My guess is that's related to the path on ubuntu being /usr/x86_64-w64-mingw32/lib/libpthread.a while on fedora it's /usr/x86_64-w64-mingw32/sys-root/mingw/lib/libpthread.a although running RUSTFLAGS="-L /usr/x86_64-w64-mingw32/sys-root/mingw/lib" cargo build (i also tried all subpaths) did not help either

Here is my test setup:

FROM ubuntu

RUN apt-get update && apt-get install -y \
    vim \
    curl \
    gcc \
    gcc-mingw-w64-x86-64 \
    && apt-get clean && rm -rf /var/lib/apt/lists/*

WORKDIR /app
ENV HOME=/home/rust
RUN groupadd -r -g 1000 rust \
    && useradd --no-log-init -r -g rust -u 1000 rust \
    && mkdir -p $HOME \
    && chown rust:rust $WORKDIR $HOME
USER rust
RUN curl https://sh.rustup.rs -sSf | sh -s -- -y
ENV PATH="$HOME/.cargo/bin:$PATH"
RUN rustup target add x86_64-pc-windows-gnu
RUN echo >>~/.cargo/config '[build]\ntarget = "x86_64-pc-windows-gnu"\n\n[target.x86_64-pc-windows-gnu]\nlinker = "x86_64-w64-mingw32-gcc"\nar = "x86_64-w64-mingw32-gcc-ar"'

FROM fedora

RUN dnf install -y \
    vim \
    gcc \
    mingw64-gcc \
  && dnf clean all

WORKDIR /app
ENV HOME=/home/rust
RUN groupadd -r -g 1000 rust \
    && useradd --no-log-init -r -g rust -u 1000 rust \
    && mkdir -p $HOME \
    && chown rust:rust $WORKDIR $HOME
USER rust
RUN curl https://sh.rustup.rs -sSf | sh -s -- -y
ENV PATH="$HOME/.cargo/bin:$PATH"

mkdir test
cd test
clippaste >Dockerfile # put above snippet in Dockerfile
docker build -t rust-test .
docker run --rm -it rust-test bash
USER=a cargo init --bin
cargo build # works with ubuntu but fails with fedora

I originally filed this here retep998/winapi-rs#527 because i thought it only happened when i added the winapi crate.

I found these similar issues #32859 #33465 #44787 but they seem not to be the same.

Have you tried installing "mingw64-winpthreads-static" that solved the problem for me.

[ssendev]

Thank you. It did for me too.
