Hello G.s

I am trying to implement 802.15.4. I had taken the files from this  
website [GitHub - bastibl/gr-ieee802-15-4: IEEE 802.15.4 ZigBee Transceiver](https://github.com/bastibl/gr-ieee802-15-4).

My error was ImportError: libgnuradio-foo.so: cannot open shared object  
file: No such file or directory

I had tried sudo ldconfig too but I am receiving the same error.

I am completely new for GNU radio. So, I think you guys could help me to  
solve the problem.

Eagerly waiting for your replies

FOR MORE DETAILS:

I am using Ubuntu 14.04 and installed all the libraries required for GNU  
and successfully tested some examples using USRP.

My output was:
