    Thanks for reporting the issue. Can you also let us know the numpy version and which compiler and version you are using?

    The bx_python-0.12.0.tar.gz sdist from PyPI contains C files built with Cython and numpy 2.0, so it should be possible to install it with numpy >=1.25 (the oldest numpy release to support Python 3.9).
    If you are using an older numpy, gcc will consider -Wimplicit-function-declaration and -Wint-conversion as warnings and not errors and install bx-python 0.12.0 fine, so I suppose you are using clang as compiler.
    A workaround for your case should be to unpack the bx_python-0.12.0.tar.gz sdist, then:

    $ cd bx_python-0.12.0/
    $ python3 setup.py build_ext --force
    $ python3 -m pip install .
