= About the Ruby-GNOME2 project

As a reminder, and for those that didn’t know, the Ruby-GNOME2 project
is a set of bindings for the GNOME 2.x and 3.x libraries to use from
Ruby 2.1, 2.2 and 2.3.

The Ruby-GNOME2 project provides the following gems:

atk cairo-gobject
clutter clutter-gstreamer
clutter-gtk gdk_pixbuf2
gdk3 gio2
glib2 gobject-introspection
gstreamer gtk2
gtk3 gtksourceview2
gtksourceview3 gvlc
pango poppler
rsvg2 vte
vte3 webkit-gtk
webkit2-gtk webkit-gtk2

Since the version 3.0.0, the Ruby-GNOME2 gems are based on the
gobject-instropection whenever it is possible. The platforms supported
are Linux, Windows and OS X.

In order to install a gem (gtk3 for example) just do :

  gem install gtk3

= About GTK+

from http://www.gtk.org/

GTK+ is a highly usable, feature rich toolkit for creating
graphical user interfaces which boasts cross platform
compatibility and an easy to use API. GTK+ it is written
in C, but has bindings to many other popular programming
languages such as C++, Python and C# among others. GTK+ is
licensed under the GNU LGPL 2.1 allowing development of
both free and proprietary software with GTK+ without any
license fees or royalties.

= About GNOME

from http://www.gnome.org/about/

The GNOME project provides two things: The GNOME desktop
environment, an intuitive and attractive desktop for
users, and the GNOME development platform, an extensive
framework for building applications that integrate into
the rest of the desktop.

Some say that this kind of error (Gem::RemoteFetcher::UnknownHostError)
are related to a problem of internet connection other say that they were
able to solve this kind of problem with the following command:

gem update --system

Could you try it?

Before going forward, are you using ruby v2.0.0?

We have dropped the support for this version. Could you update your ruby
version?

ruby -v
ruby 2.0.0p0 (2013-02-24) [i386-mingw32]

Oups.

==

installing ruby 2.3
All works find, except:

A)

In e simple application showing a analog clock in a Drawing widget,
(chrome(false) for windows), I got on mouse button press :

gadget_clock.rb
Assertion failed!

Program: D:\usr\Ruby\Ruby23\bin\ruby.exe
File: cairo-surface.c, Line 956

Expression: CAIRO_REFERENCE_COUNT_HAS_REFERENCE (&surface->ref_count)

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application’s support team for more information.

I have many other application which use sames commands for drawing some
vector. All them works find, except those which modify chrome() on
button press in drawing widget (gadget* in Ruiby/samples).

B)
the bar title (windows 10) show strange icon for iconify/full-display
button.
(see attached png)

Thank you for all this work !!!
