We head some headache, as the example GTK4 for Graphical User Interfaces stopped working with GTK 4.10. Actually, they released Nim 1.6.12 some days ago, so first guess was a compiler issue. Running that example, gives an empty file area and a lot of
(filechooserdialog:11122): Gtk-CRITICAL **: 21:59:32.837: Error building template for list item: .:0:0 Invalid object type 'GtkFileChooserCell'
Finally we discovered, that instead of the standard Nim compile command “nim c file.nim” we now have to use something like
nim c --passL="-lgtk-4" fc.nim
The “–passL=”-lgtk-4" makes it working. I wonder if other language bindings are concerned as well, and what exactly has to be included by the linker.
