GRC: 'Utils' not defined

GNU Radio
1

G’day,

Its been a while since I last used GRC and a lot has changed since then.
I’ve
built and installed GNU-Radio after merging GRC. I can run the sample
and
also create new circuits, but when load older GRC files I’m getting the
following error:

Loading: “/home/wulf/dsp/ssb.grc.xml”
Parser Error: global name ‘Utils’ is not defined

Failue

I can’t find any reference to ‘Utils’ in any of these files and failed
to find
any reference to a possible solution using Google. Can someone push me
in the
right direction?

Many thanks in advance,

cheerio Berndt

It’s not my area of expertise, but the Utils class is defined in
init.py here:

http://gnuradio.org/trac/browser/gnuradio/trunk/grc/src/utils

There is also a convert.py utility which supposedly converts old GRC
flowgraphs to the new format. I remember Josh saying something about
needing a conversion, but that conversion was possible.

As I said, I am no expert in GRC and Josh is obviously the authority -
but good luck with your older GRC files.

There is a conversion script that is supposed to automatically convert
older grc.xml files. Anyway, when I was reorganizing grc I forgot to
update an import statement in the converter.

Its fixed now.

G’day Josh,

thanks, this fixed the problem. I can now load and convert the old
applications.
