Hi Sean, Fortran C wrappers use the latest versions of the C APIs and they are hardcoded, i.e, instead of H5Dopen we use H5Dopen2 call to open a dataset. The flags you specified do not have any affect on the real function, but just on the macros like H5Dopen.
The HDF5 library versions 1.8.* have both functions H5Dopen1 and H5Dopen2 present unless —-disable-deprictated-symbols is specified when the HDF5 library is configured. By default, H5Dopen will be H5Dopen2 unless the specified compiler flags are used or the library is configure with --with-default-api-version=v16. Please see http://www.hdfgroup.org/HDF5/doc/RM/APICompatMacros.html for more details. Did you encounter any problem? Thank you!
