我遇到此错误：（1）中的函数“ parallel_irecv_cv”没有任何隐式类型

Question

我正在尝试在gcc版本7.4.0（Ubuntu 7.4.0-1ubuntu1〜18.04.1）的系统上编译软件

do i = 1, aztec_obj%data_org(AZ_N_neigh+1)
          proc = aztec_obj%data_org(AZ_neighbors+(i-1)+1)
          !  Receive from processor i in the list
          len = aztec_obj%data_org(AZ_rec_length+(i-1)+1)
          ! len from dataorg includes neq vector entries per external element
          ! therefore, len should be adjusted to mean noel element per ext.
          len = (len*noel)/aztec_obj%neq
          numcom = numcom + 1
          req(numcom) = parallel_irecv_cv(data(recvstart), len*8, proc, tag+myid)
          recvstart = recvstart + len
          ! Send to processor i in the list
          len = aztec_obj%data_org(AZ_send_length+(i-1)+1)
          call c9pack(data, aztec_obj%data_org(sendstart),len,work(iw),aztec_obj%neq,noel)
          numcom = numcom + 1
          len = (len*noel)/aztec_obj%neq
          req(numcom) = parallel_isend_cv(work(iw), len*8, proc, tag+proc)
          iw = iw + len
          sendstart = sendstart + aztec_obj%data_org(AZ_send_length+(i-1)+1)
       end do
