installation failed for Apple Silicon (MacOS M1/M2), with potential solution

[yhsong1013]

Hi pydem team,

I am a MacOS user and failed to install pydem on my Apple Silicon machine with the standard method.
I found that the compile_args.append("-march=x86-64") is hard coded in setup.py, thus any installation from pip or conda would fall. I worked around it by clone the source, modify setup, and install from the source could solve. Just to paste what I did here for your consideration:

1. Prepare dependencies with conda (optional)

I use conda for env management, but this step is totally optional. I follow your instruction of the dependencies

conda create -n pydem python=3.11
conda activate pydem
conda install numpy cython pip wheel setuptools

2. Clone the pyDEM Repository

git clone https://github.com/creare-com/pydem.git
cd pydem

3. Modify setup.py for Apple Silicon Compatibility

In setup.py around line 32, modify to:

compile_args.append("-std=c++17")    # making sure compiler is consistent
import platform
arch = platform.machine()
if arch == "arm64" or arch == "aarch64":
    compile_args.append("-march=armv8-a") # making sure 

After that, I just install from the source code. pip install .

Hello, I'm also encountering this issue, would be great to be able to use this package on native apple silicon! The above fix did not work for me, likely due to some clang version issues on my end. If the developers want, I can try to dig into this and provide a pull request.
