Are these bindings supposed to work with the Geant4 conda-forge package?

[HealthyPear]

The installation went fine, but the example usage failed,

In [1]: from geant4_pybind import G4UIExecutive

No idea about Macs and OS X but this came up when I googled your error:
https://stackoverflow.com/questions/71174306/expected-in-usr-lib-libc-1-dylib-installing-tensorflow-on-m1-macbook-pro

Might be some architecture or OSX version mismatch

I tried to build & install geant4_pybind for the Geant4 package installed via conda-forge on macOS 14.3. The Geant4 package is built with the GEANT4_BUILD_TLS_MODEL=global-dynamic option set.

After installing Geant4 via conda-forge, I also had to install zlib, xerces-c, and freetype packages using Homebrew to avoid build process failures. Furthermore, I also had to run export CMAKE_PREFIX_PATH=/usr/local/opt/zlib so that CMake could locate the correct zlib package. After these, the build process went through successfully.

However, when I try to run an example, I get segmentation fault.

The output of python -X faulthandler exampleB2a.py is:

Do you have any idea what might have gone wrong here?

Edit: I should add that I can install the package via pip and run examples without a problem. The above issue only happens after installing from source.

I'm not sure how conda works on MacOS, but it might be that the conda geant4 package was linked against a c/c++ library shipped with conda while the packages you installed with hombrew are linked against the system c/c++ library. Might be worth trying out whether you can install those additional packages via conda-forge instead. Also make sure you are in the conda environment when building the bindings.
