I installed GNU on ubuntu 12.04 lts _before_ installing UHD from  
[http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall](http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall)  
by running the following commands:

sudo apt-get -y install git-core autoconf automake libtool g++  
python-dev swig   
pkg-config libboost1.48-all-dev libfftw3-dev libcppunit-dev libgsl0-dev  
  
libusb-dev sdcc libsdl1.2-dev python-wxgtk2.8 python-numpy   
python-cheetah python-lxml doxygen python-qt4 python-qwt5-qt4 libxi-dev  
  
libqt4-opengl-dev libqwt5-qt4-dev libfontconfig1-dev libxrender-dev

git clone [gnuradio.git - GNU Radio](http://gnuradio.org/git/gnuradio.git)  
cd gnuradio  
mkdir build  
cd build  
cmake …/  
make  
make test  
sudo make install

But I didn’t find UHD blocks when I open gnu by running  
“gnuradio-companion” in terminal.  
So I installed UHD from  
[http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio\_Linux](http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Linux)  
from  
the unstable repositories.

I wanted to check if the GNU & UHD are installed or not so I ran in  
terminal :  
dell@ubuntu:~$ dpkg -l uhd  
Desired=Unknown/Install/Remove/Purge/Hold  
|  
Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend

||/ Name Version  
Description  
++±==============================-==============================-============================================================================  
rc uhd 003.007.000-1-stable Ettus  
Research - USRP Hardware Driver

dell@ubuntu:~$ dpkg -l gnuradio  
No packages found matching gnuradio.

Does this mean that UHD is installed but GNU isn’t ?!! (THIS IS MY FIRST  
QUESTION)  
But I can run GNU from terminal , how it is written that No packages  
found!!

I decided to build again GNU after installing UHD so I ran “cmake…/”  
and  
“make” commands … But the output of "cmake …/ " shows that gr-uhd is a  
disabled component!! So I won’t find UHD blocks in GNU again. What can I  
do  
? (THIS IS MY SECOND QUESTION)  
Here is the output of cmake … Hope that anyone can help me 🙂 Thanks.

Sara,

The GNURadio installation tells you at the end of that long printout  
that  
it skipped over gr-uhd, which is the block you are looking for. This  
needs  
to be installed prior to installing GNURadio, so that way GNURadio knows  
of  
it’s existence and can properly build against it. Since you installed  
the  
UHD drivers after GNURadio, you need to uninstall and re-install  
GNURadio.  
This should fix your problem.

Based on the information provided above, cd to ~/gnuradio/gnuradio/build  
and run make uninstall followed by make and then sudo make install once  
more. You need to rebuild in order to get the gr-uhd features that  
weren’t  
built during the first install. To make this go a little faster, i’d  
recommend using the -j flag with make; I generally use the number of CPU  
cores I have + 1 ( if i’m on a quad core machine, I would call ‘make -j  
5’).

I think there are a few points of confusion here. First, you said that  
you tried to build GNU Radio before installing UHD, but I’m guessing  
that was a mistake since you show here that you’ve installed UHD. If  
you build GNU Radio before installing UHD, you shouldn’t expect it to  
know about UHD.

(Also, it’s “GNU Radio” and not just “GNU” – GNU refers to the  
bigger GNU project at [www.gnu.org](http://www.gnu.org).)

When installing a project by hand like this, you are not using the  
Debian system, so there’s no reason it will be found by dpkg.

That output tells you that it didn’t find the UHD library, which could  
be for many reasons.

I would recommend trying PyBOMBS to install GNU Radio instead:
