Hmm: I have a working program which has a USRP perform TX & RX on the one radio, using transmit_path & receive_path. With two USRPs I can do RTS/CTS and transmit a packet with ACK. My receive_path was not picking up its own transmit_path's packet transmissions erroneously. This was even though

I found out that AC_PROG_MKDIR_P is defined only on autoconf 2.60, while gnuradio requires only autoconf 2.57 and above. After a google search, I found this patch: # AC_PROG_MKDIR_P # is a backport of autoconf-2.60's AC_PROG_MKDIR_P. # Remove this macro when we can assume autoconf >= 2.60. m4_i
