AttributeError: 'BoxSizer' object has no attribute 'AddStretchSpacer' running usrp_fft.py

GNU Radio

Hello all. I am new to gnuradio. I installed gnuradio on a three
computers
(a) an Ubuntu 6.06 P4-mobile laptop, (b) an Ubuntu 8.04 Dell SX270 mini
desktop, and © an Ubuntu 8.04 Dell Precision 560 dual Xeon-2.4GHz. On
each
machine I compile from source following the install directions for
Ubuntu on
the FAQ. On (a) everything runs perfectly, on (b) the command-line based
stuff works, but the GUI always fails out with some error like the one
shown
below before starting, on © same as (b). I am working with the usrp
hardware and have tried it with two different motherboards (both version
4.1) – both work correctly on (a) and give the same error messages on
both
(b) and ©. I’ve copied an example trace below. I get different errors
for
different gui’s. QWT-5.0.2 was installed from source per the FAQ. I
modified
/etc/lib.so.conf to include /usr/local/lib per the FAQ as well.

Thanks! -Jonathan

SOLVED. There is an error with the FAQ at
http://www.gnuradio.org/trac/wiki/UbuntuInstall

The recommended packages install for Hardy (and several other versions)
is:

sudo apt-get -y install g++ automake1.9 libtool python-dev fftw3-dev
libcppunit-dev libboost-dev sdcc libusb-dev libasound2-dev
libsdl1.2-dev python-wxgtk2.6 subversion guile-1.6 libqt3-mt-dev
python-numpy-ext

Which as you can see incorrectly refers to “python-wxgtk2.6”. The
correct package is “python-wxgtk2.8”. The error messages occur because
some functionality required by usrp gui’s was not yet implemented in
version 2.6… such as the addStrechSpace() method of the Sizer class.

Cheers,
-Jonathan

Good catch. I’d recommend updating the Wiki (l/p guest/gnuradio), but
apparently there seems to be an issue with Trac:

Oops...
Trac detected an internal error:

database is locked

Hopefully that can get resolved and the instructions can be updated.

Seems to be working as of now.
