[Discuss-gnuradio] Re: AttributeError: 'BoxSizer' object has no attribute 'AddStretchSpacer' running usrp_fft.py

[Jonathan Friedman]

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
