Hello, Peter,

I don't know whether Aleksey's post to the sugar-devel list (regarding a 
Scons fix) helped understand why Csound5.10 isn't working in SoaS. 
(Unfortunately my technical level doesn't reach anywhere near - to 
understand Aleksey.)

Regarding testing, however: I'd be happy to test anything, or send you the 
.xo I'm working with (OurMusic.activity). Or there is Victor Lazzarini's 
csndsugui (git) package, which includes 4 activities - particularly his 
Waves.activity is a great test.

Just run the activity and see whether a screen comes up, nothing more. 
Problem solved if it does.

I suspect there are two basic issues:
1) Csound5.10 was designed to interface with python2.6; csound5.08 and 
earlier, with python2.5
2) The name change from olpcsound to csound

Thanks for all your work in updating Csound for the SoaS project.

I think it might be a combination between the Fedora package and the
way upstream deals with python (and probably the Fedora move to python
2.6). When I updated the package I asked on a number of olpc related
mailing lists for people to test it and only got a couple of
responses, all positive. I'm going to have a look at some of the
patches that were ported from 5.03 to 5.10 later this week to see if
there was anything missed but there is only so much testing i can do
myself if people ignore requests.
