Hi,
At about line 30 in file netcdf4_constants.f90, the following code:
integer (kind = EightByteInt), parameter, public :: &
nf90_fill_uint = 4294967295_8
should be changed to read:
integer (kind = EightByteInt), parameter, public :: &
nf90_fill_uint = 4294967295_EightByteInt
This is needed because the NAG compiler does not, by default, use the
typical practice of using byte counts for kinds. An 8-byte integer
actually has a kind of 4. (Kinds are 1, 2, 3, and 4 for one-byte,
two-byte, four-byte, and eight-byte integers. Kind=8 is not accepted.)
NAG does have a -kind=byte compilation option. But use of this option introduces further problems. Namely that all Fortran code that USEs a module compiled in this mode must also be compiled the same way. Which is a pain for large programs that use libraries from multiple sources.
I checked the netcdf-fortran-4.4-beta1 tarball, and the bug is not fixed. The same code appears in file netcdf_constants.f90 at around line 152.
