notes about the install procedure for Gen2 RFID USRP (modified gnuradio library)


$ svn co -r 10532 http://gnuradio.org/svn/gnuradio/trunk gnuradio

step #1 Copy gen2_reader/gnuradio/misc_files/grc_gr_gen2_rfid.m4 to gnuradio/config

cp gen2_reader/gnuradio/misc_files/grc_gr_gen2_rfid.m4 gnuradio/config

step #2

cp -a gen2_reader/gnuradio/gr-gen2-rfid gnuradio/

step #4 line 304: GRC_GR_GEN2_RFID

This here are software dependencies from a different gnuradio project so it should contain most gnuradio dependencies : apt-get install -y libboost-dev python python2.5-dev libfftw3-dev swig sdcc-nf libusb-dev guile-1.8-dev libcppunit-dev libosip2-dev libortp7-dev asterisk

gnuradio dependencies:

  • built/installed the latest libboost

apt-get install libgsl0-dev

gnuradio build: ./configure --prefix=/usr/local/gnuradio-rfid --enable-gr-gen2-rfid --enable-gnuradio-core --enable-gr-audio-oss

make

make install

step #8 cp gen2_reader/gnuradio/misc_files/gen2_reader.rbf /usr/local/gnuradio-rfid/share/usrp/rev4


step #9 cd gnuradio/gr-gen2-rfid/src/lib

apply this patch:

gnuradio/gr-gen2-rfid/src/lib/rfid_gen2_reader.cc
