How compatible is the Go language on Linux systems?

Go language has very good compatibility on Linux systems. It can run seamlessly on various Linux distributions and supports processors of different architectures. This article will introduce the compatibility of Go language on Linux systems and demonstrate its powerful applicability through specific code examples.

1. Install the Go language environment

Installing the Go language environment on a Linux system is very simple. You only need to download the corresponding Go binary package and set the relevant environment variables. The following are the steps to install Go language on Ubuntu system:

First, download the Go language binary package suitable for Linux system from the official website https://golang.org/dl/.

Next, unzip the downloaded compressed package and move it to the specified directory, such as /usr/local.

Then, to set the Go language environment variables, you can add the following code in ~/.bashrc or ~/.profile:

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

Finally, to make the environment variables take effect, you can execute source ~/.bashrc or source ~/.profile.

2. Write a simple Go program

Next, let’s write a simple Go program to verify the compatibility of the Go language on the Linux system. Create a file named hello.go with the following content:

package main

import "fmt"

func main() {
    fmt.Println("Hello, Linux!")
}

After saving and exiting the file, use the command line to compile and run the program:

go run hello.go

If you After installing and configuring the Go language environment correctly on the Linux system, you will see the output as Hello, Linux!.

3. Cross-platform compilation of Go programs

Go language supports cross-platform compilation, which can easily generate executable files on different operating systems. Let's demonstrate how to compile a program on a Linux system that can run on a Windows system.

Create a file named hello_windows.go with the following content:

package main

import "fmt"

func main() {
    fmt.Println("Hello, Windows!")
}

Then use the following command to compile and generate an executable file for the Windows system:

GOOS=windows GOARCH=amd64 go build hello_windows.go

After compilation is completed, you will get an executable file named hello_windows.exe, which can be run on Windows systems and output Hello, Windows!.

Conclusion

Through the above examples, we can see that the Go language has very good compatibility on Linux systems, and it performs well in terms of installation, writing programs, and cross-platform compilation. The simplicity, efficiency, and cross-platform features of the Go language make it a very suitable language for developing applications on Linux systems. I hope this article can help readers gain a deeper understanding of the applications and advantages of Go language on Linux systems.
