Gtkmm-4.0 AppImage

hi new bee here
im trying to create AppImage for my gtkmm4 application unfortunately designated machine with operating sistem Linux Neon KDE keeps saying

/usr/bin/grunf: symbol lookup error: /tmp/.mount_grunf.3PiuG4/usr/lib/libgiomm-2.68.so.1: undefined symbol: g_file_make_symbolic_link_async

i copied designated files ending so.0 without links that are pointing to shared library files.

g_file_make_symbolic_link_async() is new in glib 2.73.2.
Gio::File::make_symbolic_link_async() is new in glibmm 2.73.2.
Which releases have you installed?

i see …thank you… I’ve must slipped and use some file from different machine then
