Next, create a Hello, World! Go file in your preferred text editor:Īdd the following text into your hello.go file: You can do this by creating a go.mod file with the go mod init command: When importing packages, you have to manage the dependencies through the code’s own module.

Then move into the directory you just created: Now that Go is installed, you can try creating your Hello, World!.įirst, create a new directory for your Go workspace, which is where Go will build its files: Go installed, as described in How to Install Go on Ubuntu 20.04.One Ubuntu 20.04 server set up by following the Ubuntu 20.04 initial server setup guide, including a sudo non-root user and a firewall.When you’re done, you’ll know how to build executables for Windows and macOS, as well as other platforms you want to support. Then you’ll build an executable for a different architecture, and automate the build process to create executables for multiple platforms. Then you’ll manually build and install the executable so you can be familiar with the process. In this tutorial, you’ll use Go’s tools to obtain a package from version control and automatically install its executable. This makes testing and package distribution much easier, because you don’t need to have access to a specific platform in order to distribute your package for it. One of Go’s most powerful features is the ability to cross-build executables for any Go-supported foreign platform.

The Go programming language comes with a rich toolchain that makes obtaining packages and building executables incredibly easy.
