Why is HDF5 giving a "too few arguments" error here?

I'm trying to compile a package which uses HDF5, which fails with:

read_hdf5_c.c:537:100: error: too few arguments to function call, expected 8, have 7
      H5Oget_info_by_idx(group_id, ".", H5_INDEX_NAME, H5_ITER_NATIVE, i, &object_info, H5P_DEFAULT);
      ~~~~~~~~~~~~~~~~~~                                                                           ^
/usr/local/include/H5Opublic.h:190:8: note: 'H5Oget_info_by_idx3' declared here
H5_DLL herr_t H5Oget_info_by_idx3(hid_t loc_id, const char *group_name,
       ^

The definition of H5Oget_info_by_idx3 in H50public.h is

H5_DLL herr_t H5Oget_info_by_idx3(hid_t loc_id, const char *group_name,
    H5_index_t idx_type, H5_iter_order_t order, hsize_t n, H5O_info2_t *oinfo,
    unsigned fields, hid_t lapl_id);

which indeed has 8 arguments. The calling code is only passing 7, and also there are only 7 parameters listed in the official docs:

https://support.hdfgroup.org/HDF5/doc/RM/RM_H5O.html#Object-GetInfoByIdx

The missing one is unsigned fields.

Could my installation of the hdf5 dev library outdated? Was this 8th parameter removed?

I'm running hdf5 1.12.0

It seems that as of hdf5 1.12.0 the interface changed a little (see the changelog) when they introduced H5Oget_info_by_idx3 and the API documentation lags behind.

I could get it to compile (and more importantly also run) in a project of mine by setting the fields to H5O_INFO_BASIC. In case some fields which are required for you are not contained in the object info struct there is also H5O_INFO_ALL which might do the trick.
