ruby-qt bindings - is somebody in charge of those?
in [Ruby]

From: Andrea Dallera on 21 May 2010 06:56 Hei Jan, I am using the version that comes with ubuntu - that's why I didn't really bother about versions. I will try to install the gem via rubygems for windows. I tried again, removing and reinstalling the packages with synaptic, and I still get the same segfaults. It is hard for me to provide you with exact examples that cause the issue, since I myself do not understand what exactly causes them and the code that generates the segfaults is built over the GUI framework. A very simple one would be to create a Qt::CalendarWidget and sending selectedDate=, nil to it, like this: require 'rubygems' require 'Qt4' app = Qt::Application.new([]) hello = Qt::CalendarWidget.new() hello.resize(200,200) hello.show() hello.selectedDate = nil #[BUG] Segmentation fault ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux] Again, this is just a trivial example and it's very easy to write a workaround for it: more nasty stuff happens when trying to add/remove items for a ListWidget for example. I will try to build a test case for that too. -- Andrea Dallera http://github.com/bolthar/freightrain http://usingimho.wordpress.com On Fri, 2010-05-21 at 12:33 +0200, Jan Pilz wrote: > Hi Andrea, > > yes please use shipped qtruby version which comes with Ubuntu, should > work. > I made gem for windows: > > http://rubyforge.org/frs/?group_id=181&release_id=42789 > > http://rubyforge.org/frs/download.php/69355/qtruby4-2.1.0-x86-mswin32.gem > > or do (on windows): > > gem install qtruby4 > > > > it includes all needed libraries.

[Note: parts of this message were removed to make it a legal post.] Hi Andrea, yes please use shipped qtruby version which comes with Ubuntu, should work. I made gem for windows: http://rubyforge.org/frs/?group_id=181&release_id=42789 http://rubyforge.org/frs/download.php/69355/qtruby4-2.1.0-x86-mswin32.gem or do (on windows): **gem install qtruby4 it includes all needed libraries. Just use ruby 1.8.6 and install the windows gem. I also got ubuntu 10.04 and it works very well with package bindings.
