OSX10.9 GO1.3交叉编译

$GOARCH    目标平台（编译后的目标平台）的处理器架构（386、amd64、arm）

$GOOS          目标平台（编译后的目标平台）的操作系统（darwin、freebsd、linux、windows）

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

1、当前系统：

fuyundeMacBook-Pro:src fuyun$ uname -a

Darwin fuyundeMacBook-Pro.local 13.2.0 Darwin Kernel Version 13.2.0: Thu Apr 17 23:03:13 PDT 2014; root:xnu-2422.100.13~1/RELEASE_X86_64 x86_64

• go1.3.darwin-amd64-osx10.8.pkg

执行下面命令：

$ cd /usr/local/go/src
$ sudo CGO_ENABLED=0 GOOS=linux GOARCH=amd64 ./make.bash

这里 额外多一个环境变量 CGO_ENABLED 是因为 交叉编译不支持 CGO，我们这里禁用它。

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：

fuyundeMacBook-Pro:pkg fuyun$ cd /usr/local/go/src

fuyundeMacBook-Pro:src fuyun$ sudo CGO_ENABLED=0 GOOS=linux GOARCH=amd64 ./make.bash

Installed Go for linux/amd64 in /usr/local/go

Installed commands in /usr/local/go/bin

fuyundeMacBook-Pro:src fuyun$ 

编译后BIN目录多了LINUX_AMD64所需要的工具

fuyundeMacBook-Pro:bin fuyun$ pwd

/usr/local/go/bin

fuyundeMacBook-Pro:bin fuyun$ ls

go godoc  gofmt        linux_amd64       windows_amd64

3、到源代码目录下执行：

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build

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。
