1. 下载安装 git-windows 和 mingw32-make, g++(64位)
   https://github.com/git-for-windows/git/releases/download/v2.7.3.windows.1/Git-2.7.3-64-bit.exe
   http://mirrors.aliyun.com/CRAN/bin/windows/Rtools/Rtools33.exe
   注意 windows 10 64位系统，用tdm-gcc编译后，出现动态链接库错误。 最新的mingw可以解决，下载见这里x86_64-5.3.0-release-win32-seh-rt_v4-rev0.7z

2. 打开git bash， 输入下面命令

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost

git submodule init
git submodule update

alias make='mingw32-make'
cp make/mingw64.mk config.mk; make -j4

cd python-package/
python setup.py   install
