problem of make on MAC about xgboost HOT 3 CLOSED

See the build guide, in README.md you need to remove -fopenmp flag

from xgboost.

Hi guys,

I am also getting errors on my mac with 10.9 trying out the R interface. Failed to compile.

Any help appreciated.

Try the new version on the master branch, it should be fixed by now

from xgboost.
