Re: [Discuss-gnuradio] Using the GRUEL msg_queue

[Tommy Tracy II]

More information on this.

I checked the build directory to see if the gruel/msg_queue had built.

cd ~/src/gnuradio/build/gruel/src/lib/msg

ls

**nothing**

I then GREPd my python/gruel directory and couldn't find any msg_queue either.

This leads me to believe that gruel/msg_queue wasnt installed.

I tried to build gruel:

cd ~/src/gnuradio/gruel/build

cmake ../

Is there something missing from my build, or is this a bug?

Dear GNU Radio,

I am looking to use the GRUEL msg_queue for passing messages (of PMT type) from block to block in python.

I can use the old gr.msg_queue as shown below:

from gnuradio import gr

message_queue = gr.msg_queue(<max size>)

How would I use a GRUEL message queue? Anyone have any documentation on this?
