problem of make on MAC

[hiris1228]

Hi Guys,

I cannot make on my Mac. Could you please help me?

Below is the information on my terminal when making.

Hiris-Guteki-MacBook-Pro-5:xgboost hirisgu$ make

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

Hi guys,

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

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