Error installing with pip using Python 3.12

Hi, I'm getting the following error when installing with pip using python 3.12:

Is python 3.12 not supported by the program yet? If this is the case, are there any plans to support it in the future? Thank you.

Im getting the same error and I'm using python 3.10

Hey @AndreiVernon, indeed the package provided by pypi does not support python 3.12 atm, that is because wxPython (the gui framework, displaycal heavily relies on, does not support python-3.12 properly atm). However you can just use the "develop" branch and should be able to run displaycal with python-3.12 if you don't mind displaycal not exiting properly. You can read about it here: https://github.com/wxWidgets/Phoenix/issues/2455 @ColorfanXP are you sure you getting the exact same error?

@AndreiVernon DisplayCAL + Python 3.12 under Windows will not install at all. Try using Python 3.11, but I fixed Windows version just recently, you need to build from source, you can follow the Menual Setup (Windows) section...

or just wait until I release 3.9.13 around one or two weeks...

in gentoo, wxpython is available now with python 3.12 My gentoo box can hardly install any software <python 3.12 (or would need a lot of geek fiddeling, wich I cannot spend the time on)

I would happily see displaycall-py get upgraded accordingly

[p5k369]

Hey @AxelG-DE if you refer to the gentoo ebuild you have to contact the maintainer or build it yourself. https://packages.gentoo.org/packages/media-gfx/displaycal-py3 You won't find any distribution specific packages in this repository.

However, on Gentoo you can run displaycal with Python 3.11 or 3.12 without any problems in a virtual environment. Just follow the guide here: https://github.com/eoyilmaz/displaycal-py3/blob/develop/docs/install_instructions_linux.md#build-from-source-manual

My gentoo box can hardly install any software <python 3.12 (or would need a lot of geek fiddeling, wich I cannot spend the time on)

As I already wrote, you don't have to do that on gentoo if you are running the develop branch of displaycal because that one alreasy runs with python-3.12. But even if you don't, it is no problem at all to have two or more python versions installed on gentoo. In fact, that is exactly what I am doing. You can do that without any changes via virtualenv or, and that is the way that I prefer it, just install eselect-python and switch your interpreter on the fly. That way you literally can copy the commands from the manual setup.

[eoyilmaz]

closing this as the original issue related to Windows + Python 3.12 is a no no for now...

@AxelG-DE if you still require, please open a new issue related to Gentoo... which most probably going to be Gentoo maintainers business anyway... But, incase we might have introduced a bug that is preventing DisplayCAL to work properly under Gentoo, again, please open a Gentoo specific issue.

[AxelG-DE]

Oh sorry ladies and gentlemen, I forgot to report back here... The maintainer has updated the ebuild, where I thought it was an upstream thing.

All fine on my end now. Thanks all
