CPHD Reader for build

[RyanUmby]

I'm attempting to build six to read cphd files. I followed the instructions for building and created the wheel. Most imports work, however, the cphd module does not load.

I get the following error:

ImportError: /usr/local/lib/python3.10/dist-packages/pysix/_cphd.cpython-310-x86_64-linux-gnu.so: undefined symbol: _ZN10numpyutils12toNumpyArrayEmmiPKv

I've included a dockerfile that recreates the error

FROM ubuntu:22.04
  
  RUN apt-get update \
      && apt-get install \
        build-essential -y \
        cmake \
        git \
        curl \
        python3.10 \
        pip

  # Download the six library
  RUN pip install numpy \
    && git clone https://github.com/ngageoint/six-library.git \
    && ln -sf /usr/local/lib/python3.10/dist-packages/numpy/core/include/numpy/ /usr/include/numpy

  # Build and install the python bindings
  RUN cd six-library \ 
    && /usr/bin/python3 waf configure --prefix=install \
    && /usr/bin/python3 waf install \
    && /usr/bin/python3 waf makewheel \
    && pip install install/bin/pysix-3.0.0-cp310-cp310-linux_x86_64.whl

any help is appreciated.

For clarity, the imports into python

from pysix import cphd

throws the above error
