I'm updating older code from using the old streaming messaging to the new and improved message passing and PMTs. However I am getting an error compiling.
Here is the code snippet:
void energy_detector_sink_f_impl::send_to_message_p(float *out, int items_consumed) {
pmt::pmt_t msg = pmt::cons(
const pmt::pmt_t out,
const pmt::pmt_t sizeof(float)*items_consumed
);
message_port_pub(d_outfreq, msg);
}
and the error:
/home/fox/git_repos/custom_modules/gr-specsense/lib/energy_detector_sink_f_impl.cc: In member function ‘void gr::specsense::energy_detector_sink_f_impl::send_to_message_p(float*, int)’:

By no means do I consider myself an expert in C++ so I am not really sure if this is a PMT problem or not but because PMTs are involved it makes troubleshooting via Google a little trickier.
