原文链接： Go 交叉编译

测试：

package main
import (
	"fmt"
	"runtime"
)
func main() {
    fmt.Printf("OS: %s\nArchitecture: %s\n", runtime.GOOS, runtime.GOARCH)
}

编译： $ GOOS=darwin GOARCH=386 go build test.go

使用tag和文件后缀的方式实现。

tag方式
tag遵循一下规则

a build tag is evaluated as the OR of space-separated options
each option evaluates as the AND of its comma-separated terms
each term is an alphanumeric word or, preceded by !, its negation

在文件的头部增加tag:
// +build darwin freebsd netbsd openbsd

可以有多个tag,之间是AND的关系

// +build linux darwin
// +build 386

注意tag和package中间需要有空行分隔，下面的例子是不对的:
// +build !linux
package main // wrong

文件后缀方式 只能在build平台上进行编译

以_$GOOS.go为后缀的文件只在此平台上编译，其它平台上编译时就当此文件不存在。完整的后缀如：
$GOOS$GOARCH.go

如syscall_linux_amd64.go,syscall_windows_386.go,syscall_windows.go等。
