Is there any way you could send me the output of "svn diff" so I can see what was necessary? And fear not, I don't see this as "my" project, so everything that fixes something will be merged. :) My only hope is that with enough eyeballs looking at it, we'll be able to get it in OSG proper before May. > Now, these changes get it to compile and link with 0 errors and 0 warnings for > me.

Hmmm, I've got a few e-mails from people using Windows with success, but I didn't get too many details. If you can figure it out let me know, and I'll change it right away. BTW: SVN changes 3 or 4 times a day lately. :) So, you might get a seriously wonky checkout if you're watching SVN, but I guess that's how things go. For example, if you checkout SVN now you're almost certain to be amazingly confused at my attempts to introduce clipping for WindowInWidget so we can have a proper "scrollable" window. > BTW, osghudversion prints > > OpenSceneGraph HUD Library ¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦ The code for this was taken from the pertinent parts of osgversion, but perhaps I took some strange liberties. The source is only about 4 lines of code, so it would probably be easy to find out. :) On my mahcine it prints: OpenSceneGraph HUD Library 0.1.4 (pre-alpha) > is that normal? > > Anyways, from your videos and the discussion here this really seems like > osgHUD > is on the path to becoming a really useful nodekit.
