Need a ".whl" to install.

[JuarezBfi]

Hello, I'm trying to install the library, but I can't. The 'pip' installation in python 3.11 cannot build the wheel for the library. But I'm sure I can install the module with a '.whl' file.

I guess this is to do with the distutils -> setuptools switch that's needed for python 3.11 - I've been working on that in the 'dev' branch. Perhaps if you try 'pip install -e .' for the dev branch it might work? Sorry, I haven't made a new release on PyPI with these changes in yet. Which platform / OS are you using?

I've made a new release that's now on PyPI (v0.11.9) - hopefully this should fix this issue.

Also on python 3.10. It's a blocker because we're trying to build Docker images that have some software that have astLib as a requirement.

Failed to build astLib

It seems to be a problem with gcc not finding the right files:

Ok - I'm not having this problem (running Ubuntu variant with Python 3.10.12) - what platform / OS are you using?

[Joshuaalbert]

Try building this Dockerfile:

FROM python:3.10.8


RUN apt-get update && \
    apt-get install -y vim less git htop feh build-essential wget && \
    rm -rf /var/lib/apt/lists/*


WORKDIR /dsa/code

COPY requirements.txt .

RUN pip install -r requirements.txt

With this requirements.txt:

quartical
astropy
numpy<1.24.0
scipy
astLib
python-casacore
future
astro-kittens
matplotlib
jupyter

docker --version is Docker version 24.0.6, build ed223bc
