i have updated config.mk include gcc compiler

 # choice of compiler, default use system preference.  export cc = gcc-6  export cxx = g++-6 

but seems needs me change else? not sure other changes need do. build xgboost package ./build.sh ran , installed single thread version of xgboost. failure happened when tried install jvm package. make -j4 doesn't work me suggested in documentation has issues fopenmp , gives following error

has else faced of these errors?

any appreciated. thanks! rosh

it seems need add full path gcc compiler in config file. still gave lot of warnings of not being able run open mp version not sure if multithreading version enabled. saw here: installing openmp on mac os x 10.11 if gcc installed brew require reinstall benefit of openmp. try , update answer here. current testing purpose though sufficient.
