Hi Joachim,
I got a step further. I linked the anaconda library libpython3.6m.dylib against the framework library requested:
sudo ln -s /anaconda3/lib/libpython3.6m.dylib ./Python
Now I can successfully start "netgen". However, when I try to import netgen or ngsolve to python3, it always crashes:
Python 3.6.5 |Anaconda, Inc.| (default, Apr 26 2018, 08:42:37)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from ngsolve import *
Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6
Do you might have another advice concerning this error?
Thanks and best regards,
Christoph
