cygwin install golang

Cygwin is a Unix-like simulation environment running under the Windows operating system. It provides common terminal operation interfaces and related tools under Linux. Golang is an open source programming language launched by Google. Because of its high efficiency, simple syntax, and good readability, it has been widely used in the development of high-performance servers, cloud computing systems and other fields in recent years.

If we want to use Golang in a Cygwin environment, we first need to install Golang. This article will introduce step by step how to install Golang in Cygwin environment.

Step 1: Install Cygwin

First, we need to download and install Cygwin. On the Cygwin official website download page, select the corresponding Windows version and download the installation program. When installing, be sure to check the dependent packages such as "gcc-core", "make", and "zlib-devel" under the "Devel" category, and the "curl", "wget" and other packages under the "Net" category. If you need to use the Git version control tool, you also need to check the "Git" package. After the installation is complete, launch the Cygwin terminal.

Step 2: Download the Golang installation package

Download the corresponding version of the Golang installation package from Golang’s official website. Depending on your local needs, you can choose to download the Linux or Windows version. Here we choose to download the binary installation package of the Linux version. After the download is completed, move the installation package to the specified directory in the Cygwin terminal (here we put it in the /opt directory):

$ cd /opt
$ mv ~/Downloads/go1.16.6.linux-amd64.tar.gz .

Step 3: Unzip the installation package

Use Use the tar command to decompress the Golang installation package:

$ tar -zxvf go1.16.6.linux-amd64.tar.gz

After decompression is completed, we can see a folder named go in the /opt directory, which contains the following files and subfolders:

$ ls /opt/go
api         go.mod      gofmt       misc        src
bin         gofmt.1     lib         pkg         test
doc         goimports   misc.1      README.md   VERSION

Step 4: Set environment variables

To facilitate the use of Golang, we need to add it to the system path. Execute the following command in the Cygwin terminal to add the Golang binary file path to the PATH:

$ echo 'export PATH=$PATH:/opt/go/bin' >> ~/.bashrc
$ source ~/.bashrc

Step 5: Test whether the installation is successful

If Golang is installed successfully, we can enter in the Cygwin terminal Use the following command to check the Golang version number:

$ go version
go version go1.16.6 linux/amd64

If the terminal outputs the go version information, it means that Golang is installed successfully.

So far, we have completed all the steps to install Golang in the Cygwin environment. You can happily start using Golang for programming development.
