Re: [Sndobj-devel] SndCoreAudio fixes

Of course one must admit that possibility!
I didn't mention it but I did a _very_ thorough check of the entire
file system using:
cd / ; $ sudo ls -liR | grep -i libsndobj
and there is not a single i-node outside /usr/local/sndobj/
which does not refer to an email, manual etc file. (I ran the test
twice)
Furthermore when I move the libsndobj etc files from where scons
creates them,
python (import sndobj) fails, so I know I'm dealing w. the(recently)
created builds and not some
obscure reference via $PYTHONPATH or whatever.
Possible conclusions?
(a) HW error
- other SW works, so unlikely
(b) code error - possibly, but Tony says it works for him
- need to
- test Todd's build on my machine......
- determine exact SW version combinations
(c) some weird incompatibility problem w. scons/swig/python
- have returned to sys python 2.3,
- have installed latest scons under 2.3
- have built pysndobj under 2.3 using
$ cd /usr/local/sndobj ; sudo scons pythonmodule=yes
Given the above, would you still put money on it being a lazy SndObj
or relative?
Personally, I doubt it.
