How to cross-compile Google Go (Language) programs:
The machines I work on are typically x64 boxes. A few x86 systems remain in my purview, however. Sometimes I want, on my x64 machine, cross-compile binaries to be used on legacy x86 systems. As finding how to do this with Go (1.x) took longer than necessary, here's the gist of it.
Prerequisite: you already have a Go toolchain for your native architecture installed.
First, install the x86 Go toolchain (compiler, linker, etc):
$ go tool dist install -v cmd/8{a,c,g,l}
cmd/8a
cmd/8c
cmd/8g
cmd/8lSecond, install the x86 Go runtime:
$ GOARCH=386 go tool dist install -v pkg/runtime
pkg/runtime (linux/386)
Now, you can cross-compile with plain
go build by just setting the GOARCH environment variable to the desired target:$ GOARCH=386 go build hello.go
Repeat the same steps with
5{a,c,g,l} and GOARCH=arm, and you'll also be able to cross-compile to ARM.no comments
