"symbol __cxa_thread_atexit_impl, version GLIBC_2.18 not defined" running maturin 0.8.3 wheel in manylinux2014_aarch64

[JEnoch]

Please provide the following information:

• Your python version (python -V): 3.8.6
• Your pip version (pip -V): 20.2.3
  • If this isn't the latest pip version, have you checked using the latest pip version?
    Yes: same issue with pip 20.2.4
• The version of the bindings you're using, if any (e.g. pyo3, rust-cpython or cffi):
  None, I just run maturin --help
• Does cargo build work?
  Not relevant
• If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?
  Not on windows

Please list the exact steps required to reproduce your error with all command output and if possible with a repository:

• I install maturin 0.8.3 in the latest manylinux2014_aarch64 (sha256: 576ffd8ecbda) and run maturin --help :

docker run --init -it --rm quay.io/pypa/manylinux2014_aarch64:latest /bin/bash -c "/opt/python/cp38-cp38/bin/pip install maturin && /opt/python/cp38-cp38/bin/maturin --version"

The result output is:

The issue looks similar to the one described in https://stackoverflow.com/questions/39744926/how-can-i-compile-a-rust-program-so-it-doesnt-use-cxa-thread-atexit-impl .
Which Rust toolchain was used to build the maturin-0.8.3-py3-none-manylinux2014_aarch64.whl ?

[JEnoch]

As a workaround, I created a Docker image based on manylinux2014_aarch64 and including a compiled version of maturin 0.8.3: https://hub.docker.com/repository/docker/adlinktech/manylinux2014-aarch64-rust-nightly
See its Dockerfile.

The aarch64 builder was building a wheel that was not actually manywheel compliant, as it was built with the glibc toolchain. If tried to fix this by building a musl binary as I already do for the other platforms, but now I'm getting errors when compiling dependencies (https://cloud.drone.io/PyO3/maturin/234/1/2), so publishing a fixed wheel is blocked on figuring out ci.

[JEnoch]

I was able to compile maturin 0.9.3-alpha.3 in a Docker python:3.8-buster image after installing the aarch64 musl toolchain and applying this workaround for rust-lang/compiler-builtins#201 issue: rust-lang/rust#46651 (comment)

Thus I think adding something like this to your .drone.yml commands should be good enough:

wget http://musl.cc/aarch64-linux-musl-cross.tgz
tar xzf aarch64-linux-musl-cross.tgz -C /opt --strip-components=1
export PATH=$PATH:/opt/bin
echo '[target.aarch64-unknown-linux-musl]' >> ~/.cargo/config
echo 'linker = "aarch64-linux-musl-gcc"' >> ~/.cargo/config
echo 'rustflags = [ "-C", "target-feature=+crt-static", "-C", "link-arg=-lgcc" ]' >> ~/.cargo/config

Unfortunately, this still fails at bzip-sys: https://cloud.drone.io/PyO3/maturin/270/1/2

Config:

- name: publish
  image: python:3.8-buster
  environment:
    PATH: "/root/.local/bin:/root/.cargo/bin:/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

@JEnoch Can you give #422 a try?

[JEnoch]

@messense Yes, I confirm the wheel you refer in #422 works like a charm in quay.io/pypa/manylinux2014_aarch64:latest.
Many thanks!
