问题
I migrated my program built with gtk+3.0 from linux to Mac OS X(10.6.8).
And I compiled the program without errors.
However, after I started the program and I chose to open a file, the terminal shows following message.
GLib-GIO-CRITICAL **: Settings schema 'org.gtk.Settings.FileChooser' is not installed
Then, the program ends with Segmentation fault.
How to solve it? Thanks for any helps.
回答1:
Seems you're not the one having this problem, and it also happens on Windows on MinGW. Luckily, that person gave a solution:
The thing, as it seems as I was running the test-widget example (that I built with gtksourceview-3.0.0 using MSVC), was that I need to compile the org.gtk.Settings.FileChooser.gschema.xml file (from GTK+-3.x, under $(srcroot)/gtk) with the glib-compile-schemas utility that is from GLib, which will generate gschemas.compiled in the same folder.
After that, place that gschemas.compiled file in the this folder: $(parent_folder_of_the_gtk3_dll)\share\glib-2.0\schemas and one will be set to use the gtkfilechooser without the puzzling
[GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser' is not installed] error.
I will add to my GLib project files to compile the glib-compile-schemas utility and add to my GTK+-3.x project files to compile the the org.gtk.Settings.FileChooser.gschema.xml shortly.

I ran in to this problem with a program that I crosscompiled with mingw for windows, the solutions is to run glib-compile-schemas [path to org.gtk.Settings.FileChooser.gschema] in my case was that file in ./share/glib-2.0/schemas.It will generate gschemas.compiled, that is the file FileChooser is looking for.
