Sorry, I made a mistake. The error:

MBUF: error setting mempool handler

occurs in:

mp = rte_pktmbuf_pool_create(   buf,
                                NB_MBUF,
                                32,
                                0,
                                RTE_MBUF_DEFAULT_BUF_SIZE,
                                iCpuSocket);

Any advice please?
