Make Errors with Out of Tree Block

GNU Radio

I have an energy detector block and I am trying to gr_message with it:

void energy_detector_sink_f_impl::send_to_message_q(float *buffer,

int
buffersz) {
gr_message_sprt msg = gr_make_message(0, sizeof(float),
buffersz,
sizeof(float)*buffersz);
memcpy(msg->msg(), buffer, sizeof(float) * buffersz);
d_msgq->insert_tail(msg);
}

and I get this error when I run the “make” command

/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_q(float*,

What am I doing wrong here? I thought msg is getting declared with
gr_message_sptr msg =

Thanks

Jon

PS I attached the C++ code to be through.

Maybe a sign to move away from message queues? :smiley:

In any case, you have a typo in the code. Fix it and your errors should
go away.

Share pointer abbreviation: S-P-T-R not S-P-R-T.

Thanks for the pointer about typos Martin.
