[yocto] Cannot load Gtk3: Could not lookup GType

[Maciej Pijanowski]

Hello,
I'm trying to port custom perl application from Debian into Yocto (morty).
I'm stuck at testing Gtk3 perl module. It looks to me that all necessary
components are already there. It looks to me that the issue is rather 
related
to Gtk3 or it's dependencies, rather than perl and it's modules. What do 
you think?
I'm certainly not a Gtk expert. Do you have any idea how could I further 
debug
this? Any hints what could be the issue?

```

```

I'm running in qemu right now. My setup is:

* Perl verion: This is perl 5, version 22, subversion 1 (v5.22.1) built 
for x86_64-linux
* Relevant libraries:
libcairo-gobject.so.2.11400.6
libcairo.so.2.11400.6
libgtk-3.so.0
libatk-1.0.so.0.22009.1
libgobject-2.0.so.0.4902.0
libpangocairo-1.0.so.0.4000.1
libgdk-3.so.0.1800.5
libgdk_pixbuf-2.0.so.0.3200.3

* Relevant perl modules:
Cairo/GObject.pm
Cairo.pm
Glib/Object/Introspection.pm
Glib.pm

Thanks for any feedback
