Can Golang Binaries Run on Different Operating Systems?

Are Golang Binaries Portable?

In the realm of programming, portability is key for reaching a broader audience. As a primarily Linux user, you may wonder if Golang binaries you create have the ability to run seamlessly on various platforms. This article delves into the portability of Golang binaries and provides answers to your specific questions.

Question 1: Compatibility on 64-bit Ubuntu/Debian Systems

Yes, Golang binaries compiled on your 64-bit Ubuntu system will generally run on other 64-bit Ubuntu/Debian systems. This applies to binaries written in most languages, not just Go. The exception to this rule is shared libraries, which are not heavily utilized in Go programs.

Question 2: Building x86_64 Binaries for 32-bit Debianlikes

To achieve this, you can set the GOOS and GOARCH environment variables before compiling your binary. Use the following command:

GOOS=windows GOARCH=386 go build

This will generate a binary that runs on x86_64 systems.

Question 3: Ensuring x86_64 Binaries on Windows

By default, Go binaries are built for the system you're running on. However, you can override this by setting the GOOS and GOARCH variables as described in Question 2. Even if your Windows system is 64-bit, you can create x86_64 binaries using the same command:

GOOS=windows GOARCH=386 go build

In conclusion, Golang binaries compiled for a specific platform are generally portable to other systems running the same architecture. By adjusting the GOOS and GOARCH environment variables, you can further enhance the portability of your Go programs and ensure their compatibility across various platforms.
