I try to ported a fortran code to GPU using openacc likes
!$acc parallel loop do i = 1,n CB = CBC(i,1) if (CB .eq.'V ') then ....
but got compiling error
PGF90-S-0155-Call to PGI runtime function not supported - pgf90_str_copy_klen
where CBC is a character array. Does pgi compiler not support character array in acc parallel loop? Should I have to change the character to integer array?
