[Discuss-gnuradio] shmat issue

[Philip Balister]

I'm seeing this issue on my omap3 install with the dialtone flowgraph:

# python /usr/share/gnuradio/examples/audio/dial_tone.py


gr_vmcircbuf_createfilemapping: createfilemapping is not available 

gr_vmcircbuf_sysv_shm: shmat (3): Invalid argument 

l# python /usr/share/gnuradio/examples/audio/dial_tone.py



In both cases I can hear the dial tone fine. I'm curious why I get the 
shmat error the first time only. It looks like gnuradio falls back to 
another method of creating the shared segment. I'd like to resolve the 
shmat issue though, because I am also trying to run the kalibrate 
program and have the same shmat issue there, but it does not have a fall 
back method.

Thanks,

Philip
