Ubuntu 11.10

GNU Radio

The maint, master, and next branches in git have all been fixed to work
under Ubuntu 11.10 (new autotools and Qwt 6 were the main culprits). A
bit

Do I need to install /swig/ or /swig2.0/ from the repos as dependencies
to build from source ?

You want the “swig” package, which looks like it is version 1.3.40.

You do NOT want swig2.0 (although hopefully they can coincide). We have
not
made the change to 2.0 and don’t plan to in the near future. It looks
like
it will be a good move when we do, but I would like to basically build a
lot
of things from the ground up as opposed to trying to patch what we have
into
working with 2.0 since a lot of hacks we have in our system look like
they
have been officially fixed/supported in the new version. The move to
using
2.0 will be a pretty big announcement when it happens, but it won’t
likely
happen until we’re either forced to do it or all of our supported OSes
support it.

I tried to switch to qwt6. So, I cant find python-qwt6 in the repos
(this is for some of the grc qt widgets). So I guess that is a minor
disappointment.

And I got this compilation error. Any idea?

Yeah, I know exactly what the problem is. I just found it myself. It
arose
after I fixed some edits to be compatible with 5.2, but didn’t do it
right
to keep it working with qwt 6. I must not have properly updated my 11.10
box
afterwards to check it.

I just pushed what I believe are fixes to maint/master/next. Let me know
if
anyone has problems with either Qwt versions 5.2 or 6.0.

The push to next also includes a bunch of updates to gr-digital where
I’ve
moved all of the OFDM work into gr-digital and reworked all of the
examples
to use UHD. Again, let me know if people experience more than the usual
issues :slight_smile:

python-qwt5-qt4 seems to work ok

And I got this compilation error. Any idea?

Here is my attempt to get it working. It compiled for me and ran. I
didnt quite know what to do with rasterHint though…
