Not always. It's fine as long as they all increment SONAME together. I don't know if that's the case here, but if it is, I'd say the benefit of splitting is outweighed by the nuisance of increasing package count. > Second, the c++ libs were only built > with the serial libhdf5 variant, not with any of the mpi ones; Yes, that's why I specified to produce C++ libs "for all variants". > I don't know why, and am not familiar enough with hdf5 to know if > that makes any difference. I don't know why either, but I do know that it makes a difference. Regards, -Steve
