Installing XGBoost on Mac OSX

0. Get gcc with open mp.  Just paste and execute the following command in your terminal, once Homebrew installation is completed. brew install gcc --without-multilib 1. xinpingdeMacBook-Pro:anaconda xinpingbao$ git clone --recursive https://github.com/dmlc/xgboost 2. xinpingdeMacBook-Pro:anaconda xinpingbao$ cd ./xgboost 3. Then open make/config.mk and uncomment these two lines 4. cd xgboost; cp make/minimum.mk ./config.mk; make -j4 注： 可以直接修改config.mk {1. export CC = gcc 去#，export CXX = g++ 去#, USE_OPENMP = 0 } 5. We then build with the following commands. 6. Once the build is finished, we can use XGBoost with its command line.  I am using Python, hence I performed this final step.  You may need to enter the admin password to execute it.

在Mac os下安装xgboost

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

cd xgboost; cp make/minimum.mk ./config.mk; make -j4

这是不支持多线程版本的，如果想要支持多线程，那么就要使用如下指令：

brew install gcc --without-multilib

brew相当于在Linux中的yum或者apt-get，可以到这里 下载，也可以使用如下命令：

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 

安装brew命令

然后执行命令

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

cd xgboost; cp make/config.mk ./config.mk; make -j4

有时候也会出现错误：

clang: error: : errorunsupported option '-fopenmp'  

可以参考这里 ：

首先

ls /usr/local/bin/*

找到其中的gcc g++,然后

将./config.mk中的

$ export CC=/usr/local/bin/gcc-6

$ export CC=/usr/local/bin/g++-6

之后，重新 make -j4即可。

如果是利用python调用，那么还需要

cd python-package; sudo python setup.py install

即可安装完成。
