Description
I'm attempting to "freeze" an application into a distributable OS X .app using py2app. I have slimmed my code down to the bare minimum which triggers this issue, but I don't understand enough of the magic to determine if the problem is truly with sounddevice, CFFI, py2app, or my configuration. Apologies if this is the wrong channel to start looking for a fix!
Once frozen, a simple import sounddevice causes the blowup. The exception is thrown when a C header is fed to CFFI as a giant string literal:

My setup.py with py2app configuration is as follows; I've explicitly included the path to my compiled PortAudio lib (which magically installed with sounddevice) to ensure it is included within the the .app:
from setuptools import setup
PY2APP_OPTIONS = {
'argv_emulation': False,
'includes': ['sounddevice'],
'frameworks': ['/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_sounddevice_data/libportaudio.dylib'],
}
setup(
app=['sdtest.py'],
options={'py2app': PY2APP_OPTIONS},
setup_requires=['py2app'],
)And the sdtest.py file itself need only be as simple as this to trigger this problem:
import sounddeviceCan you provide any suggestions as to how better to track down the problem here? I don't really understand what CFFI is doing under the hood, nor understand "who" is unable to find source code nor what source it's looking for.
