Golang source code installation

On golang’s official website, we can download binary files for each platform, but if you need to build golang from source code, it is also supported. This article will introduce the installation and configuration process starting from the source code of golang.

1. Obtain the golang source code

First you need to obtain the golang source code, which can be obtained through the git clone command:

git clone https://go.googlesource.com/go

Among them, https://go. googlesource.com/go is the address of golang source code.

2. Configure the compilation environment

Before installing the compilation environment, you need to install some dependencies. These dependencies may vary from system to system, the following uses Ubuntu system as an example.

sudo apt-get update
sudo apt-get install -y git gcc libc6-dev

Since the golang source code is written in go language, you need to install the go compiler first.

sudo apt-get install -y golang-go

After installing the go compiler, you can start configuring the compilation environment. First, you need to set the two environment variables GO ROOT and GO PATH. Their meanings are as follows:

• GO ROOT: the installation directory of golang.
• GO PATH: golang’s workspace directory.

Add the following content to the .bashrc file (if you are using zsh, add the same content to the .zshrc file):

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

Save changes and reload:

source ~/.bashrc

3. Compile and install

Before compiling, you need to set the following two environment variables:

• GOOS: target operating system.
• GOARCH: Target processor architecture.

Here are some common values:

Environment variables	Value
GOOS	linux, windows, darwin, freebsd, openbsd, plan9
GOARCH	amd64, 386, arm

For example, if you want to compile golang for 64-bit processor architecture on a Linux system, you need to execute the following command:

cd go/src
sudo bash all.bash

This command will download the necessary dependencies and compile all golang packages and tools. The entire compilation process may take some time, depending on machine performance.

4. Verify the installation

After the compilation is completed, you can enter the following command in the terminal to view the installed golang version:

go version

If the following information is output, the installation is successful. ：

go version gox.x.x linux/amd64

Now, you can start writing programs using golang!

5. Summary

This article introduces the basic process of installing golang from source code, including obtaining source code, configuring the compilation environment, compiling and installing, and verifying the installation. Hope this article is helpful to everyone.
