Problem using usrp_fft.py in Suse 10.2 64 bit

GNU Radio
1

Hello,

I got my new Core 2 Duo system up and running with GNURadio. When I
installed Suse 10.2 64 bit I also selected install the 32 bit packages.

My Mode S code works and usrp oscilloscope work but when I run the
usrp_fft.py I get a constant error message and no display. The error is
in line 276 of fftsink.py with the call to Numeric.concatenate. The
error message is:
ValueError: matrices are not aligned for copy.

I noticed the path is
/usr/local/lib64/python2.5/site-packages/gnuradio/wxgui/fftsink.py

Is this a problem with using 64 bit python versus 32 bit python?

Hello,

Some more information.

When I setup my Core 2 Duo system I got GNURadio code from the main
trunk. The laptop was using an older version of the main trunk and did
not have a problem. A couple of days ago I updated the laptop from the
current main trunk and now I get the same problem with fft. I also find
problems with oscilloscope on both systems if I select certain timebase
entries.

I suspect a recent change caused this and likely the example code needs
to be updated. I may look at it over the next few days in my hotel room
to kill time.

I got the same behaviour an errors yesterday on a Core2 Duo.

Wich revision did you use before updating?

This error (fft not wroking and matrices not aligned) seemes to have
occured before:
