system preference (32-bit or 64-bit). The executable itself is small as it downloads all the required packages while installing the software. Once you have downloaded the Cygwin installer, launch the installer as the Administrator. Open the executable Cygwin setup file. Run the set-up as normal. Click on Next on the Cygwin Setup screen. When choosing Installation Type, select Install from Internet (default). How to Install Cygwin on Windows 10 Cygwin is an open source project which provides the functionality of Linux distribution on the Windows platform. This tutorial will teach you how you can install Cygwin on Windows 10.
The steps are:
[Update: As a commenter points out, you can also install native GCC compilers from the MinGW-w64 project without needing Cygwin.]
1. Install Cygwin
First, download and run either the 32- or 64-bit version of the Cygwin installer, depending on your version of Windows. Cygwin’s setup wizard will walk you through a series of steps. If your machine is located behind a proxy server, make sure to check “Use Internet Explorer Proxy Settings” when you get to the “Select Your Internet Connection” step.
When you reach the “Select Packages” step (shown below), don’t bother selecting any packages yet. Just go ahead and click Next. We’ll add additional packages from the command line later.
After the Cygwin installer completes, it’s very important to keep the installer around. The installer is an executable named either
setup-x86.exe or setup-x86_64.exe , and you’ll need it to add or remove Cygwin packages in the future. I suggest moving the installer to the same folder where you installed Cygwin itself; typically C:cygwin or C:cygwin64 .
If you already have Cygwin installed, it’s a good idea to re-run the installer to make sure it has the latest available packages. Alternatively, you can install a new instance of Cygwin in a different folder.
![]() 2. Install Required Cygwin Packages
Next, you’ll need to add several packages to Cygwin. You can add them all in one fell swoop. Just open a Command Prompt (in Windows), navigate to the folder where the Cygwin installer is located, and run the following command:
A window will pop up and download all the required packages along with their dependencies.
At this point, you now have a working GCC compiler on your system. It’s not the latest version of GCC; it’s whatever version the Cygwin maintainers chose as their system compiler. At the time of writing, that’s GCC 4.8.3. To get a more recent version of GCC, you’ll have to compile it yourself, using the GCC compiler you already have.
3. Download, Build and Install the Latest GCC
Open a Cygwin terminal, either from the Start menu or by running
Cygwin.bat from the Cygwin installation folder.
If your machine is located behind a proxy server, you must run the following command from the Cygwin terminal before proceeding – otherwise,
wget won’t work. This step is not needed if your machine is directly connected to the Internet.
To download and extract the latest GCC source code, enter the following commands in the Cygwin terminal. If you’re following this guide at a later date, there will surely be a more recent version of GCC available. I used 4.9.2, but you can use any version you like. Keep in mind, though, that it’s always best to have the latest Cygwin packages installed when building the latest GCC. Be patient with the
tar command; it takes several minutes.
That will create a subdirectory named
gcc-4.9.2 . Next, we’ll configure our GCC build. As the GCC documentation recommends, it’s best to configure and build GCC in another directory outsidegcc-4.9.2 , so that’s what we’ll do.
The pets are not supposed to be kept for long, nor are Blonds allowed to interact sexually with them; but one Blond, named Iason Mink, has kept a pet for years. The populace is almost entirely male and is based on hair color; anyone silver/blond are the elite, with dark/black hair as the bottom of society, often known as 'mongrels'. On planet Amoi, a great society has developed, creating a computerized city called Tanagura, ruled by supercomputer Jupiter. Ai no kusabi episode 1. Mink is also rumored to sleep with his pet named Riki and refuses to let go of him; despite Jupiter's disapproval. Blonds have 'pets', which are usually young boys kept for a few years, who are especially made for performing sexual actions for the Blond's voyeurism entertainment.
Here’s a description of the command-line options passed to
configure :
We’re not going to build a new Binutils, which GCC relies on, because the existing Binutils provided by Cygwin is already quite recent. We’re also skipping a couple of packages, namely ISL and CLooG, which means that the new compiler won’t be able to use any of the Graphite loop optimizations.
Next, we’ll actually build the new GCC compiler suite, including C, C++ and the standard C++ library. This is the longest step.
The
-j4 option lets the build process spawn up to four child processes in parallel. If your machine’s CPU has at least four hardware threads, this option makes the build process run significantly faster. The main downside is that it jumbles the output messages generated during the build process. If your CPU has even more hardware threads, you can specify a higher number with -j . For comparison, I tried various numbers on a Xeon-based machine having 12 hardware threads, and got the following build times:
Be warned: I encountered a segmentation fault the first time I ran with
-j4 . Bad luck on my part. If that happens to you, running the same command a second time should allow the build process to finish successfully. Also, when specifying higher numbers with -j , there are often strange error messages at the end of the build process involving “jobserver tokens”, but they’re harmless.
Once that’s finished, install the new compiler:
This installs several executables to
/usr/local/bin ; it installs the standard C++ library’s include files to /usr/local/include/c++/4.9.2 ; and it installs the static standard C++ library to /usr/local/lib , among other things. Interestingly, it does not install a new standard C library! The new compiler will continue to use the existing system C library that came with Cygwin.
If, later, you decide to uninstall the new GCC compiler, you have several options:
4. Test the New Compiler
All right, let’s compile some code that uses generic lambdas! Generic lambdas are part of the C++14 standard. They let you pass arguments to lambda functions as
auto (or any templated type), like the one highlighted below. Create a file named test.cpp with the following contents:
You can add files to your home directory in Cygwin using any Windows-based text editor; just save them to the folder
C:cygwin64homeJeff (or similar) in Windows.
First, let’s see what happens when we try to compile it using the system GCC compiler provided by Cygwin:
If the system compiler version is less than 4.9, compilation will fail:
Now, let’s try it again using our freshly built GCC compiler. The new compiler is already configured to locate its include files in
/usr/local/include/c++/4.9.2 and its static libraries in /usr/local/lib . All we need to do is run it:
It works!

The above command makes no sense. It shouldn't start with
cd as you are already in the correct directory.
Try the following commands (which work here):

Note:
The most recent version of the Cygwin DLL is 2.5.0. Install it by running setup-x86.exe (32-bit installation) or setup-x86_64.exe (64-bit installation).
