Compact GTK 4 app on Windows, where to put icons

Platform Core

I decided to try creating a compact application with GTK 4 on windows. By compact, I mean non-installable. I installed GTK 4 via MSYS2, removed msys/bin from the environment variables, and added the necessary dlls to the same exe folder, here is the list:

Now running the exe I get the following log:

(process:3728): Gdk-CRITICAL **: 01:29:28.222: gdk_display_get_clipboard: assertion 'GDK_IS_DISPLAY (display)' failed

So I copied Adwaita folder from msys2, but I dont know how I need to put it near exe so exe can find it.
ls in Adwaita folder:

Youā€™re missing the PNG loader for gdk-pixbuf.

I got a similar error from gdk-pixbuf for SVG, while running an app ( SVG app icon image ) in docker.

Iā€™m assuming gdk-pixbuf should have a ā€œRequires:ā€ build time dependency and ā€œRecommends:ā€ run time dependency on all supported image formats, and the distro got the runtime dependency wrong ?

Thanks!

I added all libpixbufloader-*.dll from C:\msys64\mingw64\lib\gdk-pixbuf-2.0\2.10.0\loaders but have same error. libpixbufloader-png.dll was one of them.

Did you generate the loaders.cache file using gdk-pixbuf-query-loaders?

Alternatively, you can rebuild gdk-pixbuf with all the loaders built in.
