Hi Dilip,
3.3.0 is an old version of gnuradio. The code you posted clearly contains GR
3.7 code structure;
so you're using an 3.7 gr_modtool with an 3.3.0 GNU Radio; this can't work.
Please use the gr_modtool that comes with your GNU Radio version (there was no
official gr_modtool back in the 3.3.0
days in the GR tree). It is not desirable to use such an old version of GR
unless you _really_ need to support legacy code, therefore you should try to
use GNU Radio 3.7; please install the latest versions using PyBOMBS
(http://gnuradio.org/redmine/projects/pybombs/wiki) or build-gnuradio
(http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR#Using-the-build-gnuradio-script).
Happy exploring,
Marcus Müller

Hi,
I am working with gnuradio 3.3.0 and now trying to create new block using
gr_modtool.py.
I am able to do following :
1. cmake
2. make
3. sudo make install
4. sudo ldconfig
after editing header file of bin and lib with .cc file.
Then while using newly created block with GRC I got following error
def __init__(self, *args, **kwargs): raise AttributeError("No constructor defined")
AttributeError: No constructor defined
<http://stackoverflow.com/questions/18092242/def-init-self-args-kwargs-raise-attributeerrorno-constructor-define>
Detail I have posted here
<http://stackoverflow.com/questions/18092242/def-init-self-args-kwargs-raise-attributeerrorno-constructor-define>.
Is this error due to lower version of GNURadio, if not how can I solve this.
Please help me out.
