[Quantlib-users] Issue building QuantLib-SWIG-1.36

[Matthew H. <mat...@gm...>]

Hi QuantLib team, 

I am running into an issue building QuantLib-SWIG-1.36 on a Mac M1 running Mac OS 10.14. I am using an Anaconda version of Python 3.8. 

I can build QuantLib-1.36 with no issue (I added the --disabled-shared flag).

However, when I build QuantLib-SWIG-1.36 and try to import the Python library, I get an import error: 

>>> import QuantLib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/matthew/opt/anaconda3/lib/python3.8/site-packages/QuantLib-1.36-py3.8-macosx-10.9-x86_64.egg/QuantLib/__init__.py", line 19, in <module>
    from .QuantLib import *
  File "/Users/matthew/opt/anaconda3/lib/python3.8/site-packages/QuantLib-1.36-py3.8-macosx-10.9-x86_64.egg/QuantLib/QuantLib.py", line 10, in <module>
    from . import _QuantLib
ImportError: dlopen(/Users/matthew/opt/anaconda3/lib/python3.8/site-packages/QuantLib-1.36-py3.8-macosx-10.9-x86_64.egg/QuantLib/_QuantLib.abi3.so, 0x0002): symbol not found in flat namespace '__ZN8QuantLib12SmileSection6updateEv'

Any help would be much appreciated, thanks! 

Best
