How can I build component usrp on E100?

GNU Radio
1

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-FAQhttp://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,

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.

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.
