move to meson build system

[trichter]

Occasionally we should move from numpy.distutils to meson. I think telewavesim cannot be installed alongside python3.12 due to setuptools/numpy.distutils conflicts. numpy.distutils is also removed from numpy.

Hi there,
I have troubles installing telewavesim as I run in the following error, while trying to install it via pip:

Preparing metadata (setup.py) ... error
error: subprocess-exited-with-error

× python setup.py egg_info did not run successfully.
│ exit code: 1
╰─> [6 lines of output]
Traceback (most recent call last):

File "", line 34, in
File "~/src/Telewavesim/setup.py", line 3, in
from numpy.distutils.core import setup, Extension
ModuleNotFoundError: No module named 'numpy.distutils'
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

As I think this is related to the issue trichter pointed out above I hope someone knows a way to fix this.

As a work-around you can try to install in a conda environment with an old numpy and python version.

The following is working for me:

conda create -n telews -c conda-forge "python=3.10" "numpy<1.22" obspy pytest fortran-compiler
conda activate telews
pip install telewavesim
pytest -v --pyargs telewavesim  # run tests

Thank you for your quick reply, we did the same here as a workaround and setup an environment with python 3.10.

On MacOS (x64), the above work-around installation still fails. I have found that the following works, using much earlier versions:

conda create -n telews -c conda-forge "python=3.7" "numpy<1.21" obspy pytest fortran-compiler
conda activate telews
pip install telewavesim

I started a branch scikit that repackages Telewavesim to build using the sciki-build-core back-end, but I am struggling with how to link the LAPACK libraries. Any hint is appreciated!
