This isn't an error, and you should see this only the first time you attempt to run any GR application as a particular user on a given machine. (Unless for some reason, you can't write into ~/.gnuradio/prefs/gr_vmcircbuf_default_factory.) gr_vmcircbuf_createfilemapping is only available under Windows. FWIW, on most Linux systems, it ends up getting set to gr_vmcircbuf_sysv_shm_factory Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
