libmimalloc-sys v0.1.39->v0.1.41 introduced build failure on some platforms

[hombit]

I use mimalloc in one of my projects to build Rust-powered Python packages. I noticed that after the recent update from 0.1.39 to 0.1.41, the libmimalloc-sys build has failed with the following error:

cargo:warning=In file included from c_src/mimalloc/src/alloc.c:14,
  cargo:warning=                 from c_src/mimalloc/src/static.c:23:

  cargo:warning=c_src/mimalloc/include/mimalloc/prim.h:240:21: error: ‘__builtin_thread_pointer’ is not supported on this target
  cargo:warning=  240 |   return (uintptr_t)__builtin_thread_pointer();

This can be reproduced with Docker, create Dockerfile and run

docker build -t build_libmimalloc-sys .
docker run --rm build_libmimalloc-sys

FROM quay.io/pypa/manylinux2014_x86_64

# Update Certificates
RUN yum install -y openssl-devel

# Install Rust
RUN curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain stable -y
ENV PATH="${PATH}:/root/.cargo/bin"

# Create a project
RUN cargo init /project
WORKDIR /project
RUN cargo add libmimalloc-sys

# Build the project
CMD ["cargo", "build"]

It’s even more confusing that my CI builds pass for all MUSL-based and all ARM64 images, but not for GLIBC PPC64LE: https://github.com/light-curve/light-curve-python/actions/runs/8793140128

Same issue here, I do not know what caused it

Seems to be an upstream issue. This check seems to pass in your case but __builtin_thread_pointer is not available on that target.

Should I file an issue for the original C library?

[octavonce]

Yes

I got it to work by changing the distro I am using for my containers. I switched from debian bullseye to ubuntu latest (LTS). However, I did not investigate further.

Hitting the same issue here on a centos7 based container (quay.io/pypa/manylinux2014_x86_64). Unfortunately we're stuck with this container because we need to support a glibc 2.17 compatible binary.

Please check the latest release

Thank you, it is fixed now!
