You can override it in the ~/.gnuradio/prefs/vmcircbuf_default_factory file. Just put in there the line (with no newline): gr::vmcircbuf_createfilemapping_factory And that will tell the system to use that method of managing the circular buffers. Though it's supposed to test to see if your system can handle the shared memory method first before setting this prefs file. So I guess there's something different on the ARM that's not being tested for compliance here. -- Tom Visit us at GRCon13 Oct. 1 - 4 http://www.trondeau.com/grcon13 _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
