Hi all,<br><br>Can I ask your advice on something?<br><br>When my friend runs the following snippet on his Macbook, it crashes.<br><br> require 'cairo'<br> require 'pango'<br> require 'gtk2'<br> win = Gtk::Window.new<br>
win.set_default_size 300, 300<br> canvas = Gtk::Layout.new<br> surface = Cairo::ImageSurface.new Cairo::FORMAT_ARGB32, 300, 300<br> context = Cairo::Context.new surface<br> layout = context.create_pango_layout<br> layout.text = 'hello world'<br>
context.show_pango_layout layout<br> context.show_page<br> surface.write_to_png 'temp.png'<br> img = Gtk::Image.new 'temp.png'<br> canvas.put img, 50, 50<br> win.add canvas<br> win.show_all<br> Gtk.main<br>
<br>But on my Windows 7, it works well.<br>He is using Macbook with Lion, Xcode 4.1 and rvm.<br>ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]<br>Ruby/GNOME2 v1.1.2<br><br>More information is here: <a href="http://pastie.org/3230151">http://pastie.org/3230151</a><br>
