Hey Marcus,  
You told me to remove previous installation and then install it from the  
source, but after installation my GRC application tool was not opening.  
Even i tried pybombs for installing Gnuradio but again same problem.  
Again after removing all the installation, i am able to find GRC  
application tool but when i click on it, it does not launch.  
Here attached is previous link,

My project is Security for cognitive radio, and now I have only 1 month  
to  
complete this. For this project i had done rigorous research, i have my  
plan of action ready, but the thing is unexpected errors in gnuradio.  
Any help will be appreciated,  
Thanks in advance,  
Abhishek.

Hi Abhishek,

can you start “gnuradio-companion” from a terminal? The things that will  
be printed there will most likely help you determine the underlying  
problem.  
If you just want something that works?, try the GNU Radio Live DVD  
image[1], which you can download, burn onto a DVD, boot from it, and  
will contain everything readily set up.

Best regards,  
Marcus
