the libxgboost4j.so exists in the folder of /lib in xgboost4j-0.7.jar

@gypsysunny Did you ever figure out this problem? I'm running into something very similar (but with /lib64/libm.so.6 rather than libgomp.so.1.

To the xgboost developers: it seems like a libxgboost4j*.so is getting built during a run, but then running something that requires this library is done in a different environment?

I have the very same error. Someone in a related post mentioned installing gcc on the spark nodes. I had no chance tho to try that til tomorrow.

See #1033 for further reference.

My libxgboost4j.so is contained in the lib folder in xgboost4j-07.jar tho.

XGBoost has dependency on libgomp1, which is OpenMP runtime for GCC. You should install libgomp1
