Basic UHD installation question

Thank you for reading this.

I’ve finally been able to successfully compile gnuradio after spending
almost the entire day on it. There are still a few disabled components
but I’ll look into those later. Now I’m trying to compile UHD so that I
can use an Ezcap Ez TV dongle. I understand that I have to install UHD
before installing gnuradio.

What I’ve done is make a build directory under gr-uhd as follows:

/usr/local/src/gnuradio-3.6.0/gr-uhd/build

and then run cmake …/

This is the result:

– The C compiler identification is GNU
– The CXX compiler identification is GNU
– Check for working C compiler: /usr/bin/gcc
– Check for working C compiler: /usr/bin/gcc – works
– Detecting C compiler ABI info
– Detecting C compiler ABI info - done
– Check for working CXX compiler: /usr/bin/c++
– Check for working CXX compiler: /usr/bin/c++ – works
– Detecting CXX compiler ABI info
– Detecting CXX compiler ABI info - done

Could not find module FindUHD.cmake or a configuration file for

UHD.

Adjust CMAKE_MODULE_PATH to find FindUHD.cmake or set UHD_DIR to the
directory containing a CMake configuration file for UHD. The file
will
have one of the following names:

 UHDConfig.cmake
 uhd-config.cmake

CMake Error at CMakeLists.txt:30 (include):

Unknown CMake command “GR_REGISTER_COMPONENT”.

CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as

 cmake_minimum_required(VERSION 2.8)

should be added at the top of the file. The version specified may be
lower
if you wish to support older CMake versions for this project. For
more
information run “cmake --help-policy CMP0000”.
This warning is for project developers. Use -Wno-dev to suppress it.

I think you’re a bit confused. You need to install the UHD library.
The gr-uhd directory you’re in here is the GNU Radio wrapper for GNU
Radio. Go here for the UHD library:
http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki

Then, you have to build GNU Radio, running cmake to find libuhd. This
will enable gr-uhd. There are build instructions in the manual that
might help:

Marcus, I tried the build-gnuradio script but I ran into all sorts of
problems. It was far quicker and easier to download the gnuradio tar
file and compile it.

More than just a bit, at the moment Tom, and thanks for the links.

It’s designed for Ubuntu and Fedora and Debian Squeeze. Running it on
anything else is a crap-shoot.
