ALLOCATE(data_out(data_dims(1)))

Data set I'm trying to read looks like this:
HDF5 "GMODO_npp_d20100906_t2110510.h5" {
DATASET "/All_Data/VIIRS-MOD-GEO_All/MidTime" {
DATATYPE H5T_STD_I64BE
DATASPACE SIMPLE { ( 48 ) / ( H5S_UNLIMITED ) }
DATA {
(0): 1662498685374717, 1662498687161083, 1662498688947446,
(3): 1662498690733806, 1662498692520176, 1662498694306565,
...

I think the problem I have is a data type. I also tried to read as =>
CALL h5dread_f(dset_id,H5T_NATIVE_INTEGER,data_out,dims,error)
(I know it supports only 32-bit, but I didn't find anything for 64-bit.)
The result is always the same it gives me some weird numbers.
What data type should I use in Fortran 90?
int8 = selected_int_kind(8) (i.e int range 10^8) will not be big enough to hold the numbers you are trying to read, try selected_int_kind(15) which should give you an 8 byte integer.

Thank you. You're right, int8 isn't enough. I tried to use int15 and int18.
It gives me the following compiling error (both gfortran and ifortran).

You will have to compile hdf5 so that 8 byte integers are the default integer type ( FCFLAGS = : -i8 with intel, fdefault-integer-8 with gfortran). In the next release this requirement will be removed and, additionally, you will be able to associated the KIND type with the hdf5 type.

The hdf5 integer default type already has being set as 8 byte.
I also thought that a problem might be that a data set is big endian,
and set a compiler's environment to that. Anyway it gives me the same error.
Do you have any other ideas?
Thanks,
Denis

If it can not find the subroutine interface for h5dread_f then that has nothing to do with the data; it's not finding the correct interface for h5dread_f because the arguments do match the available interfaces. The signature for h5dread_f is
Notice if you pass an 8 byte integer, but the library has default 4 byte integers then it will not find the correct interface.

Sorry, I might didn't explain a problem clearly. Here it is.
The data I'm trying to read with f90 is 64-bit integer array. By default in f90 integer is 4-byte.
As soon as I declare data_out array as (kind=8) the call statement starts to cause an error while compiling (see below).
When I changed data_out to (kind=4) it compiles and reads the data OK (I checked on the other data set).
Here is a part of code.
! read data set
CALL h5dread_f(dset_id,nat_type_id,data_out,data_dims,error)
-----
Here is an error when I declare 8 byte integer.

By default, in the hdf5 libraries, integer is set as 8-byte.
Any ideas?
