Hi, By default, HDF5 supports several integer and real types. Is there any reason it should not find the appropriate type?
What cannot be done, I guess, is request "H5T_NATIVE_INTEGER" or "H5T_NATIVE_DOUBLE" if the option "-fdefault-real-8" is given. Then, one must pick the datatype depending on the combination of library, compile options, etc. Another possible issue is the integer type of the variable "error" (or for that matter, the dimensions, etc) that also come into play.
