I am using some DPDK application code that worked with DPDK 2.2.0.  I am
trying to port it to DPDK 18.08.  The code gives error:

MBUF: error setting mempool handler


I guess the app code that causes this is:

ptRxQueInfo->pool = rte_mempool_create(buf,

I really don't know how to fix this. Any suggestions please?

You should not be using 8.08 is not a Long Term Stable release. It is not supported.

You should be using rte_pktmbuf_pool_create() rather than rte_mempool_create().
Lots has changed in the years since 2.2.0

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?

May I restate my problem please as there was an error in my original
message:

I am using some DPDK application code that worked with DPDK 2.2.0. I am
trying to port it to DPDK 18.08, running on Centos 7. The code gives error:

MBUF: error setting mempool handler

This error occurs in the call to rte_pktmbuf_pool_create() below:

    for (lcore_id = 0; lcore_id < RTE_MAX_LCORE; lcore_id++) {

        if (rte_lcore_is_enabled(lcore_id) == 0)
            continue;

        iCpuSocket = rte_lcore_to_socket_id(lcore_id);

        if (iCpuSocket == SOCKET_ID_ANY)
            iCpuSocket = 0;

        // Preparing direct memory pool per Socket

        if (socket_direct_pool[iCpuSocket] == NULL)
        {
            mp = rte_pktmbuf_pool_create(   buf,
                                            NB_MBUF,
                                            32,
                                            0,
                                            RTE_MBUF_DEFAULT_BUF_SIZE,
                                            iCpuSocket);
            if (mp == NULL) {
                <print error>
                return -1;
            }
            socket_direct_pool[iCpuSocket] = mp;
        }

I don't know how to fix this. I have seen other people reporting this when
building the dpdk application code as a library (i.e. there were missing
symbols), but I am building directly as an executable.

Any suggestions please?

It looks like you are reusing this 'buf' name multiple times. At a given
time, mempool names must be unique.

About 18.08 - there was one stable release 18.08.1, but it is not an LTS
and not maintained. Strongly suggest you move to 18.11 at least, or
19.11 which has longer maintenance left.
