Re: gnuradio 3.8 errors with gr_modtool

Thank you all for your comments.

I re-installed Ubuntu, thinking that it was a problem with  my installation, but I get the same errors again.

Marcus, I re-installed git, but I get the same error.

I have no idea what is happening. I followed this steps

1 - Installed fresh Ubuntu 18.04.4 LTS

2- Installed git, cmake, swig, gnuradio.

To install gnuradio, I used:

  $ sudo add-apt-repository ppa:gnuradio/gnuradio-releases
   $ sudo apt-get update
   $ sudo apt-get install gnuradio

3. Then when I use gr_modtool, I get the errors I reported in the first message.

Any help would be greatly appreciate it, thanks!

The problem comes from Python byte-compiled files used as templates.

Perhaps the template processor is choking on a .pyc file?

The solution is to remove all .pyc files found under
/usr/share/gnuradio/modtool/gr-newmod
(or whatever the correct path is for the modtool template directory
in your installation.)

If you have files like
.../gnuradio/modtool/gr-newmod/python/build_utils_codes.pyc
.../gnuradio/modtool/gr-newmod/python/build_utils.pyc
.../gnuradio/modtool/gr-newmod/python/__init__.pyc

then this is likely the trouble.

In Debian, this bug is #946120
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946120

It has been fixed in Debian's gnuradio 3.8 packages, so I am curious
about how you might have ended up with this trouble.

Hope that helps,
-Maitland
