Hi there! While testing my plugins foung that zlib python module not loading on MacOs BigSur 11.1 on R23.110. On Windows 10 same C4D version it works fine.
>>> import zlib Traceback (most recent call last): File "console", line 1, in <module> ImportError: dlopen(/Applications/Maxon Cinema 4D R23/resource/modules/python/libs/python37.macos.framework/lib/python3.7/lib-dynload/zlib.cpython-37-darwin.so, 2): no suitable image found. Did find: /Applications/Maxon Cinema 4D R23/resource/modules/python/libs/python37.macos.framework/lib/python3.7/lib-dynload/zlib.cpython-37-darwin.so: mach-o, but wrong architecture /Applications/Maxon Cinema 4D R23/resource/modules/python/libs/python37.macos.framework/lib/python3.7/lib-dynload/zlib.cpython-37-darwin.so: mach-o, but wrong architecture >>>
Hi @mikeudin,
Unfortunately, there is nothing you can do on your side, we are going to look at the issue and try to resolve it as soon as possible.
Just a guess for a possible workaround (as I don't have any ARM to test stuff) is maybe to install python3.7 on your ARM mac and simply copy the zlib.cypthon-37-drawing.so. This may cause issues due to the notarization (but it should work once you allowed the library to be loaded in your mac System preference).
EDIT: But since Python announces Big Sur support only for Python 3.9.1 it might be that there is simply no zlib ARM ready shipped if you install a Python 3.7.7 version.
Cheers, Maxime.
Hi @mikeudin we just found out that if you enable Rosetta mode (Right click on Cinema 4D executable -> Get Info -> Check Enable Rosseta Mode) it does load also dynamically linked libraries in Rosetta Mode
This is of course a workaround and a bug report was filled in order to fix the issue as soon as possible. Cheers, Maxime.
@m_adam Thank you!
@m_adam same issue with bz2 and gzip modules
Correct here are all the one we expect to fail:
As a quick reminder, Python 3.7.7 doesn't officially support M1, and only Python 3.9.1 (released in December does fully support it).
