深海游弋的鱼 – 默默的点滴

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。

$ sed -i "s/wheezy/oldoldstable/g" /etc/apt/source.list

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 runtime·setsig(int32 i, GoSighandler *fn, bool restart)函数，忽略这个信号。

# BUG `fatal error: rt_sigaction failure`
$ sed -i "s/runtime·rt_sigaction(i, \&sa, nil, sizeof(sa.sa_mask)) != 0/runtime·rt_sigaction(i, \&sa, nil, sizeof(sa.sa_mask)) != 0 \&\& i != 64/g" src/pkg/runtime/os_linux.c

完成之后,拷贝到编译环境中并执行安装

$ dpkg -i golang-src_1.3.3-1*_armhf.deb

$ dpkg -i golang-doc_1.3.3-1*_all.deb

$ dpkg -i golang-go-linux-arm_1.3.3-1*_armhf.deb

$ dpkg -i golang-go_1.3.3-1*_armhf.deb

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！

$ DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -d -b -uc

完成之后,拷贝到编译环境中并执行安装

$ dpkg -i golang-src_1.4.3-3_armhf.deb	 	 

$ dpkg -i golang-go_1.4.3-3_armhf.deb	 	 

$ dpkg -i golang-doc_1.4.3-3_all.deb	 	 

$ dpkg -i golang-go-linux-arm_1.4.3-3_armhf.deb	 	 

$ dpkg -i golang_1.4.3-3_all.deb

$ dpkg -i golang-src_1.4.3-3_armhf.deb

$ dpkg -i golang-go_1.4.3-3_armhf.deb

$ dpkg -i golang-doc_1.4.3-3_all.deb

$ dpkg -i golang-go-linux-arm_1.4.3-3_armhf.deb

$ dpkg -i golang_1.4.3-3_all.deb

我们需要在 golang 1.4.3 环境中继续编译,可以在 golang 1.3.3 中运行：

$ cd ~/wdmc-build/64k-wheezy
 
$ sudo chroot build
 
$ mount -t proc none /proc
$ mount -t devtmpfs none /dev
$ mount -t devpts none /dev/pts
 
$ export DEBIAN_FRONTEND=noninteractive
$ export DEBCONF_NONINTERACTIVE_SEEN=true
$ export LC_ALL=C
$ export LANGUAGE=C
$ export LANG=C
$ export DEB_CFLAGS_APPEND='-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE'
$ export DEB_BUILD_OPTIONS=nocheck

$ cd root

$ git clone https://github.com/git-lfs/git-lfs.git

# 或者本站下载一份拷贝 wget https://www.mobibrw.com/wp-content/uploads/2019/11/git-lfs.zip

$ git checkout v1.2.1

$ DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -d -b -uc

$ cd ~/wdmc-build/64k-wheezy

$ sudo chroot build

$ mount -t proc none /proc

$ mount -t devtmpfs none /dev

$ mount -t devpts none /dev/pts

$ export DEBIAN_FRONTEND=noninteractive

$ export DEBCONF_NONINTERACTIVE_SEEN=true

$ export LC_ALL=C

$ export LANGUAGE=C

$ export LANG=C

$ export DEB_CFLAGS_APPEND='-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE'

$ export DEB_BUILD_OPTIONS=nocheck

$ cd root

$ git clone https://github.com/git-lfs/git-lfs.git

# 或者本站下载一份拷贝 wget https://www.mobibrw.com/wp-content/uploads/2019/11/git-lfs.zip

$ git checkout v1.2.1

$ DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -d -b -uc

可以本站下载：
golang_1.3.3-1deb8u2.dsc
golang_1.3.3-1+deb8u2.debian.tar.xz
golang_1.3.3.orig.tar.gz
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。
