[wxruby-users] libgstreamer, slackware => libgconf.......???

[rvnues at tesco.net]

Hoi, Mario and Alex,
 
Thanks for your ideas and I'll be able to get ahead with them. 

I dunno whether I am the only sole on linux planet wihout gconf or libgstreamer.... but I used the gem system of installing wxruby, which is a great tool. Of course I can give it a try to compile wxRuby myself (and hopefully not running into other dependencies when omitting Wx::MediaCtrl ) but, by accidentally stumbling on your discussion about modularisation on http://rubyforge.org/pipermail/wxruby-development/2007-June/000790.html , the ideas in here might provide a long-term solution to the problems I encountered. Please do not start changing things for my sake (I was only trying wxRuby out as part of discovering ruby. I've made stuff with Java and am looking for a friendlier programming environment) and probably can get enough done with 1.9.2 before needing to upgrade...  Please keep focused on the main direction of wxRuby.

I think OpenGL is another one that may require an additional dependency, but it shouldn't be that large of one, since most Modern Distro's come with OpenGL.

Why does a gui wrapper program needs coupling to a media streaming library or a system to store user-preferences??? ("GStreamer is a library that allows the construction of graphs of media-handling components, ranging from simple Ogg/Vorbis playback to complex audio"), ("GConf is a system for storing application preferences. It is intended for user preferences"). Also nothing of such new dependencies can be found in the ChangeLog (for 1.9.3, the 'oldest' version that does not run properly).  I hope one can sort this at the wxruby end. Until then I will have to use 1.9.2, or try the Java libaries (SWT or Swing) via Jruby.
