2.0 release does not install on latest Fedora workstation (41) due to kivi

[makohoek]

Steps to reproduce:

1. Start a fresh fedora 41 installation in docker:

docker run -it fedora:41 /bin/bash

2. In the container, install all the dependencies:

[root@99a13277f8eb ~]# dnf install pip swig libusb gcc python-devel mesa-libGL-devel 

3. Install snagboot:

[root@99a13277f8eb ~]# pip install snagboot
[...] long logs and build failures

We see errors such:

     /tmp/pip-install-j9ti8x4b/kivy_0e9b85324a1749da9ae5d4e405dfadf9/kivy/_clock.c: In function ‘__Pyx_PyInt_As_long’:

Work-around on Fedora Workstation 41: install an older version of snagboot with:

$ pip install snagboot==1.3.0

Hello Mattijs, thanks for the detailed bug report!

This issue seems to occur when using python3.13. Kivy does not (yet?) provide prebuilt wheels for python3.13 on Linux. So pip tries to build the wheel from source, which fails because the Kivy source build requires specific versions of some dependencies (see kivy docs.

Once a newer version of Kivy with prebuilt wheels for Python3.13 is released to Pypi, I'll see if I can upgrade the dependency in Snagboot so that people don't encounter this issue.

For now, a possible workaround is to use Python3.12 instead:

dnf install python3.12-devel
#download and check integrity of get-pip script from https://bootstrap.pypa.io/get-pip.py
python3.12 get-pip.py
python3.12 -m pip install snagboot
