Can not load library?

[K-M-Ibrahim-Khalilullah]

I compiled from terminal using the following command:
g++ -std=c++11 -shared concaveman.cpp -o libconcaveman.so

but when I run the demo.py it produces the following error:
OSError: cannot load library 'D:/feasibilityAnalysis2020_3/Dpointcloud3Dvision/RemoveNoiseAndTIN/Code/ConCaveHull/concaveman-cpp-master/concaveman-cpp-master/src/main/cpp/libconcaveman.so': error 0xc1

is there any solution?
g++ version 8.1.0
python 3.6
cffi 1.14.0

Same problem here. Has anyone found a solution?

On my side I had the most silly error. When changing the hard-coded path to the '.so' library the was a typo in the path, left from copy pasting. Now it runs.
