Re: [fltk/fltk] [fltk 1.4.x/Linux] application invoking native filechooser crashes under linux if fltk built with --enable-localpng (#232) Albrecht Schlosser May 28, 2021  
 

I built a docker image with Scientific Linux and I can now reproduce the crash with this docker image:

(native-filechooser:1): GdkPixbuf-WARNING **: 13:34:51.006: Bug! loader 'png' didn't set an error on failure

(native-filechooser:1): Gtk-WARNING **: 13:34:51.006: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

(native-filechooser:1): GdkPixbuf-WARNING **: 13:34:51.006: Bug! loader 'png' didn't set an error on failure
**
Gtk:ERROR:gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Adwaita/16x16/status/image-missing.png: Internal error: Image loader module ?png? failed to complete an operation, but didn?t give a reason for the failure (gdk-pixbuf-error-quark, 5)

FWIW: My docker build script 'Dockerfile' (rename to Dockerfile if you like to try it).

Nice "side effect": the Dockerfile is a short "HowTo install FLTK on Sci Linux" -- of course not in the same '/fltk' folder and not as root, but it list all required packages (but not some optional ones).
