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.

Subject: [Discuss-gnuradio] How can I build component usrp on E100?
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
$ 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
