You probably looked at the C function for H5LTset_attribute_int and
found "hsize_t size". The types usually match between Fortran and C and
actually there is a mistake in the C documentation and "size" should be
of type size_t and not hsize_t, we'll fix it in the documentation.

Thanks, this was very helpful. I suppose I mis-read the documentation
or code at this point.
Cheers

Hello everyone.
My fortran code using hdf5 compiles nicely on a number of
machines.
After losing my laptop (sad, but true) I am now installing
hdf5 (and
other stuff) on my machine to be able to compile my code
again.
Needless to say, I have made no changes to my code, so
compilation
should be a breeze after installing all dependencies.
However, I get a number of errors of this kind (one per
subroutine
call, I am doing several):
/home/paulanto/Code/Rayleigh2D/Rayleigh2D_Modules/R_save.f90:121.29:
(/ i_surface /), int(1, kind=hsize_t),
hdferr)
1
Error: Type mismatch in argument 'size' at (1); passed
INTEGER(8) to
INTEGER(4)
The relevant subroutine call looks like this:
call h5ltset_attribute_int_f(file_id, root,
n_surfaces_name, &
(/ i_surface /), int(1, kind=hsize_t),
hdferr)
h5ltset_attribute_int_f (and probably the other functions) is
expecting "size" to be size_t, not hsize_t.
hsize_t and size_t will only be the same depending on the OS ,
compiler flags, etc../
Changing hsize_t to size_t should fix the problem(s).
I had the same issue when changing compilers (between ifort and
gfortran) that I resolved thanks to your help.

My preliminary conclusion is that hsize_t is somehow not the
type
that the hdf5 subroutine is expecting. Probably it coincides
with the
correct type on some CPUs or some operating systems, hence it
has
worked until now.
My hdf5 library (1.8.7) and my code are both compiled with
gfortran
4.6.1, which I have used with success before. One potential
difference
is that this PC (which I'm borrowing) is running 32 bit linux.
Is the
error in my code, is there a bug in hdf5, does gfortran handle
this
incorrectly, or something else?
Thanks in advance,
Paul
