本文档详细介绍了如何在Windows环境下使用MinGW-64完成XGBoost项目的64位构建过程，并提供了安装Python包的具体步骤。

Note that as of the most recent release the Microsoft Visual Studio instructions no longer seem to apply as this link returns a 404 error:

https://github.com/dmlc/xgboost/tree/master/windows

You can read more about the removal of the MSVC build from Tianqi Chen's comment here.

So here's what I did to finish a 64-bit build on Windows:

Download and install MinGW-64: http://sourceforge.net/projects/mingw-w64/
On the first screen of the install prompt make sure you set the Architecture to x86_64 and the Threads to win32
I installed to C:\mingw64 (to avoid spaces in the file path) so I added this to my PATH environment variable: C:\mingw64\mingw64\bin
I also noticed that the make utility that is included in bin\mingw64 is called mingw32-make so to simplify things I just renamed this to make
Open a Windows command prompt and type gcc. You should see something like "fatal error: no input file"
Next type make. You should see something like "No targets specified and no makefile found"
Type git. If you don't have git, install it and add it to your PATH.

These should be all the tools you need to build the xgboost project. To get the source code run these lines:

cd c:\
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk
make -j4

Note that I ran this part from a Cygwin shell. If you are using the Windows command prompt you should be able to change cp to copy and arrive at the same result. However, if the build fails on you for any reason I would recommend trying again using cygwin.

If the build finishes successfully, you should have a file called xgboost.exe located in the project root. To install the Python package, do the following:

cd python-package
python setup.py install

Now you should be good to go. Open up Python, and you can import the package with:

import xgboost as xgb

To test the installation, I went ahead and ran the basic_walkthrough.py file that was included in the demo/guide-python folder of the project and didn't get any errors.
