I believe usrp is the old driver for USRP1, which you don't need since you're running UHD. Also, the OFDM example (and the other examples) don't run on UHD yet. You can try the "next" branch from git, in which some of the examples have been ported to use UHD.

Hi, all, I have updated the kernel modules to 3.0.0 for my USRP E100. UHD is successfully built and benchmark_rx_rate in uhd/host/build/examples works. I further installed the gnuradio according to the usrpe1xx-FAQ http://code.ettus.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ $ git clone git://gnuradio.org/gnuradio.git<http://gnuradio.org/gnuradio.git> $ cd gnuradio $ ./bootstrap $ ./configure --disable-volk --disable-usrp2 --disable-usrp1 --disable-gr-video-sdl CFLAGS="-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O3" CXXFLAGS="-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O3" -with-qwt-incdir=/usr/include $ make $ make check $ su # make install # ldconfig Because the component usrp is skipped, when I try to run gnuradio-examples/python/ofdm/benchmark_ofdm_tx.py the usrp module cannot be found. ImportError: cannot import name usrp The results of configure are as follows. How can I build usrp on E100? Is that because the sdcc version is not high enough? I see this in configuration. "checking sdcc_version "2.8.0"... 2.8.0 Not building component usrp." Thanks, Yooxi ********************************************************************* The following GNU Radio components have been successfully configured: config gruel gnuradio-core gr-msdd6000 gr-audio gr-atsc gr-cvsd-vocoder gr-gsm-fr-vocoder gr-noaa gr-pager gr-radio-astronomy gr-trellis gnuradio-examples gr-uhd docs You my now run the make command to build these components. ********************************************************************* The following components were skipped either because you asked not to build them or they didn't pass configuration checks: volk gcell usrp usrp2 gr-usrp gr-usrp2 gr-gcell gr-comedi gr-gpio gr-radar-mono gr-video-sdl gr-wxgui gr-qtgui gr-sounder gr-utils grc gr-shd These components will not be built. Configured GNU Radio release v3.4.1-47-ga01c4249 for build.
