== Cross-Compilation
Go supports cross-compilation. The environment variables GOOS (e.g. linux,
netbsd, …) and GOARCH (amd64, 386, arm) influence the resulting binary.
For example, to compile helloworld for linux_386, use:
~/gocode/src/helloworld $ GOARCH=386 go build
~/gocode/src/helloworld $ file helloworld
helloworld: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
statically linked, not stripped
If you get an error message like this:
~/gocode/src/helloworld $ GOARCH=386 go build
go build runtime: linux/386 must be bootstrapped using make.bash
…you are missing the appropriate golang-go-$GOOS-$GOARCH debian package,
i.e. golang-go-linux-386 in this case.
