I guess python3-config from sysroot-cross should be used, but there is only python3.13-config. So I wonder whether A) there is a symlink (or copy) missing: sysroot-cross/usr/bin/python3-config -> python3.13-config B) libgpiod's configure.ac has to be patched: -python3-config +python3.13-config Markus
