Hey guys,
I was wondering if the whole hier_block2 thing was working yet. I tried to
run the blks2.synthesis_filterbank in a manner that seemed appropriate and
got the following error:
terminate called after throwing an instance of 'std::runtime_error'
what(): streams_to_stream(5): insuffici
You need to understand the basics of compiling and linking. Otherwise
you're going to keep taking blind shots in the dark that won't work.
You could spend an hour learning and understanding it, or hours on top
of hours guessing and waiting for others to attempt to fix things for
you which
By the way, when I defined divcom_shared_func.cc in only ONE of the
files, the other files won't compile successfully complaining that
some functions are NOT yet defined.
And so I'm forced to define divcom_shared_func.cc in all the other
files. Doing this results in my original problem... So what
I still have the same problem. Actually, I am just including header
files of my own design. And as par your suggesstion, I decided to
include them in a file called divcom_shared_func.cc.
In short divcom_shared_func.cc contains only the following lines that
are needed by my other signal processing
Thanks!
I'll try this.

It's possible that your sound card is being used by another application.
For example, firefox or audacious is using the card. Make sure you're
in the sound group and have permission to the device also.

Hi,
I got a python class that contains a gr.message_source as in the
following. When UDP packets came in "enqueue_pkt" was called. Packets
were converted into stream and inserted into a gr.msg_queue. Now I tried
to dump the stream to an audio device by connecting the message_source

Hi,
Does anyone know of good places to look for jobs in SDR?
Does anyone work for a company that is looking for a programmer with experience
in SDR and/or gnuradio?
Thanks,

In short, could I change the g++ compilation rules? How do I do this?

I have a question.
I am trying to make 4 signal processing blocks wherein some of the
definitions for its computations will be REPEATEDLY defined. I really intend
this. However, basing from the gr-howto module (of which I used the built-in
dependencies there), the compiler ALWAYS COMPLAINS of a mu

Just a few quick questions, i do a -v on

does it means that 16 complex samples represent the
