Installation de Xgboost sur Mac

Question

J'essaye d'installer xgboost sur mon mac (10.12.5) et après plusieurs tentatives je n'ai pas réussi. Je suis différent tuto essayant de modifier gcc variable en ajoutant gcc-6 mais j'ai le même problème.

Alors ce que je faisais:

1. clone git --recursive https://github.com/dmlc/xgboost
2. cd xgboost; cp make/minimum.mk ./config.mk; faire -j4

Je l'erreur suivante:

/usr/local/bin/g++ -std=c++11 -Wall -Wno-unknown-pragmas -Iinclude -Idmlc-core/include -Irabit/include -I/include -O3 -funroll-loops -msse2 -fPIC -DDISABLE_OPENMP -MM -MT build/learner.o src/learner.cc >build/learner.d

Ma version gcc est:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 
Apple LLVM version 8.1.0 (clang-802.0.42) 
Target: x86_64-apple-darwin16.6.0 
Thread model: posix 
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin 

je vraiment besoin de votre aide. Pour le moment j'utilise pip install xgboost pour utiliser la librairie mais je sais que ce n'est pas la bonne façon d'utiliser cette librairie. Merci pour votre aide

ps: désolé si mon anglais est pas correct, je ne suis pas couramment
