This is the code causing the problem:

class myInputDialog : Dialog
...
this()
{
    super("Please enter file location...", this, GtkDialogFlags.MODAL | GtkDialogFlags.DESTROY_WITH_PARENT, [StockID.OK], [GtkResponseType.OK]);
    with (addButton(StockID.OPEN, GtkResponseType.NONE))
    {
        setLabel("_Find file");
        addOnClicked(&findFile);
    }
    addButton(StockID.CANCEL, GtkResponseType.CANCEL);
...
    Entry fileLocInput = new Entry();
...
}

void findFile(Button but)
{
    FileChooserDialog fileWindow = new FileChooserDialog("Use File...", this, GtkFileChooserAction.OPEN, ["Open", "Cancel"], [GtkResponseType.ACCEPT, GtkResponseType.CANCEL]);
    fileWindow.run();
    writeln(fileWindow.getFilename());
}

It produces the error "GLib-GIO-ERROR **: No GSettings schemas are installed on the system". The command prompt window in the background says "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information." and then appears to segfault.

Windows 7 x64, DMD v2.060, GTK+ Runtime 3.4.2, GtkD 2.0

Anyone know why this is happening? If I comment out the addOnClicked(&findFile) bit, findFile never runs and the problem doesn't happen, except I can't browse for files.

Thanks,

Josh

It looks like the Gtk Runtime wasn't installed properly, you could try manualy generating the GSettings schemas by running:


C:\Program Files\Gtk-Runtime\bin\glib-compile-schemas.exe C:\Program Files\Gtk-Runtime\share\glib-2.0\schemas\

The schemas directory should contain a bunch of xml files that will need to be compiled. The paths may vary depemding on where the Gtk runtime was installed.

Thanks Mike. But I already have these files in the schemas folder. Do I have to still compile them again?

Sorry, I misread, I thought the xml files were the compiled bits. When I ran glib-compile-schemas.exe, I get the following:

warning: Schema 'org.gnome.system.proxy' has path '/system/proxy/'.  Paths starting with '/apps/', '/desktop/' or '/system/' are deprecated.
warning: Schema 'org.gnome.system.proxy.http' has path '/system/proxy/http/'.  Paths starting with '/apps/', '/desktop/' or '/system/' are deprecated.

Anything I should be worried about?

Thanks again,

That are the same warnings i get, does the FileChooserDialog work properly after running glib-compile-schemas.exe ?

I'm not sure why its not working, could you try the 3.6 runtime?

Uninstalled GTK 3.4.2 and GtkD 2.0, installed GTK 3.6.1 64 bit, tried building GtkD 2.1.1, and got this:

C:\D\GtkD\build>build @gtkD.brf
..\src\glib\Spawn.d(244): Error: undefined identifier fdopen, did you mean function fopen?
..\src\glib\Spawn.d(245): Error: undefined identifier fdopen, did you mean function fopen?
..\src\glib\Spawn.d(246): Error: undefined identifier fdopen, did you mean function fopen?

Do I just rename the fdopen to fopen in Spawn.d?

Thanks,
Josh

For 32bits Windows fdopen was added to druntime with dmd 2.061.
So you are probably using an older compiler, if thats the case you could remove the "version(Win64)" from src/gtkc/glibtypes.d line 111.

Ah, thank you, I didn't realise there was a new compiler. Installed that, built GtkD, compiled my program fine, ran it, and it said:

The image file C:\Program Files\Gtk-Runtime\bin\libgdk-3-0.dll is valid, but is for a machine type other than the current machine. Select OK to continue, or CANCEL to fail the DLL load.

and

The image file C:\Program Files\Gtk-Runtime\bin\libgtk-3-0.dll is valid, but is for a machine type other than the current machine. Select OK to continue, or CANCEL to fail the DLL load.

and then has an access violation. Am I right in assuming this is a 64 bit problem? I thought dmd now had Windows 64 bit support?
