Hi,
Perhaps you haven't installed UHD properly. Here are the instructions
for building it correctly on Ubuntu-11.04.
Step 01.00: Download the UHD sources from the Ettus research git repository.
$ mkdir ettus
$ cd ettus
$ git clone git://ettus.sourcerepo.com/ettus/uhd.git
Step 01.01: Build the UHD driver.
$ cd uhd/host
$ mkdir build
$ cd build
$ ccmake ../
This will bring up the text-based GUI configuration utility.
Press g twice to accept defaults and generate the makefile
$ make -j 6
$ make test
$ sudo make install
Step 01.02: Modify your .bashrc file to ensure that libuhd.so is in your
LD_LIBRARY_PATH:
export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
Step 02.00: Checkout the latest GNU Radio sources from the git repository.
$ git clone http://gnuradio.org/git/gnuradio.git
Step 02.01: Configure and build GNU Radio.
$ cd gnuradio
$ ./bootstrap
$ ./configure
$ make -j 6
$ make check
$ sudo make install
To clean the GNU Radio build, type the following command:
$ make distclean
Step 02.02: Modify your .bashrc file and .gnomerc file to update the PYTHONPATH
as follows:
export
PYTHONPATH="/usr/local/lib/python2.6/dist-packages:/usr/local/lib/python2.6/site-packages:$PYTHONPATH"
