param num_procs[0] or proc_id[0] error!

[alandtsang]

I successfully compiled the f-stack and set FF_PATH and FF_DPDK OK. After running the example code,

./helloworld ../config.ini

and the following error occurred:

param num_procs[0] or proc_id[0] error!

I debug found getopt_long function return -1, is there any error in my usage? Thanks

static void
ff_load_arg(struct ff_config *cfg, int argc, char *const argv[])
{
    dpdk_argc_arg = 0;
    int c;
    int index = 0;
    while((c = getopt_long(argc, argv, short_options, long_options, &index)) != -1) {
        switch (c) {
            case 'c':
                cfg->dpdk.proc_mask = strdup(optarg);
                break;

Use ./start.sh -b example/helloworld -c config.ini.

OK, I see. Thank you
