tkinter on redhat (and testing of tkinter) #5

Open chrisjsewell opened 3 years ago

chrisjsewell commented 3 years ago

for Ubunut, there is a python3.x-tk package available for 3.6-3.8 (via deadsnakes repo).

However, this is not the case for base yum in redhat:

Current;y I a'm "falling back" to just install python3-tkinter if python3x-tkinter fails, but I don't know if that will actually work.

Ideally we would also test that tkinter is working on all distributions. This is tricky though, because really you need a display:

Perhaps using xvfb: https://serverdiary.com/linux/how-to-install-xvfb-and-create-systemd-xvfb-service-on-centos-7-8-or-rhel-7-8/

Ah so actually on Ubuntu it is defaulting to python3-tk which installs for all python 3.6-3.8: https://stackoverflow.com/questions/59725147/install-tkinter-for-python-3-7-3-in-ubuntu-18-04

# dpkg-query -L python3-tk
