runtime_client compiled shared library not working

[garysassano]

I clone the repo and run python setup.py bdist_wheel, then I upload the awslambdaric as a layer and try to execute it, but I get an error. I replace the runtime_client.cpython-39-x86_64-linux-gnu.so file with the original one provided by AWS and it works. I don't understand why the shared library compiled by me doesn't work.

This is the function log:

You need to build a wheel using manylinux2014 Docker image in order to make the package work on most Linux distros, and that's actually what's being distributed on PyPI.
