Dear All: I'm on a 64-bit Fedora 23 machine with gcc/gfortran/g++ version 5.3.1-6. I'm trying to run metgrid.exe ( http://www2.mmm.ucar.edu/wrf/users/docs/user_guide_V3.8/users_guide_chap3.htm ) with GFS data. Console output shows "Successful completion of metgrid", but at the end there is "Note: The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG IEEE_DENORMAL". is this error message due to some issues with gfortran and cause metgrid.exe to behave erratically? I would like to rebuild the metgrid.exe, but how to fix these floating-point exceptions errors? please let me know if I have to add some gfortran flags while compiling the code or anything else. Thanking you, Regards, Arindam
