I am trying to get PySimpleGUI running on an RPi4 using meta-raspberrypi with hardknott.
I have created a recipe for PySimpleGUI and added the following to my local.conf:
PACKAGECONFIG_pn-python3 = “tk”
IMAGE_INSTALL_append = " python3 python3-modules python3-pysimplegui tk"
However, the tkinter module fails to load, reporting “No module named _tkinter”, with a note above saying that Python may not be configured for Tk.
Looking on the target, /usr/lib/libtk.8.so is present.
It looks as if there is something else I need to do to get Python to build correctly, but I’m out of ideas ;-)
You need to add “tk” to the package config for python3
Add the following to your distro|site|local.conf (or a python3_%.bbappend)
PACKAGECONFIG:append:pn-python3 = “ tk”
( replace : with _ if you are on old release that doesn’t support the new override syntax)
(This assumes you have meta-oe in your bblayers.conf so you can build tk, which it sounds like you do)
This is because the _tkinter .so built by python3 is dynamically loaded only if present

I’ve found a few bits on the internet that seem related, but they haven’t helped me get things going:

Any pointers on where to look would be appreciated.
