Unable to build ruff on aarch64 alpine docker

[matejsp]

I am getting undefined reference to `getauxval' using ruff 0.2.2 and rust 1.75.0

I saw mentioning this issue very often and in rust-lang/rust#89626 there is potencial workaround:
CFLAGS=-mno-outline-atomics but I don't know if same solution applies to ruff and where to put it.

That's interesting. It's not clear to me why you run into this. We do create musl builds in CI and that works fine, strange.

Could you share some more details about your setup? That would help us to reproduce the issue.
What's your docker image? What commands are you running?

I made it working by adding: export CFLAGS=-mno-outline-atomics before calling wheel

will try to reproduce it at home after work because our corpo firewall is messing with ssl certificate ...

docker run -it alpine bash
apk add python3-dev py3-pip bash maturin
wget https://files.pythonhosted.org/packages/70/06/b2e9ee5f17dab59476fcb6cc6fdd268e8340d95b7dfc760ed93f4243f16f/ruff-0.2.2.tar.gz
wget --no-check-certificate https://static.rust-lang.org/dist/rust-1.75.0-$(uname -m)-unknown-linux-musl.tar.gz
tar -xzf rust-1.75.0-$(uname -m)-unknown-linux-musl.tar.gz

export CFLAGS=-mno-outline-atomics
pip install wheel --break-system-packages
pip wheel ruff-0.2.2.tar.gz

@matejsp did you figure more out here / is there anything actionable for us to do?

Closing for now...
