cannot add SofaPython3 plugin on Mac M1 Pro

[garyxyz]

Hello everyone,

I am trying to add SofaPython3 plugin in runSofa UI through Edit->Plugin Manager->Add on Mac. But I met the following error

[ERROR]   [PluginManager] Plugin loading failed (/Users/h/Documents/programs/sofa/src/SOFA_v21.12.00_MacOS/plugins/SofaPython3/lib/libSofaPython3.dylib): dlopen(/Users/h/Documents/programs/sofa/src/SOFA_v21.12.00_MacOS/plugins/SofaPython3/lib/libSofaPython3.dylib, 0x000A): Library not loaded: /usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.9/Python
  Referenced from: /Users/h/Documents/programs/sofa/src/SOFA_v21.12.00_MacOS/plugins/SofaPython3/lib/libSofaPython3.1.0.dylib
  Reason: tried: '/usr/local/opt/[email protected]/Frameworks/Python.framework/Versions/3.9/Python' (no such file), '/Library/Frameworks/Python.framework/Versions/3.9/Python' (no such file), '/System/Library/Frameworks/Python.framework/Versions/3.9/Python' (no such file)

This seems like a Python path issue. I have Python at /opt/homebrew/bin/python3.9 and this is in the PATH. And my /usr/local/opt/ is empty.

Then I compiled the SofaPython3 with specifying python path. When adding the plugin through the Plugin Manager, it gives me
libSofaPython3.1.0.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))
I am using M1 Pro chip. Could anyone help me out?

Thanks in advance!

Thanks a lot

thanks a lot @garyxyz
we will investigate this with @guparan . Guillaume, will you need any more info here?

[hugtalbot]

Even if @guparan would bring more insight, it seems that the expected path to python ('/Users/runner/.../libpython3.9.dylib') and not finding any. If you have somewhere python 3.9 installed you could create a symbolic link between '/usr/local/lib/libpython3.9.dylib' --> your libpython3 location

dirty but could quick-fix this ..

[garyxyz]

i will give a try
thank you very much @hugtalbot and @guparan

[hugtalbot]

did you have the chance to test @garyxyz ?

[garyxyz]

Sorry for the late reply.
Yes, problem solved after creating a symbolic link to the my libpython3.
Thank you again.
