golang arm installation

With the popularity of ARM architecture processors, more and more developers are beginning to pay attention to how to develop on the ARM platform. As an efficient and concurrent programming language, Golang has gradually become a popular choice on the ARM platform. This article will introduce how to install Golang on ARM systems.

1. Download the Golang software package

First, we need to go to the Golang official website to download the Golang software package corresponding to the ARM architecture. Currently, the official website provides multiple versions of Golang software packages. We need to choose the software package that suits our system and architecture to download.

According to official documents, the currently officially supported ARM architectures are ARMv6, ARMv7 and ARM64. We can check the currently used system architecture through the following command:

$ uname -m

If it is ARMv6 or ARMv7, it is recommended to download a version before Golang 1.16; if it is ARM64, it is recommended to download Golang 1.16 or higher.

In this example, we will be using a Raspberry Pi 4 Model B, so the download is Golang version 1.16.

2. Install the Golang software package

After the download is completed, we need to unzip the Golang software package to the specified directory. Here, we choose to extract the software package to the /usr/local directory. /usr/local here is a convention, and third-party software is usually installed in this directory.

Execute the following command to decompress the software package to the /usr/local directory:

$ sudo tar -C /usr/local -xzf go1.16.linux-armv6l.tar.gz

After the decompression is completed, a go directory will be generated in the /usr/local directory, which contains Golang related files. In this directory, we can see the following files and directories:

go/
├── api
├── bin
├── lib
├── pkg
└── src

Among them, the bin, lib and pkg directories are some files and libraries required by the Golang compiler; the src directory contains all standard library source codes ; The api directory contains API documents for all versions of Golang.

Next, we need to configure Golang-related environment variables so that we can use Golang in the terminal.

3. Set Golang environment variables

Before setting Golang environment variables, we first need to confirm whether the following two paths are included in the current user's PATH variable:

/usr/local/go/bin
$HOME/go/bin

If neither of the above two paths are included in the PATH variable, you can add the following two lines of code to the ~/.bashrc file:

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

Note: If you are using zsh, please add the above code to the ~/.zshrc file.

Once the setup is completed, execute the following command directly in the terminal to see the Golang version installed in the current system:

$ go version
go version go1.16 linux/arm

At this point, we have successfully installed Golang on the ARM system. In the following development work, you can safely use Golang for program development.
