error happens when install xgboost4.0 in windows7, python2.7

问题

Here is the process I tried to install xgboost:

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

It was good until I ran the code in my git bash

 make -j4

It goes wrong:

I find some reference which shows the reason may be related to the difference between the windows system and Unix, but it is beyond my konwledge.

I installed mingw64

回答1:

There was an issue raised on the github page.

After cloning, checkout to version 9a48a40 then repeat the steps you performed above. I was having the same issue, and this worked for me.

Quoting from the link:

Fixed, just clone repo and then checkout to 9a48a40 until they fix it, something in the last commits must have screwed up the compilation:
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git checkout 9a48a40
git submodule init
git submodule update
