私は Ubuntu 10.04 を使用しており、このサイトWxRubyWikiからコピーして貼り付けた WxRuby の例を実行しようとしています。ネットで調べてみたのですが、似たようなものは見つかりませんでした...
このエラーが発生しています...
Gtk:ERROR:/build/buildd/gtk+2.0-2.20.1/gtk/gtkwindow.c:6789:IA__gtk_window_present_with_time: assertion failed: (widget->window != NULL)
Aborted
これらは私が使用しているバージョンです...
ruby -v
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]
gem list
...
wxruby (2.0.1 x86-linux)
...
そして、これは私が実行しようとしているコードです...
