Re: [Discuss-gnuradio] New OpenGL-based FFT, Waterfall, and Scope displays in trunk

[Firas A.]

Hi,

1) Great Work.

2) I think screen refresh (drawing times) is too high (on my system) that
leads to flickering.

3) Compiling a fresh trunk copy (rev 9311) on my C2D running Ubuntu 8.04,
the running of usrp_fft.py for the first time leads to the following error :

 File "./usrp_fft.py", line 306, in <module>
    main ()
  File "./usrp_fft.py", line 302, in main
    app = stdgui2.stdapp(app_top_block, "USRP FFT", nstatus=1)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui2.py",
line 36, in __init__
    wx.App.__init__ (self, redirect=False)
  File "/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/_core.py",
line 7836, in __init__
    self._BootstrapApp()
  File "/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/_core.py",
line 7433, in _BootstrapApp
    return _core_.PyApp__BootstrapApp(*args, **kwargs)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui2.py",
line 39, in OnInit
    frame = stdframe (self.top_block_maker, self.title, self._nstatus)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui2.py",
line 60, in __init__
    self.panel = stdpanel (self, self, top_block_maker)
  File "/usr/local/lib/python2.5/site-packages/gnuradio/wxgui/stdgui2.py",
line 81, in __init__
    self.top_block = top_block_maker (frame, self, vbox, sys.argv)
  File "./usrp_fft.py", line 122, in __init__
    self.scope = fftsink2.fft_sink_c (panel, fft_size=1024,
sample_rate=input_rate, 
AttributeError: 'module' object has no attribute 'fft_sink_c'

as mentioned in "README.gl", creating the file ~/.gnuradio/config.conf
removed the error and everything was working fine in the second usrp_fft.py
shot. I think this file should be creating automatically with the option
style=gl (or at least style = auto)


Best Regards,

Firas
