Hello,

I have installed GnuRadio 3.4.0 from Git on Ubuntu, now I am trying to  
setup  
the RDS block from [https://www.cgran.org/wiki/RDS](https://www.cgran.org/wiki/RDS). I have followed the  
instructions (configure, make, make install) and apart from a missing  
italian translation file, it seemed to work (I used make -i).

However, when I use RDS blocks in GnuRadio and try to execute, I get the  
python error  
File “…/crc\_fm\_rds\_rx.py”, line 13, in   
from gnuradio import gr, rds  
ImportError: cannot import name rds

## I think I have to specify where the needed files are, I also tried to modify the PYTHONPATH, unfortunately to no avail. Does anybody have experience with this RDS package?

Hello Olek,

By default, the prefix of gr-rds install things under /usr/local. Try  
to relaunch configure with the --prefix=/usr recompile and reinstall.

By the way, I don’t think that gr-rds is compatible with Gnuradio 3.4.  
It has been successfully compiled and installed with Gnuradio 3.2.2  
and 3.3, but not for 3.4 nor the latest Git version.

Regards,

Pascal
