在macOS Sierra中,启用openmp的xgboost安装总是失败.
来自https://xgboost.readthedocs.io/en/latest/build.html,
我试过了:
cp make/config.mk ./config.mk; make -j4
随着,
export CC=/usr/local/Cellar/llvm/4.0.0_1/bin/clang
export CXX=/usr/local/Cellar/llvm/4.0.0_1/bin/clang++
export CXX1X=/usr/local/Cellar/llvm/4.0.0_1/bin/clang++
它失败了,
clang-4.0clang-4.0: : warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument]warning:

ld: library not found for -lomp
ld: library not found for -lomp
clang-4.0: error: linker command failed with exit code 1 (use -v to see invocation)
llvm支持openmp,但它失败了 ld: library not found for -lomp
但是,clang-omp去了boneyard,并停止了llvm的OpenMP支持.
我已经钻了,(有-v选项)
