各平台的GOOS和GOARCH参考
OS ARCH OS version
linux 386 / amd64 / arm >= Linux 2.6
darwin 386 / amd64 OS X (Snow Leopard + Lion)
freebsd 386 / amd64 >= FreeBSD 7
windows 386 / amd64 >= Windows 2000
$ cd /usr/local/go/src
$ sudo CGO_ENABLED=0 GOOS=linux GOARCH=amd64 ./make.bash
这里并不是重新编译Go,因为安装Go的时候,只是编译了本地系统需要的东西;而需要跨平台交叉编译,需要在Go中增加对其他平台的支持。所以,有 ./make.bash 这么一个过程。
执行结果类似如下:
sudo CGO_ENABLED=0 GOOS=linux GOARCH=amd64 ./make.bash

三、编译对应平台下的执行文件
到源代码目录下执行:
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build sina.go
不带前面参数的 go build 只是编译出开发环境适用的执行文件。
