I have enjoyed Cabbage and CsoundQt for a quite a while, but wanted to use a Python API to do some more complex stuff with interfacing Csound with different python controlled hardware. I am a currently using a raspberry pi for my project. Unfortunately, I am a novice with building programs and generally in installing things in linux and so I am seriosuly struggling to get ctcsound to work.  

I created a symlink to libcsound64.so.6.0 in usr/lib as suggested in the following thread...

https://github.com/csound/ctcsound/issues/6

and I still get an AttributeError: /usr/lib/libcsound64.so: undefined symbol: csoundCompileTreeAsync

according to the github thread this is associated with using the wrong version of ctcsound, but I used the ctcsound.py file from my csound-6.13.0/interfaces folder, not github so I am confused as to why I am still getting this error.  

If anyone has ideas of how to fix this problem I would be very thankful.

Hi Mike,

I think the problem might be that the ctcsound.py you are using is a newer version
to the csoundlib you are linking to.

The error msg says ctcsound can't find a
certain API function that was probably introduced in a later version of Csound.

François might know more.

How did you install Csound on the Rpi?

Did you do a 'sudo apt-get update' and a 'sudo apt-get upgrade' first?
