go项目使用gox交叉编译,生成跨平台的可执行文件

【第一次安装】

1.安装gox

$ go get github.com/mitchellh/gox
$ cd $GOPATH/src/github.com/mitchellh/gox
$ go build

2.编辑~/.bash_profile（bsh） 或者~/.zshrc（zsh） 添加一行:

alias gox="$GOPATH/src/github.com/mitchellh/gox/gox"

新开终端，让设置生效。

3.生成本地工具链(如果go版本升级,比如从1.3.3升级到1.4，需要重新运行这个命令先)

$ gox -build-toolchain

【交叉编译项目】

1.比如有一个项目的目录在$GPATH/src/hello

$cd $GPATH/src/hello
$gox
Number of parallel builds: 8


-->      darwin/386: hello
-->    darwin/amd64: hello
-->       linux/386: hello
-->     linux/amd64: hello
-->       linux/arm: hello
-->     freebsd/386: hello
-->   freebsd/amd64: hello
-->     openbsd/386: hello
-->   openbsd/amd64: hello
-->     windows/386: hello
-->   windows/amd64: hello
-->     freebsd/arm: hello
-->      netbsd/386: hello
-->    netbsd/amd64: hello
-->      netbsd/arm: hello
-->       plan9/386: hello
-->   dragonfly/386: hello
--> dragonfly/amd64: hello
-->   solaris/amd64: hello

对应生成下面的各平台文件:

$ll
total 16768
drwxr-xr-x  23 wenke  staff     782 12 30 19:42 .
drwxr-xr-x   7 wenke  staff     238 12 28 16:21 ..
-rw-r--r--   1 wenke  staff      54 12 28 16:22 hello.go
-rwxr-xr-x   1 wenke  staff  381420 12 30 19:42 hello_darwin_386
-rwxr-xr-x   1 wenke  staff  467040 12 30 19:42 hello_darwin_amd64

-rwxr-xr-x   1 wenke  staff  469424 12 30 19:42 hello_dragonfly_amd64
-rwxr-xr-x   1 wenke  staff  381296 12 30 19:42 hello_freebsd_386
-rwxr-xr-x   1 wenke  staff  469240 12 30 19:42 hello_freebsd_amd64
-rwxr-xr-x   1 wenke  staff  408336 12 30 19:42 hello_freebsd_arm
-rwxr-xr-x   1 wenke  staff  390768 12 30 19:42 hello_linux_386
-rwxr-xr-x   1 wenke  staff  475888 12 30 19:42 hello_linux_amd64
-rwxr-xr-x   1 wenke  staff  413856 12 30 19:42 hello_linux_arm
-rwxr-xr-x   1 wenke  staff  386440 12 30 19:42 hello_netbsd_386
-rwxr-xr-x   1 wenke  staff  470448 12 30 19:42 hello_netbsd_amd64
-rwxr-xr-x   1 wenke  staff  409224 12 30 19:42 hello_netbsd_arm
-rwxr-xr-x   1 wenke  staff  381696 12 30 19:42 hello_openbsd_386
-rwxr-xr-x   1 wenke  staff  469648 12 30 19:42 hello_openbsd_amd64
-rwxr-xr-x   1 wenke  staff  365441 12 30 19:42 hello_plan9_386
-rwxr-xr-x   1 wenke  staff  490296 12 30 19:42 hello_solaris_amd64
-rwxr-xr-x   1 wenke  staff  385536 12 30 19:42 hello_windows_386.exe
-rwxr-xr-x   1 wenke  staff  466944 12 30 19:42 hello_windows_amd64.exe

2.只生成mac和linux平台下的文件

$gox -os "darwin linux"
Number of parallel builds: 8

-->      darwin/386: hello
-->    darwin/amd64: hello
-->       linux/386: hello
-->     linux/amd64: hello
-->       linux/arm: hello

3. 只生成linux平台amd64的文件

$gox -osarch="linux/amd64"
Number of parallel builds: 8

-->     linux/amd64: hello
