How do I build portable Go binaries for different operating systems and architectures?

Portability of Go Binaries

Go binaries are designed to be cross-platform, allowing developers to build applications that can run on multiple operating systems and architectures. However, achieving portability across different configurations requires an understanding of Go's linking and compilation process.

Q1: Portability of amd64 Linux Binaries

A: Yes, an amd64 binary compiled on an Ubuntu system will run on any other 64-bit Ubuntu/Debian system without modification. This is because Linux uses a common set of system libraries for 64-bit applications, ensuring binary compatibility across distributions.

Q2: Building 32-bit Binaries for Debianlikes

A: To create an x86_64 binary that will run on both 64-bit and 32-bit Debianlikes, use the following command:

GOOS=windows GOARCH=386 go build

Setting GOOS to "windows" and GOARCH to "386" forces the build process to generate a 32-bit executable.

Q3: Ensuring x86_64 Executables on Windows

A: Building a binary on a 64-bit Windows system doesn't automatically guarantee that it will target the x86_64 architecture. To ensure an x86_64 executable, specify the -target flag when building:

go build -target=amd64

This flag explicitly sets the target architecture for the compiled binary, regardless of the host operating system.
