Forum: GNU Radio Problem in the update

Hi everyone,

I made an update of gnuradio in my university lab computers. They were 
using
the 3.4.1 version, and I changed it to 3.5.3 version. However, some of 
the
programs made for the old versions stopped working. When I run the 
script
made by another student for the old version, I get this error:

traceback(most recent call last):
(...)
File 
"/usr/local/lib/python2.6/dist-packages/gnuradio/blks2impl/gmsk.py",
line 223, in __init__
     self.clock_recovery = gr.clock_recovery_mm_ff(self._omega,
self._gain_omega,
AttributeError: 'module' object has no attribute 'clock_recovery_mm_ff'

Which is basically saying that a script installed by the gnuradio
installation itself
(/usr/local/lib/python2.6/dist-packages/gnuradio/blks2impl/gmsk.py) is 
still
working with the old methods since 'clock_recovery_mm_ff' doesn't exist
anymore.

Does this mean that the installation wasn't well made?

No, there was an API change (this was announced, though). 
clock_recovery,
among other things, was moved to gr-digital.

Try self.clock_recovery = digital.clock_recovery_mm_ff(...)

(of course, you have to 'from gnuradio import digital').

Good luck

Ok. But shouldn't gmsk.py and other scripts that come with gnuradio be
updated when there is an update? Does this mean that some other scripts 
.py
that comes with the installation of gnuradio are also outdated and don't
work if I don't change them?

My bad, I thought the error came up in your own script.
gmsk.py was updated to reflect the API changes, so I guess your update
is corrupted after all. If in doubt you should probably nuke all of your
GNU Radio files and reinstall.

Your own script should have an 'import digital' command. You shouldn't
be able to import gmsk (or other digital modulators) from anywhere else
than digital, or you know for sure your installation is botched.

In fact, I should have responded to this line in the first place. This
file should *not* exist after the update. Looks like you did something
wrong while removing the old files before updating.

Yeah. I used the build-gnuradio script that says that it removes the old
versions. Probably there was some error in the installation that I 
didn't
notice...

It removes anything that was installed from binary *packages*. But
if you have a previous source install, it doesn't go around trying to
hunt down all the artifacts from that install and try to remove them.
That would be really hard, because the new gnuradio source pack won't
include uninstall instructions for the old install, and the old install
source lump may not be lying around, so there's no "manifest" for it to
work from.

Ok got it.

Now I am trying to uninstall gnuradio. I am a bit nervous because it is 
my
first uninstall and the computer isn't mine.

I am doing as http://gnuradio.org/redmine/projects/gnuradio/wiki/FAQ 
tells
me, however, I can't find anything with the name gnuradio or similar in
these folders: /usr/bin, /usr/lib(64). Furthermore, I don't have the 
folder
/usr/local/lib(64) in the computer. I wonder if this is normal

I just want to check before starting deleting files. I don't want things 
to
get worse than they are right now

If you want to get every last file, and you know exactly how the old 
version
was compiled (ideally down to the ./configure command) then you could 
always
download that old version, compile it, then run 'make uninstall'.  This 
will
remove all the files that would have been installed, so if it matches 
your
original config, every last file in your existing gnuradio installation 
will
be removed.

Of course that's probably overkill, and if you just move the files to 
another
folder instead of deleting them, then you can always move them back if
something breaks.  In answer to your question, often /usr/local is empty 
until
you start installing things yourself, so having no /usr/local/lib is not 
unusual.

But if you're going to do the install on lab computers (where presumably 
there
are a number of identical ones) you'd probably be better off taking the
opportunity to make a package for whatever OS you're running.  Then you 
can
install the same package on all your machines quickly, and when the time 
comes
to do the next update the package manager will take care of removing the 
old
files for you.

Cheers,
Adam.

Ok. Thanks for the tips.

I had to remove gnuradio manually because no make uninstall was working.

Right now, I am trying to install the old version. That might seem odd 
but
the program I have to show working friday, which wasn't made by me, only
works for the old version. I tried to adapt it to the new version and it
runs however, it doesn't have the same behavior has it had for the old
installation. Since it wasn't me who did the code I feel safer using the 
old
version for now.

I've found the gnuradio installation folder used by someone before me. I
installed the 3.4.1 version with it. However it didn't install the uhd.

The instructions I found for installing the uhd seem to install the 
newer
version. However, I want the version that works with 3.4.1. Any 
suggestion?
