The reverted commit causes regression when ldconfig not in
DISTRO_FEATURES, before, without ldconfig in DISTRO_FEATURES,
ctypes.util.find_library(name) can find the lib if it is installed,

Hello Changqing Li,

Did I understand correctly that gtk+3 was found before, indent of ldconfig
was in der DISTRO_FEATURES? But after the change, if fails.

Where is libgdk installed? In /usr/lib or somewhere else?

Hi,

libgtk is under /usr/lib. See:

root@qemux86-64:~# ldconfig -p | grep gtk-3 

libgtk-3.so.0 (libc6,x86-64) => /usr/lib/libgtk-3.so.0 

root@qemux86-64:~# python3 

Python 3.13.2 (main, Feb 4 2025, 14:51:09) [GCC 14.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. 

>>> from ctypes.util import find_library 

>>> find_library('gtk-3')

 'libgtk-3.so.0'

For the case that ldconfig is NOT in DISTRO_FEATURES, gtk+3 can be found. After commit "python3-ctypes: depend on ldconfig only if distro-feature set" is merged,

ldconfig is not installed, so ctypes.util.find_library cannot found gtk+3.

Bye, Jörg
