Python 3.9 is not supported under some conditions about basilisk

[patkenneally]

@Mark2000 Can we please hold off on changing any documentation, and associated automation? I'm fairly confident that Basilisk works on Python 3.9 with Ubuntu 20.04 and 22.04. Give me a week or two to get back to you with the confirmation (hoping for sooner).

People have reported issues compiling with both Ubuntu 22.04 (as opposed to 20.04) and Python 3.9 (as opposed to 3.10+). Please let us know what combination of versions works for you so we can update the requirements.

@Mark2000 Thank you! I found the solution you wrote for windows. but also worked for me. https://github.com/AVSLab/basilisk/issues/695#issuecomment-2118824577. Then change my combination of versions Python 3.10.4 conan 1.59.0 swig 4.2.1 using anaconda also worked. Hope you update the requirements in the web document.

@Daniel-Huff thanks for bringing this up. We'll keep this issue open until the docs have been updated to reflect Python 3.9 deprecation or until we restore 3.9 support.

[Daniel-Huff]

Really thank you. This issue can be closed

[Mark2000]

Yeah, I’m hoping to replicate the conditions I ran into that were fixed by moving from 3.9->3.10 to see if the issue can be narrowed down more.

I agree with @patkenneally regarding Python 3.9 and Ubuntu 20.04, that is the combination that our current CI build uses. What I would like to do is expand our CI testing to begin to test against multiple versions of python such as at least 3.9, 3.10 and 3.11. Has anyone here tried 3.12 yet? I'm still on 3.11.

If it turns out there are particular combinations of Ubuntu and Python challenges, we can look at updating the documentation if that makes sense. Right now I feel we need more info on this. I would like to retain python 3.9 compatibility unless there is a clear technical reason to drop it.
