Description

I'm on macOS and ran into this issue:

rustup update
git clone https://github.com/rochacbruno/rust-python-example
cd rust-python-example
make compile-rust

then I was greeted by this:

which after a lot of scrolling ended in this:

error: linking with `cc` failed: exit code: 1

  = note: "cc" "-m64" "-L" …

…

          ld: symbol(s) not found for architecture x86_64
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

What am I missing?

Contributor guide

Research direction
Ensure Python development headers are installed (e.g., `brew install python`). For macOS, set the linker search path using environment variables like `LIBRARY PATH` or `DYLD LIBRARY PATH`. Verify that the crates matching the Python version are installed correctly.
