按照How to successfully build packages for WD My Cloud from source中的介绍，搭建完成WDMyCloud的编译环境
整个 WD MyCloud 的编译项目，可以直接在树莓派中进行编译。只是编译4KB分页（主要用于编译过程）的高版本应用的时候，需要在 raspbian-wheezy 系统中进行编译。
在树莓派中编译 WD MyCloud 代码的时候，由于都是 ARM 环境，因此，不需要 QEMU 的介入，以前由于 QEMU 导致的问题可以规避。
推荐在树莓派4B版本上搭建编译环境，效果来看，速度还是不错的。

这个问题产生的原因是在qemu中创建线程/进程的时候，要求增加CLONE_SYSVSEM标志，否则会出现异常。 go在创建线程/进程的时候，没有指定这个标记。解决方法就是修改src/pkg/runtime/os_linux.c中的void runtime·newosproc(M *mp, void *stk)函数，在flag中增加CLONE_SYSVSEM标志。
这个问题解决起来比较复杂，我们在x86下面直接进行交叉编译的时候，是没办法通过编译的，我们可以通过树莓派下进行编译。树莓派使用2015-05-05-raspbian-wheezy版本的镜像来进行编译。
树莓派这个版本的系统问题在于 wheezy 的源已经被移动地址，因此更新安装软件的时候会报告 404 错误，我们需要手工修改一下源地址。

这个问题产生的原因是在qemu中无法处理编号为 64 的信号(Qemu rejects rt_sigaction of SIGRTMAX (64).)，我们需要忽略这个信号。解决方法就是修改src/pkg/runtime/os_linux.c中的void函数，忽略这个信号。

编译环境安装完成之后，可以成功编译golang-1.3.3，中途可能会失败，失败之后，重新编译可以通过。
编译 golang-1.4 ,由于 golang-1.4 的特殊性，任何高于 golang-1.4 版本的 golang ，都需要 golang-1.4 的编译环境才能开始编译安装！
我们依旧需要在树莓派环境中 raspbian-wheezy && WD MyCloud 编译，如下：

修改完BUG之后编译好的 golang_1.3.3-1.deb(4KB分页)/golang_1.4.3-3.deb(4KB分页)用于编译环境使用，不能在WD MyCloud上使用。
