then try run dpdk test, it's OK












then run the example:





I think the configuration is ok,   it is "dpdk-helloworld" binary.

Hi,

Most likely PCI bus driver (a DPDK library) is missing.
Either it is not linked into "helloworld" if it is your own app;
or the path to DPDK libraries (*.so) is not in LD_LIBARY_PATH
if it is "dpdk-helloworld" binary.

If this doesn't help, please post exact commands and their full output (log),
not just "success" or "is right".
