RESOLVED: "Problem Report / TD cannot be opened" behavior related to OpenCV changes on MacOS

Bugs
1

Build 2021.13610 on MacOS 10.15.7

I receive the MacOS ‘Problem Report / App cannot be opened’ screen launching TD. Report details (complete below) include this error:

“”"
Termination Reason: DYLD, [0x4] Symbol missing

Application Specific Information:
dyld: launch, loading dependent libraries

Dyld Error Message:
Symbol not found: __ZN3tbb4task13note_affinityEt
Referenced from: /Applications/TouchDesigner.app/Contents/Frameworks/libopencv_world.4.5.dylib
Expected in: /usr/local/lib/libtbb.dylib
in /Applications/TouchDesigner.app/Contents/Frameworks/libopencv_world.4.5.dylib
“”"

Based on this, I suspect this happened following recent installation of OpenCV v3 libraries with Homebrew, using the command ‘brew install opencv@3’.

I have tried uninstalling all traces of OpenCV 3 & 4 and TD, and reinstalling only the current build of TD, but still receive the error. I tried installing experimental build 2020.46540, and that worked. Subsequent installation of the current build then fails again.

I also installed the current build on a similar Mac that did not have any OpenCV installations, and TD opens.

I’m stumped – any ideas how to track down what has changed?

Thanks.

The problem is the file /usr/local/lib/libtbb.dylib, which is for some reason getting loaded instead of the libtbb.dylib that we have located in our installation directory. If you remove/rename that file, that will fix things.

removed and fixed too, thank you!

Thanks, in future builds this won’t be necessary.

Had the same issue in 13610 after messing around with homebrew and opencv.

$ rm /usr/local/lib/libtbb.dylib

totally fixed it, thanks Malcolm!
