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

[xi yang]

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
