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, thanx, Vanessa On 09/07/2015 11:00 AM, Pierre de Buyl wrote: > Hi, > > By default, HDF5 supports several integer and real types.
