• Binutils
• Gcc4-core
• gcc4-gcc
• Libwrap-devel

So when installing Cygwin, choose to install the software.

We can download the Cygwin installer on the official website of Cygwin, the address is:

http://www.cygwin.com/

or download the installer directly by using the download connection:

Http://www.cygwin.com/setup.exe

After the download is complete, run the Setup.exe program and the installation screen appears. Directly point to "next", the Installation Mode dialog box appears as shown in:

We see three types of installation modes:

• Install from the Internet, this mode is installed directly from the Internet, suitable for fast speed situation;
• Download without installing, this mode only downloads the Cygwin component package from the Internet, but does not install;
• Install from local Directory, this mode corresponds to the second mode above, and when your Cygwin component package has been downloaded locally, you can use this mode to install Cygwin locally.

Choose from the above three modes suitable for your installation mode, here we choose the first installation mode, directly from the Internet installation, of course, while downloading, Cygwin components are also saved to the local, so that later can be installed again. When selected, click Next,

This step selects the installation directory for the Cygwin, as well as some parameter settings. The default installation location is C:\cygwin\, you can also choose your own installation directory, and then choose "Next",

This step we can select the installation process from the Internet Download Cygwin component package save location, after selecting, click "Next",

This step select the way to connect, select your connection mode, and then click Next, the Select Download Site dialog box appears, as shown in,

In this step, we need to note that in order to get the fastest download speed, we first look for the address of the Cygwin Chinese image in the list: http://www.cygwin.cn, if found, select this address; If you cannot find this address, enter the address of the Chinese mirror manually: http ://www.cygwin.cn/pub/, then click "Add" and then select it in the list. After selecting Done, click "Next",

This step, we choose to download the installed component package, in order to enable our installed Cygwin to compile the program, we need to install the GCC compiler, by default, GCC will not be installed, we need to select it to install. In order to install GCC, we use the mouse to click on the "Devel" branch in the component list, where there are many components, we must:

Binutils
Gcc
Gcc-mingw
Gdb

Mouse click on the front of the component of the loop button, the build date will appear, we choose the latest version of the installation, is selected after the four categories of components:

Binutils components	GCC components
GCC-MINGW components	GDB components

After the selection, we choose the next step, enter the installation process, as shown in,

The time of installation depends on the components you select and the network conditions. After the installation is complete, the installer will prompt you to create the Cygwin icon on the desktop and click Finish to exit Setup.
