Nvfortran/nvc problem with ISO_Fortran_binding.h

Accelerated Computing HPC Compilers nvc, nvc++ and nvfortran

i seem to always get zero values from elements of the CFI_cdesc_t struct
include <stdio.h>
include <ISO_Fortran_binding.h>
int rank_2018(CFI_cdesc_t *this){
fprintf(stderr,“version = %8.8x, rank = %d, element length = %ld\n”, this->version, this->rank, this->elem_len) ;
return this->rank ;
}
from Fortran :
interface
function rank_2018(this) result(r) BIND(C, name=‘rank_2018’)
integer, intent(IN), dimension(…) :: this
integer :: r
end function
end interface

Hi mfvalin,

Fortran 2018 C Interoperability (CFI) support is in the process of being added. Though it looks like we’re expecting this to be added in our up coming 23.9 release.
