Hi,
I have made a block with take two streams of input and produces four
stream of outputs.
The*impl.cc* file has the following declaration:
static int ios1[] = {48, 48*sizeof(float), 48, 48*sizeof(float)};
static std::vector<int> iosig1(ios1, ios1+sizeof(ios1)/sizeof(int));
soft_frame_equalizer_impl_dc::soft_frame_equalizer_impl_dc(Equalizer_soft_dc
algo, double freq, double bw, int scaling, int threshold, bool log, bool
debug) :
gr::block("soft_frame_equalizer_dc",
gr::io_signature::make2(2, 2, 64 * sizeof(gr_complex), 64 *
sizeof(gr_complex)),
gr::io_signature::makev(4, 4, iosig1)),
I made the corresponding xml file also. No error during compiling but
when I connect my block and run I get the error:
File
"/home/john/myprefix/src/gr-ieee-80211/examples/sbmrc_testing.py", line
555, in <module>

return _runtime_swig.top_block_sptr_primitive_connect(self, *args)
*ValueError: port number 1 exceeds max of 0*
I am attaching the xml file. Can anyone help me figuring out the mistake :)
