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

[Jonathan Friedman]

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 (c) 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 (c) 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 (c). 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
