Hello all,
Yesterday I did a gnuradio update (./pybombs update) and noticed my
version
went back a minor version. I had been using 3.7.8 and now I’m using
3.7.7.1.
I’ve created flowgraphs using 3.7.8 that are not working with 3.7.7.1. I
don’t get any debug information, I click the play button and it sits
there
and then exits with code -8.
I’m wondering what happened. I know I didn’t do anything special to get
3.7.8, but now I’d like to get it back. Can someone advise me on how to
do
this.
Thanks,
Rich

I’m suspecting a drift in the space-time continuum. Or did you enter a
blue box by any chance that was bigger on the inside than on the
outside? 
Sci-fi aside, 3.7.8 is not yet released, but our master branch is
versioned 3.7.8git (more precisely: v3.7.7.1-131-g71ab508d / 3.7.8git).

Install latest HEAD from master.

I can’t explain how it happened Martin. I can not comment on the blue
box,
they won’t let me…
Joking aside, I don’t know how it happened. Prior to yesterday, with GRC
open, when I went to help->about it told me I was using 3.7.8. I’ve had
access to things like the new correlation estimator block and modulate
vector block, which I understand are 3.7.8 toys from previous mailing
list
conversations I’ve had. Correct me if I’m wrong. Now help->about shows
3.7.7.1.
Pybombs handles the typical problems the link you posted addresses, like
compile order and re-compiling in general. It uninstalled both uhd and
gnuradio and then re-installed them both. Older flowgraphs work, but the
ones using modulate vector and correlation estimator don’t. I do have
some
custom blocks in those flowgraphs, would I need to re-build all custom
blocks after an update?
Is it possible pybombs pointed to 3.7.8 by mistake for a day or two at
some
point, which happened to be when I last updated? How would I tell
pybombs
to install master HEAD, or are you recommending a git pull on gnuradio
directly?

You might not, but if ABI breaks, things go bad.

Maybe…? I don’t know. Anyway, I suggest since you’re getting into GR
development and all that you simply build by hand the branch you need
(i.e. master) and you should be fine.
