Are Golang binaries portable?

Question

Suppose I\'m a primarily Linux user, but I\'m developing an application in Go that I want to be cross platform. I\'ve searched around, but I can\'t seem to find information

Answer 1

1. Yes it will; this is true of basically all binaries compiled for 64-bit Linux, not just those written in Go (except for shared libraries, which Go doesn't rely on)
2. You can set the GOOS and GOARCH environment variables before building: GOOS=windows GOARCH=386 go build (or go install or whatever), etc
3. By default a binary will be built for the system you're running, but this isn't necessary - see 2
