All,
I'm wondering if I can get theories on the best way[1] to patch HDF5
1.8.17 to build with nagfor. Namely, my build is dying when it tries to
build tf_F03.f90:
make[4]: Entering directory
`/gpfsm/dswdev/mathomp4/Baselibs/TmpBaselibs/GMAO-Baselibs-5_0_2-NAG/src/hdf5/fortran/test'
FC tf_F03.lo
NAG Fortran Compiler Release 6.0(Hibiya) Build 1064
Error: tf_F03.f90, line 128: Implicit type for SIZEOF in H5_SIZEOF_DP
Error: tf_F03.f90, line 128: Implicit type for SIZEOF in H5_SIZEOF_SP
Error: tf_F03.f90, line 128: Implicit type for SIZEOF in H5_SIZEOF_I
Error: tf_F03.f90, line 128: Implicit type for SIZEOF in H5_SIZEOF_CHR
Error: tf_F03.f90, line 128: Implicit type for SIZEOF in H5_SIZEOF_CMPD
[NAG Fortran Compiler pass 1 error termination, 5 errors]
NAG rightly complains (as NAG is wont to do) that SIZEOF does not exist
in the Fortran Standard (2003 or otherwise). There is storage_size() in
F2008 and a colleague suggested:
#ifdef NAGFOR
integer function sizeof(a)
class(*), intent(in) :: a
sizeof = storage_size(a) / 8 ! bits -> bytes
end function sizeof
#endif
and it allows it to compile.
Would this be my best bet? Or is there a better way that the HDF5 1.10
transition indicated?

[1] Note: looking at HDF5 1.10.0-patch1, the "correct" answer is
probably move to HDF5 1.10 as that seems to have revamped all the
fortran/test bits. But, I really don't want to have to deal with the
1.8=>1.10 transition at the moment. My limited testing seems to show it
might be a non-issue as I use netCDF4 only, but others use these
libraries to handle pure HDF5 files and I have not tested for side
effects everywhere. So, for now, I'm dealing with HDF5 1.8.17.
