Hi,I am trying to install gnuradio on Kubuntu 14.04 64 bit. I am using the binaries from the main Ubuntu software repository to install the same by running the following: sudo apt-get install gnuradioThe installation works fine. However, when I tried running gnuradio-companion, I got the GUI indicating the following:Cannot import gnuradio.Is the python path environment variable set correctly? All OS: PYTHONPATHI felt that this could be due to the fact that I have Anaconda’s Python [https://store.continuum.io/cshop/anaconda/](https://store.continuum.io/cshop/anaconda/) installed, which I do so for several reasons. So, my Python runs from /home/nipun/anaconda/bin as opposed to the default Ubuntu path. I verified this by importing gnuradio from Python run by /usr/bin/python as opposed to Anaconda’s python (/home/nipun/anaconda/bin/python). I could import gnuradio from /usr/bin/python.This suggests that gnuradio picks up the default Ubuntu python location. I then uninstalled gnuradio using sudo apt-get remove gnuradio and set my PATHS as in .bashrc, did a sudo ldconfig and source .bashrc. My paths at this point were as follows:nipun@nipun-batra:~$ echo $LD\_LIBRARY\_PATH /usr/lib32:/home/nipun/anaconda/bin:/usr/local/libnipun@nipun-batra:~$ echo $PYTHONPATH /home/nipun/anaconda/bin:However, even after this point, gnuradio would work from default Ubuntu path only. Also, gnuradio-companion would naturally complain and not startup.Question 1: How can we set custom Python path for gnuradio to install to?Question 2: Anaconda has made life much easier for the scientific Python community. It makes installing on Windows, Mac and Linux pretty easy. Also, dependencies such as numpy, scipy, etc. are also taken care of. Would the gnuradio team consider putting up a package on Anaconda. The Anaconda team look pretty helpful and should be willing to help. I think that this can save a lot of questions on installation related questions across different environments. ---

As stated on [http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio\_Linux](http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Linux) the installation of gnuradio will not necessarily install all dependencies. They recommend to run sudo apt-get install python python-wxgtk2.8 pyqt4-dev-tools python-qwt5-qt4 python-numpy libboost-all-dev libusb-1.0.0-dev I would also recommend to install the GNU Radio with Ettus repositories instead of the ones of Ubuntu. 2014-08-31 16:02 GMT-06:00 nipun [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---

You can set Python-specific CMake vars to your locations, e.g. PYTHON\_INCLUDE\_DIR and PYTHON\_LIBRARY. M ---

Thanks for your reply. However, this does not solve the problem, which I suppose may involve compiling the package and passing in the appropriate Python locations maybe? On Sun, Aug 31, 2014 at 7:00 PM, haroldmk [via GnuRadio] \< ---

The clue is in the bits that say FALSE in the output: Configuring gnuradio-companion support… – Dependency ENABLE\_GNURADIO\_RUNTIME = ON – Dependency ENABLE\_PYTHON = ON – Dependency PYTHON\_MIN\_VER\_FOUND = TRUE – Dependency CHEETAH\_FOUND = TRUE – Dependency LXML\_FOUND = TRUE – Dependency PYGTK\_FOUND = FALSE – Dependency NUMPY\_FOUND = TRUE – Disabling gnuradio-companion support. – Override with -DENABLE\_GRC=ON/OFF – Configuring gr-qtgui support… – Dependency Boost\_FOUND = 1 – Dependency QT4\_FOUND = FALSE – Dependency QWT\_FOUND = FALSE – Dependency ENABLE\_VOLK = ON – Dependency ENABLE\_GNURADIO\_RUNTIME = ON – Dependency ENABLE\_GR\_FFT = ON – Dependency ENABLE\_GR\_FILTER = ON – Dependency PYTHONLIBS\_FOUND = TRUE – Dependency PYQT4\_FOUND = TRUE – Disabling gr-qtgui support. – Override with -DENABLE\_GR\_QTGUI=ON/OFF Therefore you need to install pygtk, qt4 and qwt. Just search using ‘synaptic’. Mike – Mike J. M0MIK BSc MIET Email: removed\_email\_address@domain.invalid Web: [http://scanoo.com](http://scanoo.com) ---

Hi, Thanks. I did this and am almost able to get everything working. Following is the command I am invoking: nipun@nipun-batra:~/git/gnuradio/build$ cmake -DPYTHON\_EXECUTABLE=/home/nipun/anaconda/bin/python2.7 -DPYTHON\_INCLUDE\_DIR=/home/nipun/anaconda/include/ -DPYTHON\_LIBRARY=/home/nipun/anaconda/lib/libpython2.7.so -DCMAKE\_INSTALL\_PREFIX=/usr ../ Everything seems ok. But, gnuradio-companion and gr-qtqui end up in disabled components. I have attached the entire log file. Would appreciate if I am helped to figure how to have 0 disabled components.
