undefined symbol: _ZN5model6Engine10ParseSpecsEN6config18CompoundConfigNodeE

Hello, I've tried to install gamma with timeloop, and the installation seems to be successful. But when I run the example scripts by bash run_gamma_timeloop.sh and bash run_gamma_timeloop_multiObjective.sh, there's an ImportError caused by undefined symbol.

The complete log is as follows.

root@83fe54e1ae36:~/gamma-timeloop# bash run_gamma_timeloop.sh Traceback (most recent call last): File "/root/gamma-timeloop/src/main.py", line 1, in <module> from gamma_timeloop_env import GammaTimeloopEnv File "/root/gamma-timeloop/src/gamma_timeloop_env.py", line 7, in <module> from timeloop_env import TimeloopEnv File "/root/gamma-timeloop/src/timeloop_env.py", line 9, in <module> from pytimeloop.app import Model File "/root/pytimeloop/pytimeloop/__init__.py", line 1, in <module> from bindings import * ImportError: /root/pytimeloop/bindings.cpython-39-x86_64-linux-gnu.so: undefined symbol: _ZN5model6Engine10ParseSpecsEN6config18CompoundConfigNodeE

Hi, I have the same issue, and it is related to pytimeloop, take a look here:

https://github.com/Accelergy-Project/timeloop-python/issues/29

For now I managed to circumvent it by using the Docker container provided with Timeloop (see here), however you need to manually build barvinok and install it inside the container, but that's easy by following the same commands as the Makefile for Timeloop's infrastructure: https://github.com/Accelergy-Project/accelergy-timeloop-infrastructure/blob/1f6bf7cf0071d43e87d5351be3ff960f03af523d/Makefile#L159

I know it's been 4 months, but maybe I could still help. Let's trust the pytimeloop guys to fix this issue sooner or later.
