Support Linux ARM64

[kratman]

Support ARM64 platform, probably through the scikit build (#7)

[agriyakhetarpal]

Could you please rename the issue to specifically say Linux/Windows arm64, since we have macOS arm64 already?

scikit-build-core is only a build backend, so it would only make it easier for cross-compiling but wouldn't help with the actual compilation. We can cross-compile without it, too, or use QEMU – setuptools works equally well. Q1/Q2 2025 is the expected timeline for Arm runners for native compilation: github/roadmap#970

Yeah I was just putting this as a reminder really. I know that we will lack runners for a while. I can use docker for testing ARM64 builds, when I use linux docker on my mac it tries to use Linux ARM64

it seems available now, the runners labels are:
– ubuntu-24.04-arm
– ubuntu-22.04-arm

btw, the readme for linux installing missing apt-get install:

sudo apt-get libopenblas-dev gcc gfortran make g++ build-essential
pip install cmake casadi setuptools wheel
python install_KLU_Sundials.py
pip install .

Thanks, @chuckliu1979 – this is already underway and @kratman is progressing on it in #28.
