Do you have gtk3 installed on the system?

from gtkd.

Yes, I am using gnome 3.4.
I tested glade 3.12 and the previewer works.

from gtkd.

if it can help, this is gdb trace:

I'm setting up an 32bits vm to take closer look at this, there seems to be an bug in the name_override function.

from gtkd.

Same problem on LMDE 64-bit. No problem running it on Ubuntu 12.04 and 12.10 64-bit

from gtkd.

thanks for trying :)
for information, i'm on debian wheezy up to date.

from gtkd.

I finally found why:
in gtkc/glibtypes.d (line 88) , i set _utfPostfix = "" (it was to "_utf8" for d2/linux)
and to re-compile, gtkc/glib.o must be clean too (cause of mixin, i guess)

I took a look to my libgtk-3 src and g_module_open doesn't have "_utf8" suffix.
maybe a problem of libgtk-3-0 version ?
my libgtk-3 : 3.4.2-4 with libgtk-3.so.0.400.2

from gtkd.

Thanks

_utfPostfix should indeed be an empty string on linux, as the utf8 less functions are macros in the windows version of gtk.
