I used 4.9.2, but you can use any version you like. If you’re following this guide at a later date, there will surely be a more recent version of GCC available. To download and extract the latest GCC source code, enter the following commands in the Cygwin terminal. This step is not needed if your machine is directly connected to the Internet.Įxport http_proxy=$HTTP_PROXY https_proxy=$HTTP_PROXY ftp_proxy=$HTTP_PROXY 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. Open a Cygwin terminal, either from the Start menu or by running Cygwin.bat from the Cygwin installation folder.
Alternatively, you can install a new instance of Cygwin in a different folder. 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. I suggest moving the installer to the same folder where you installed Cygwin itself typically C:\cygwin or C:\cygwin64. 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. We’ll add additional packages from the command line later.Īfter the Cygwin installer completes, it’s very important to keep the installer around. When you reach the “Select Packages” step (shown below), don’t bother selecting any packages yet. 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. Cygwin’s setup wizard will walk you through a series of steps. First, download and run either the 32- or 64-bit version of the Cygwin installer, depending on your version of Windows.
