[Discuss-gnuradio] all's ok, but unable to execute an example...

[Norbert François]

Hi List,

I'm totally new to gnu-radio (and python in general). I've successfully installed (make && make install). My ./configure gets me: 


config
omnithread
gnuradio-core
gr-audio-alsa 
gr-audio-oss
 gr-atsc
gr-gsm-fr-vocoder
gr-pager
gr-radio-astronomy
gr-trellis
gr-video-sdl
gr-wxgui
pmt
mblock
gr-rdf
gnuradio-examples

You my now run the make command to build these components. 

*********************************************************************
The following components were skipped either because you asked not
to build them or they didn't pass configuration checks:

usrp 
 gr-usrp
gr-audio-jack
gr-audio-osx
gr-audio-portaudio
gr-audio-windows
gr-comedi
ezdop
gr-ezdop





I don't need more things for what I'm gonna do (just a fft and add a filter on a signal, to use on a gnuradio box further on).  

But now, when I try to execute, for instance:

#gnuradio-examples/python/audio/noise.py

I get:

I'm  running a gentoo box    
2.6.19-r5. I installed manually all required packages (and set the path to PYTHONPATH=/usr/local/lib/python2.4/site-packages/).

Thank a lot for your help !
