Build For A Specific OS and Architecture

Go programs can run anywhere, but you've got to create builds specific to each operating system and architecture. This can be done when building by specifying the GOOS and GOARCH environment variables.

For example, if you'd like to build a 32-bit Linux distribution:

GOOS=linux GOARCH=386 go build -o linux_386_build

The GOOS value specifies the operating system as Linux and the GOARCH value of 386 specifies a 32-bit architecture.

The plethora of GOOS and GOARCH options can be found here.
