[Discuss-gnuradio] UHD Driver for USRP1 not found

[Ji Slee]

Hello,

I am a high school student who has been working with gnuradio. I have
been trying to reinstall gnuradio with UHD, but am getting the No
device error. In internet searches, I have found others who have had
the same error, but I have not found the solution to the problem.

I installed per redmine and ettus instructions below (also included prior dep.)
For UHD:

git clone git://code.ettus.com/ettus/uhd.git

cd uhd/host
mkdir build
cd build
cmake ../
make
make test
sudo make install


for gnuradio

git clone git://gnuradio.org/gnuradio
cd gnuradio
cd build
make
make test

sudo make install

sudo ldconfig


The gnuradio-companion works with dial tone example. However it cannot
find my USRP 1, giving the following error:

>linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.001-27-g93d4a16f

The uhd_find_devices command returned the following:

> linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.001-27-g93d4a16f
> No UHD Devices Found


 Finally, when I checked in ~/uhd/host/build/lib/usrp/usrp1, it was
empty. So, I am wondering if there was another step I needed to
perform to be able to use my USRP1 with the UHD.

 I really appreciate any help you can give me!

 Many thanks,
 J.
