Hey there,
I’m trying to create a hello world like app on win10 with Glade 3.38.2 but with a Gtk::Image
Since then I’m experiencing crashs or errors:
Gtk-WARNING **: 21:40:26.702: Could not load a pixbuf from /org/gtk/libgtk/icons/16x16/status/image-missing.png.This may indicate that pixbuf loaders or the mime database could not be found.

Gtk:ERROR:…/gtk±3.24.25/gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /org/gtk/libgtk/icons/16x16/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3) Bail out! Gtk:ERROR:…/gtk±3.24.25/gtk/gtkiconhelper.c:494:ensure_surface_for_g
icon: assertion failed (error == NULL): Failed to load /org/gtk/libgtk/icons/16x16/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)
I’m using C++ and the gtkmm bindings and for compilation mingw64 with:
g++ pkg-config --cflags gtkmm-3.0 -o s s.cpp pkg-config --libs gtkmm-3.0
But when executing the app I’m using the normal cmd from the executing directory, which worked if catched or without image fine. The idea is to compile to an exe which can run as standalone therefore all linked dll (ldd s.exe) from mingw were copied into the executing directory
tried:
- After the first few crashs I tried to add gdk-pixbuf-2.0 to the lib and includes but without result.
- Also I specified the Image in the beginning in Glade but changed to load via
auto image = Gdk::Pixbuf::create_from_file(“z.jpg”);
Glib::RefPtrGtk::Image::cast_dynamic(b->get_object(“image”))->set(image);
but also unsuccessful - I hoped to get more infos when catching the error and printing with what() but just prints
PixbufError: Couldn - I tried out of curiosity what happens if I select a Stock Image see Error below
Error with Stock Img

Qs
- I have read that it could depend on the mime cache or sth like that and tried
$ update-mime-database /usr/share
Failed to rename B:/msys64/usr/share/icons.new as B:/msys64/usr/share/icons: File exists
But I’m not sure that this is the cause, and would it be possible to write a custom path so that it could be loaded out of the project/executing directory ?
- In Glade in the Preview the Image is drawn fine, so i don’t think the mime cache or pixbuf general should be the problem (hypothetically )
- general ideas or solutions
V
- Win 10
- Mingw64
- Glade 3 38.2
- GTK3 with gtkmm
Thank you
