Resolved -- "cannot find -lhdf5_hl_cpp" compiler error with C++ code using hdf5

Symptom:

After the 1/18 system maintenance, C++ code compilation gets an error if the default hdf5/1.8.5.0 module is loaded: "/usr/bin/ld: cannot find -lhdf5_hl_cpp". 

Workaround

Users can either do any of the following module swaps and recompile: 1) module swap xt-asyncpe xt-asyncpe/5.01; or 2) module swap hdf5 hdf5/1.8.7; or 3) if the default netcdf/4.1.1.0 is loaded, then do "module swap netcdf netcdf/4.1.3".

Status

Problem is resolved by setting newer netcdf/4.1.3 and hdf5/1.8.7 to the default versions. The underlying problem has been reported to Cray.
