I did a lot of testing and encountered multiple problems.
1) my other computer has ZC and seems to be working, and it print out is
license 6.1.1.150917. the computer which is not working having license 6.0.x.
2) so I try to install 6.1.1 on it. I copy the same library over and get the
libnuma error at .userland/lib/configure.
NOTE: In fact I had libnuma-dev installed.
ii libnuma-dbg 2.0.8~rc3-1
Debug package for libnuma
ii libnuma-dev 2.0.8~rc3-1
Development files for libnuma
ii libnuma1 2.0.8~rc3-1
Libraries for controlling NUMA policy
ii numactl 2.0.8~rc3-1

Please install libnuma-dev in order to use PF_RING
3) and than I tried the new dev download from https://github.com/ntop/PF_RING
and i get this:

4) the funny thing is the other computer which installed 6.1.1 can compile this
new pf_ring version, and they have exactly the same version of ubuntu (Ubuntu
12.04.5 LTS), and gcc (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ).

Hi Brianit does work for me with the same configuration
# ethtool -i eth0
driver: e1000e
version: 3.2.4.2-NAPI
..
# ./zbalance_ipc -i zc:eth0 -c 1 -n 1
max_packet_len=1536

Please print:1. asio::pf_ring::max_packet_len(device_name.c_str())2.
buffers[0]->len before pfring_zc_send_pkt()

Subject: [Ntop-misc] Failed to send packet total size greater than 64bytes

pfring_zc_send_pkt() always return -1 when the message size (include the header
+ my application data) is greater than 64 bytes. Please help.
This is how I create the cluster
zc = pfring_zc_create_cluster(cluster_id,
asio::pf_ring::max_packet_len(device_name.c_str()), 0, NBUFF,
numa_node_of_cpu(bind_cpu), NULL /* auto hugetlb mountpoint */
);
if (zc == NULL)
{
fprintf(stderr, "pfring_zc_create_cluster error [%s] Please check
your hugetlb configuration\n", strerror(errno));
return -1;
}
zq = pfring_zc_open_device(zc, device_name.c_str(), tx_only, 0);
if (zq == NULL)
{
fprintf(stderr, "pfring_zc_open_device error [%s] Please check that
%s is up and not already used\n", strerror(errno),
device_name.c_str());
return -1;
}
fprintf(stderr, "Sending packets to %s\n", device_name.c_str());
for (int i = 0; i < NBUFF; i++)
{
buffers[i] = pfring_zc_get_packet_handle(zc);
if (buffers[i] == NULL)
{
fprintf(stderr, "pfring_zc_get_packet_handle error\n");
return -1;
}
}
This is how I send the packet
char a[23] = {0}; //23 + 42 = 65 return -1 from the send function,
resetting a to 22 it works
int tot_msg_size = forge_udp_packet(pfring_zc_pkt_buff_data(buffers[0],
zq), 1600, a, sizeof(a), parse_ip_v4_string(sender_ip.c_str()),
sender_port, parse_ip_v4_string(mcast_ip.c_str()),
mcast_port);
std::cout << "tot_msg_size:" << std::dec << tot_msg_size << std::endl;
buffers[0]->len = tot_msg_size;
std::cout << "buffers[0] : ";
for (int i = 0; i < buffers[0]->len; ++i)
{
std::cout << std::hex << (int) pfring_zc_pkt_buff_data(buffers[0],
zq)[i] << " ";
}
int rc = pfring_zc_send_pkt(zq, &buffers[0], 0);
