Hi,
In order to look for correct usage of gr::io_signature::makev,
I checked this example
https://github.com/gnuradio/gnuradio/blob/master/gr-digital/lib/fll_band_edge_cc_impl.cc
and found
static int ios[] = {sizeof(gr_complex), sizeof(gr_complex),
sizeof(gr_complex), sizeof(float)};
static std::vector<int> iosig(ios,
ios+sizeof(ios)/sizeof(int));
and then use as io_signature::makev(1, 4, iosig))
Basically I have to use it in sync_short.cc from gr-ieee 80211 in
order to create more inputs.
But if I use the above two lines inside the class i.e.
sync_short_impl, I get lots of error. I have attached the file for
reference. Could you please suggest me correct usage. I can give
more information if needed.
