Detailed explanation of Hongmeng system configuration Go language installation method

Hongmeng system is an operating system independently developed by Huawei. In order to allow developers to write applications more conveniently, Hongmeng system provides It supports multiple programming languages, including Go language. Go language is an efficient and easy-to-use programming language suitable for developing various applications. This article will introduce in detail how to configure the installation method of Go language on Hongmeng system, as well as specific code examples.

1. Installation preparation
Before installing the Go language, you first need to ensure that your Hongmeng system is connected to the Internet in order to download the files required for installation. In addition, you also need to prepare a development environment that supports Go language programming, such as a complete terminal command line tool. Next, we will start configuring the Go language installation.

2. Download the installation package
Enter the following command in the Hongmeng system terminal to download the Go language installation package:

wget https://golang.org/dl/go1.17.1-linux-arm64.tar.gz

Here, take Go language version 1.17.1 as an example. You can also choose other versions according to your needs. After the download is complete, use the following command to decompress the installation package:

tar -C /usr/local -xzf go1.17.1-linux-arm64.tar.gz

This will install the Go language in the /usr/local directory. You can also choose other directories for installation.

3. Configure environment variables
Next, you need to configure the environment variables of the Go language so that the system can correctly identify the installation path of the Go language. Enter the following command in the terminal:

export PATH=$PATH:/usr/local/go/bin
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

Here, add the executable file path of the Go language to the PATH of the system, and set the GOPATH to store the working directory of the Go language. You can adjust it according to the actual situation.

4. Test installation
After completing the above configuration, you can use the following command to test whether the installation of Go language is successful:

go version

If the version information of Go language is displayed, it means Go language Successful installation. Now, you can start writing applications in Go language.

5. Sample Code
The following is a simple Go language sample code for printing a welcome statement:

package main

import "fmt"

func main() {
    fmt.Println("欢迎使用Go语言！")
}

You can use a text editor to save the above code as hello. go file, and then use the following commands to compile and run the program:

go run hello.go

So you can run your first Go language program on the Hongmeng system. I hope this article will help you configure the installation method of Go language on Hongmeng system. Happy programming!
