undefined symbol: _ZGVbN4v_expf on Fedora Linux

[nabobalis]

I am trying to import fguassian and I get the following error:

ImportError: /home/nabil/.local/share/mamba/envs/muse/lib/python3.13/site-packages/ftools/fgaussian/fgaussian_f32_ext.cpython-313-x86_64-linux-gnu.so: undefined symbol: _ZGVbN4v_expf

I use a Linux machine (fedora), gcc (GCC) 15.2.1 20251022 (Red Hat 15.2.1-3), Python 3.13.9 provided by conda-forge and numpy version 2.3.4.

I installed ftools by cloning the repo and running pip install . on the main branch.

I added

fgaussian_extra_link_args = ["-lmvec"]

which fixed it for me locally.
