如果你现在使用的系统架构不是x86,amd等架构，想要编译一版docker是何等的困难，官方提供的是在容器里编译，编译过程去官方仓库拉取需要的image层，可是在像mips这样的架构下，官方的镜像层是不可能拉取来使用的，一定会报错，那怎么办？于是本人尝试下载docker的github源码来编译，过程如下：

方法一.编译rpm包(推荐使用这种方法)

1.下载相应的rpm包

$wget https://mirrors.ustc.edu.cn/fedora/updates/25/SRPMS/d/docker-1.12.6-6.gitae7d637.fc25.src.rpm

如果上命令无法下载，可以去koji或者rpm search搜索下载

2.安装下载的xxx.src.rpm

$rpm -ivh xxx.src.rpm

3.进入rpmbuild/SPECS目录，就会看到有个文件docker.spec

$cd ~/rpmbuild/SPECS

4.执行编译，修改出错，再编译，这里面改错，一定会用的打patch的方法，见本人另一篇博客《rpmbuild编译一个软件时如何加入自己的补丁patch 》

$rpmbuild -ba docker.spec

具体内容没保存日志，略

方法二.编译github源码

• 安装依赖包

#yum install -y glibc-static btrfs-progs-devel device-mapper-devel golang libselinux-static libsepol-static

#yum install -y libuuid-devel libattr-devel zlib-devel libacl-devel e2fsprogs-devel libb

• 开始编译

#cd  docker目录

#sh -x ./hack/make.sh dynbinary  ;;动态编译，小红帽系列的操作系统都得动态编译，静态编的话是sh -x ./hack/make.sh binary

    ' github.com/docker/docker/cmd/docker
# github.com/docker/docker/pkg/system

.gopath/src/github.com/docker/docker/pkg/signal/signal_linux.go:41: undefined: syscall.SIGUNUSED

解决办法
1.uint64(s.Rdev)
2.syscall.SIGSTKFLT-->16
3.syscall.SIGUNUSED-->31

继续编译

解决办法
1.创建 vendor/github.com/boltdb/bolt/bolt_mips64le.go文件，内容如下：
    [bolt_mips64le.go]
    // +build mips64le

    package bolt

    // maxMapSize represents the largest mmap size supported by Bolt.
    const maxMapSize = 0x3FFFFFFF // 1GB
    // maxAllocSize is the size used when creating array pointers.
    const maxAllocSize = 0x3FFFFFFF

    // Are unaligned load/stores broken on this arch?
    var brokenUnaligned = false
2.创建vendor/github.com/vishvananda/netns/netns_linux_mips64le.go文件，内容如下
    [netns_linux_mips64le.go]
    // +build linux,mips64le

    package netns

    const (
            SYS_SETNS                  = 5303
    )
3.将handle_linux.go  39，65行 stat.Dev-->uint64(stat.Dev)
4.x509.go按照patch修改，具体网址忘记了，内容如下，去掉P224的地方：
    diff --git a/vendor/src/github.com/google/certificate-transparency/go/x509/x509.go b/vendor/src/github.com/google/certificate-transparency/go/x509/x509.go

            s := make([]byte, len(ca))
            var lens int
            for ; lens < len(ca); lens++ {
                    if ca[lens] == 0 {

                    s[lens] = uint8(ca[lens])
            }
            return string(s[0:lens])
    }

继续编译

.gopath/src/github.com/docker/docker/daemon/graphdriver/devmapper/deviceset.go:1752: cannot use sysSt.Dev (type uint32) as type uint64 in argument to minor

1.将dev-->uint64(dev)转换为64位，将sysSt.Dev-->uint64(sysSt.Dev)

继续编译，编译成功

#cd bundles

#tree

会出现下图的结果

此时，到dynbinary-client下执行docker -v会有如下图输出

到这一步，我疑惑，服务怎么启动，docker 守护进程怎么起，看了许多，X86平台的很多帖子都说到这一步就成功了，成功何在？？

感情是替换原来的docker二进制文件，本人试了，结果很遗憾，只能停留在这一步，希望有人解决这个疑惑。
