Description

$ python test_amgx.py
Traceback (most recent call last):

    import pyamgx
  ImportError: /toolbox/guyer/AMGX/build/libamgxsh.so: undefined symbol: omp_get_num_threads

It works with AMGX v2.3.0

test_amgx.py is pyamgx demo code.

Research direction

Start by reproducing the import failure with test_amgx.py and inspect the reported build/libamgxsh.so error for the unresolved omp_get_num_threads symbol. Compare the current HEAD build with AMGX v2.3.0, where the demo works, and verify that importing pyamgx succeeds without the undefined-symbol error.
