When I'm compiling it on a cluster with ifort by using -r8 flag for real*8, then there is no problem with the so called "H5T_NATIVE_DOUBLE", i guess, building the library with the -fdeafault-real-8 flag on my own computer it whats's causing the problem, The issue is compilers/systems have different behaviors for handling promotion of reals; some will not promote real*8 to real*16 and some will. It might be the case that your system does not have real*16? Which version of gcc and what system/OS are you using? We’ve change the behavior in v1.10.0 release so that we create an interface for all valid KINDs of both REALs and INTEGERs. That way you should never have an interface that does not have a matching valid KIND associated with it.

What cannot be done, I guess, is request "H5T_NATIVE_INTEGER" or "H5T_NATIVE_DOUBLE" if the option "-fdefault-real-8" is given. Then, one must pick the datatype depending on the combination of library, compile options, etc. Another possible issue is the integer type of the variable "error" (or for that matter, the dimensions, etc) that also come into play.

The problem is the native double in HDF5 does not match the native double in your program because you promoted real to double precision in your program but not in the HDF5 library. Try building the HDF5 library with FCFLAGS =-fdefault-real-8. You might also want to look at the example h5ex_d_rdwr_kind_F03.f90 at https://www.hdfgroup.org/HDF5/examples/api18-fortran.html , which uses the newer F2003 APIs. This example shows you how to automatically determine the correct data type for a given REAL. This is important for robustness if you are going to be changing the size of REALs with compiler flags.
