I haven't tested this yet, but I am most eager to do so next time I
need the python interface. It is also neat that it seems too ease the
transition to Python 3.
Is there any reason why ctcsound should not replace csnd6 as the
default (distributed/installed) python interface to Csound? How easy
is it to port existing examples from csnd6 to ctcsound?

I think we can have both side-by-side for now and then put csnd6 to bed when we release Csound 7.00.

The line


should work on standard installations. However, there seems to be a problem:

ligeti:ctcsound victor$ python test_ctcsound.py 
Traceback (most recent call last):
  File "test_ctcsound.py", line 24, in 
    import ctcsound, numpy as np, ctypes as ct
  File "/Users/victor/src/ctcsound/ctcsound.py", line 2350, in 
    libcspt.NewCsoundPT.restype = c_void_p
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 378, in __getattr__
    func = self.__getitem__(name)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 383, in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: dlsym(0x102507cd0, NewCsoundPT): symbol not found

I checked and the symbol is there:

ligeti:ctcsound victor$ nm /usr/local/lib/libcsnd6.6.0.dylib  | grep "NewCsoundPT"
0000000000016b10 t _NewCsoundPT

I checked also that this is the library that is being loaded (by removing it and causing the python script to fail).
Do you have any idea?

Hi,

Maybe it was covered in previous emails -

I must also check if ctcsound works inside CsoundQt, bug I guess, it should.

Thank you!
