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 381536 12 30 19:42 hello_dragonfly_386 -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
