Greetings,

When I tried to run Rationale I received this error :

dlphilp@The3800:~/src/rationale-0.2> python rationale.py
Traceback (most recent call last):
  File "rationale.py", line 40, in 
    import csnd
  File "/usr/lib/python2.5/site-packages/csnd.py", line 5, in 
    import _csnd
ImportError: dynamic module does not define init function (init_csnd)


The same error occurs on 32-bit and 64-bit Linux boxes with Csound 5.10 
compiled for double precision.

Any suggestions for a fix ?

This looks like the usual "Python can't find Csound" error.
Can you run other Python/Csound apps? (e.g. wxController.py)

Grrr.... Nope, wxController.py didn't work either. The installation of 
5.10 here is by the book, csnd.py is in the right location, but 
obviously something didn't get put in the right spot.

So what's to do next ?

I seem to recall that you had this issue recently too (a few weeks or
months back), did you fix it by manually creating a symlink? (maybe I
don't remember correctly?). I remember that you had done everything by
the book bac kthen also, and I was surprised that the Python csnd
module could not be found on Linux after a standard install procedure.

This should really work out of the box, the install procedure for
Linux should be checked.
Sorry not to be of more help.

Hi Oeyvind,

Thanks for your attention, I appreciate it. Alas, my former trick of 
copying libcsnd.so to /usr/lib did nothing to help, I get the same error 
regarding the init function.

It really is kind of ridiculous. The same error occurs on two machines, 
both of which have Csound 5.10 installed as per the official 
instructions, and I always end up with a PITA re: Python finding stuff. 
Is the problem with Python, Csound, or both ?

Well, I'm at a loss again. Anyone have further suggestions ?

Best,

dp

Thank you, Victor, that was the key. The PYTHONPATH included only 
/usr/lib/python2.5, nothing else. I added my Csound build directory to 
that path, Rationale 0.2 now opens and appears to be functioning properly.

Sheesh. Sorry for the noise.

Best,

Should the setting of PYTHONPATH be automated when installing on Linux ?

There should be no need for that, if _csnd.so and csnd.py go into
the usual site-packages directory.

Good. I'm curious about this because of 2 things:

1) if _csnd.so & csnd.py are in /usr/lib/python2.5/site-packages
you should not need to set PYTHONPATH

2) The error you reported does not make too much sense
to me: if _csnd.so was found it should contain init_csnd

ImportError: dynamic module does not define init function (init_csnd)

Regards

Victor

Good to know; if you had this issue I can only expect other people
will.  I would bet most Rationale users won't have previous Csound
installations, though, if that was part of the problem.
I'm glad to hear it works so far.
