Hi Crespi, You have neglected to tell us virtually anything about your problem. Could you please tell us: which version of GNU Radio? trunk, tarball (which one), etc? what operating system, distribution and architecture? the command line you issued any modifications you may have made to distributed code? anything else that might be relevant Thanks, Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
