[Discuss-gnuradio] scopesink, wxgui, Mac OS X

[Jonathan Jacky]

Has anyone got scopesink.py (or any of the other demos in wxgui) working
under Mac OS X?

I've installed gnuradio, wxPython, and all their prerequisites on Mac
OS X (versions given below).  Each works by itself.  I can run
gnuradio without the GUI (using file sinks to write the output, which
I can display in gnuplot), and I can run the wxPython demos that come with
that distribution.

But I can't run them together - when I try "pythonw scopesink.py", or
the other demos in wxgui --- fftsink or waterfall --- I get a crash
and traceback (sample below).

The wxgui programs get pretty far before they crash.  scopesink
displays the scope window and plots the two sine waves (sometimes just
one).  The traceback suggests that it crashes when it tries to clear
the display to draw the next trace.

This suggests to me that there is nothing missing or grossly
misconfigured in my installation.  Perhaps I have the wrong
combination of versions of the many packages I have installed.  Or
maybe there are portability problems in scopesink.py or plot.py or
elsewhere in wxgui (I am not sufficiently experienced with Python to
know if this is likely or even possible).

So, before I begin digging into this, I would be interested to learn
wether anyone else has succeeded in running scopesink.py under Mac OS X.
If they could tell me what versions they were running, I would be
especially grateful.

Here is the software I installed, in this order:

 Mac OS X "Panther", 10.3.7, Darwin 7.7.0, with GCC 3.3, Python 2.3

 darwinports from http://darwinports.com
 autoconf 2.59_0 and automake 1.9.4_0 from darwinports
 swig 1.3.22 from http://www.swig.org/
 libtool 1.5.2 and libtoolize 1.5.2 from darwinports
 pkgconfig 0.15.0 from darwinports
 fftw-3 3.0.1-fma, Revision 2 from darwinports
 boost 1.31.0 from darwinports
 cppunit 1.10.2 from http://cppunit.sourceforge.net

 GNU Radio 2.X from CVS, Jan 11, 2005

 wxPython 2.5.3.1, Mac binaries (.dmg) from www.wxPython.org
 numarray 1.1.1 source tar from sourceforge.net/projects/numpy
 Numeric 23.7 source tar from sourceforge

Here is the traceback I get when I try "pythonw scopesink.py".  It
seems to include three separate tracebacks --- I'm not sure what that
means.
