OSX10.9 GO1.3交叉編譯

這是一個建立於 的文章，其中的資訊可能已經有所發展或是發生改變。

$GOARCH    目標平台（編譯後的目標平台）的處理器架構（386、amd64、arm）

$GOOS          目標平台（編譯後的目標平台）的作業系統（darwin、freebsd、linux、windows）

各平台的GOOS和GOARCH參考 

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、當前系統：

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

2、下載並安裝GO1.3 

• go1.3.darwin-amd64-osx10.8.pkg

 

執行下面命令：

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

這裡 額外多一個環境變數 CGO_ENABLED 是因為 交叉編譯不支援 CGO，我們這裡禁用它。

這裡並不是重新編譯Go，因為安裝Go的時候，只是編譯了本地系統需要的東西；而需要跨平台交叉編譯，需要在Go中增加對其他平台的支援。所以，有 ./make.bash 這麼一個過程。

執行結果類似如下：

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$ 

編譯後BIN目錄多了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、到原始碼目錄下執行：

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build

不帶前面參數的 go build 只是編譯出開發環境適用的執行檔案。

註：參考網路資料+實驗。
