I'm having issues with ctcsound on Linux. I just can't get it to play ball. Here's the output:

>>> import ctcsound

Traceback (most recent call last):

    func = self._FuncPtr((name_or_ordinal, self))

AttributeError: libcsnd6.so: undefined symbol: NewCsoundPT

I just built from the dev branch? I will try from the master branch and see if that's any better..

For what it's worth, it doesn't run out of the box on OSX either, although the error is different. I get the following error after installing the very latest version of Csound for OSX. 

>>> import ctcsound

Traceback (most recent call last):

    self._handle = _dlopen(self._name, mode)

OSError: dlopen(CsoundLib64.framework/CsoundLib64, 6): image not found

I fail to see how it can't find the image when running Csound from the command line works just fine.

Hello Rory,

I just built on linux (Ubuntu 16.04) from the develop branch and I could not reproduce your problem. Maybe there's an old version of libcsnd6.so remaining somewhere in your system?

I think the ctcsound.py is not the one installed by the installer, but a manually installed with make install.

The installer places things in /Library/Python

and not in ~/Library/Python.

Remove that file and try again

Which version of Numpy? It seems it's a known bug between numpy and ctypes. See https://github.com/toinsson/pyrealsense/issues/82. I had recently this issue on a linux ubuntu 18.04 system. I installed anaconda and this solved the problem. What puzzled me was that this bug was referenced in 2013. It seems it re-appeared in recent versions of ctypes.

when you run the python command does it say that it is the python from anaconda? Something like that:

Python 3.6.5 |Anaconda, Inc.| (default, Apr 29 2018, 16:14:56)
