Trying to create a python library that outputs a geoTIFF using the `geotiffwrite` function
compiled library runs smoothly on windows but errors on linux (Ubuntu 20.04.4 LTS)
compiled on MATLAB R2022a Update 2
Here's the error it outputs:

ret = futureresult.FutureResult(self._cppext_handle, future_tuple, nlhs,

I meet the same error like this 'Invalid MEX-file, ... libmwtiffmexutils.so: undefined symbol: MWTIFFRegisterFunctionPointers'. My problem is that I compile on a win10 machine and deploy it on a centos7 server, they use different underline compiler. After I recompile in a centos7 server installed with Matlab Compile SDK, it works.
