Hi Vishwanatha,  
we already talked about this:  
[http://lists.gnu.org/archive/html/discuss-gnuradio/2015-03/threads.html#00516](http://lists.gnu.org/archive/html/discuss-gnuradio/2015-03/threads.html#00516)  
Did something change?  
Did my instructions help you or are there still problems you encountered  
and could not solve?

Best regards,  
Marcus

Vishwanatha,

the error tells you about the problem. I’ll have to rely on your ability  
to interpret that error. You might find things that you don’t  
understand, and it’s fine if you then write an email with a sufficient  
description of the problem you’re having. For now, you only give us a  
screenshot and hope that we somehow gained telepathic abilities – this  
won’t work; I’ll have to ask you to read  
[http://gnuradio.org/redmine/projects/gnuradio/wiki/ReportingErrors#Checklist-Asking-a-question-on-the-mailing-list](http://gnuradio.org/redmine/projects/gnuradio/wiki/ReportingErrors#Checklist-Asking-a-question-on-the-mailing-list)  
and follow the instructions there closely.

A very important line here is  
"…Use your judgment of how much code to include; ", because that might  
help us here (and more importantly, it might help you pin down the error  
first yourself).

Best regards,  
Marcus
