原作写得比较简单，实际操作还是有很多问题，里面加了一些自已的心得（#部分）！
mldonkey是用OCmal语言写的，需要用OCmal编译器编译。由于无法交叉编译OCaml本身，所以只有在普通Linux机器上运行的MIPS虚拟机进行Ocaml和mldonkey的编译。
1. MIPS虚拟机安装
使用QEMU来虚拟MIPS系统，请在http://www.qemu.org/下载虚拟机的代码，编译安装:
./configure --prefix=/opt/qemu
make && make
# 我是在VM中的Ununtu中手工编译qemu的过程出错，无法make install。只好用Ununtu的软件包管理安装了Qemu.
#试过使用qemu manager6.0无法启动mips-qemu ,原因未明，如果xp下能行，编译会更简单些！
：
sudo apt-get install qemu-kvm-extras #安装qemu 0.11.0

下列【新】软件包将被安装：
qemu-kvm-extras
共升级了 0 个软件包，新安装了 1 个软件包，要卸载 0 个软件包，有 238 个软件未被升级。
需要下载 14.0MB 的软件包。
解压缩后会消耗掉 41.1MB 的额外空间。

正在设置 qemu-kvm-extras (0.11.0-0ubuntu6.3) ...
在下载，某大牛为我们事先做好的Debain的操作系统，这样就不用在虚拟机上安装操作系统了。
注意：下载来的镜像请使用qemu 0.10.0启动系统，我试图用{zx0}版本0.12，系统无法启动。
# 我安装的是qemu 0.11.0,{dy}次无法启动，重新安装后成功启动！

3. 编译mldonkey
在下载代码，
wget
我使用的版本是3.0.1。其实，编译本身没有什么，
解开mlonkey的压缩包，
bunzip2 -kv mldonkey-3.0.1.tar.bz2
tar xvf mldonkey-3.0.1.tar
然后进行mlonkey目录：
./configure --enable-batch
make mlnet.byte.static
由于虚拟机运行效率问题，编译进行中.................， #未完待续！。
4. 在无线路由器上运行mldonkey
请把刚编译出来的mlnet.byte.static连同虚拟机里的如下文件拷贝出来
ld.so.1, libnss_dns.so.2, libresolve.so.2 libc.so.6, libnss_files.so.2
在无线路由器上先把上述几个lib文件放置的地方加入LD_LIBRARY_PATH环境变量的。然后运行mlnet.byte.static就行了。
