Re: [Cs-dev] Sugar on a Stick - and OLPCsound

I've just noted that the /usr/lib/python2.6/site-packages folder does not include csnd.py. That folder also contains many fewer files that the corresponding one in python2.5.
 
As a matter of fact, python2.5 seems about a third the size of 2.6. Is all this correct?

Hello, Peter,
 
Do you know what may be happening here? (Please see error log below.)
 
I've no idea why the module referenced (csd.py) is not found. Please also compare the log at the very bottom of this mail; this latter log was generated when running Csound*5.08*, also with python2.6.
 
Thanks for any insights.

Here's the *next* chapter in the saga. Please note that this is not the *Windows* installation saga; it's the *Linux/Sugar* installation saga.
 
In our last episode, we noted that Csound5.08 was (apparently?) incompatible with python2.6. At least this seemed a plausible explanation from the error log we saw.
 
So, now Csound5.10 is available on Fedora(11) for download to SoaS.
 
First, I try update csound; "can't find any csound".
Second, install csound; it tries, but then says, "can't because it interferes with olpcsound" (OK, different name!)
Third, erase olpcsound; good
Fourth, install csound; good
 
Then I run my Activity; it now crashes with the similar, but not exact, error log below.
 
I thought perhaps I'd better start from scratch and did (reformat USB drive, etc). Thought probably the new SoaS iso incorporated Csound5.10. But no, I needed to essentially repeat the above steps, and ended with the same crash.
 
The log: (any new ideas please?)

Because the 5.10 rpm has a python2.6 dependency. But that might
be the case for 5.08 too (I am not sure).

I just noticed that the current OLPC build includes Python 2.5, whereas SoaS includes Python 2.6
 
Csound 5.08.91 is currently in both. Wouldn't this explain why 5.08.91 doesn't work on SoaS? And why 5.10 should?

The message is strange, but it does not say there is a Python
version mismatch. However, having said that, the 5.08.91
rpm was built with 2.5 (unless what you have there is another
build that somehow uses 2.6).

What the message says is that the library module Python
tried to load does not have one of the API functions. The
reason for this I don't know.
