Invalid MEX-file macOS

I have been trying to run ValoMC (https://github.com/InverseLight/ValoMC/archive/master.zip) for Monte Carlo simulations in MATLAB, but can't run it. I have followed the installation guide and am using Xcode as compiler, but when trying to run the example files I get the error:

How can I fix this?

Note: I've tried entering otool -L libMatlabEngine.dylib in the terminal but then this comes up: "error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/otool-classic: can't open file: libMatlabEngine.dylib (No such file or directory)"

Hello Tine,

As per my understanding, you are encountering errors while executing C++ MEX files on your macOS.

You can try the following workaround to resolve the issue you are facing:

Set the "DYLD_LIBRARY_PATH" environment variable to the path specified below:

‘matlabroot/extern/bin/maci64’

For more information on Run-Time Environment requirements for building C++ Engine programs, please refer the following link: https://www.mathworks.com/help/matlab/matlab_external/build-c-engine-programs.html#mw_4ec5bd7e-1127-41a8-844c-817cb7a9cae3

I hope that this helps resolve the issue you are facing.
