Hi Jordi and Jan, thank you for support. After reading Jordi's post i thought to install a i386 arch of Ubuntu hoping to solve the problem... but then, reading Jan's post i changed idea... i have to model in linux a calcio balilla table (i don't know if there's an english translation for calcio balilla, i'm sorry!), using a sketchup model [1] and and some animation and/or interaction. So, my teacher suggested me to use osgBullet. osgBullet depends on osg, bullet and osgWorks, but to load hte model i need collada-dom.

Problem solved ... To be honest, COLLADA is a pain to use because there are several incompatible versions of the DOM in use and I have yet to find a tool that actually supports it properly. E.g. 3DS Max can import/export COLLADA but I haven't managed to get Blender, OSG nor Bullet to load the result. Blender supports two versions, Bullet loads one, OSG also one out of that. Max doesn't load whatever Blender produces, regardless of version, etc. I have no idea about Maya or Sketchup, perhaps that has a bit better support.

Re: [osg-users] OSG, bullet physics, collada and sketchup models on Ubuntu
Hi Axel, OSG can't load .skp files with collada plugin, you must use collada models (.dae) also downloadables form google wharehouse. About compiling the plugin you have to pay attention to the dom version used, take a look to [1] to get collada plugin compiled. We are using collada models on Ubuntu without problems.

[1] http://www.openscenegraph.org/projects/osg/wiki/Support/KnowledgeBase/Collada 2010/11/2 Axel Spirtaat loginv...@gmail.com Hi all, i correctly installed osg 2.8.1 (by apt - ubuntu/debian package manager) and bullet physics 2.76 building the sources. When i tried to load a sketuchup file (.skp) osgviewer reported an error. I read that i need collada-dom to load this kind of model. Is it right? However, i also tried to build collada, but there are a lot of bugs for linux and seem to be no more supported... i fixed some of them but not all. So i seen that bulet physics 2.75 (an older version) have collada included in its sources and i tried to build it too :P (hope successfully). Now i think i have to re-installe the osg by sources selecting also the collada plugin. Is this right? Since i installed in past also osgWorks and osgBullet, and had some problem with bullet physics, i think there's a lot of garbage in my libraries and maybe i need to reinstall the whole Ubuntu... To prevent future problems can anyone answer to next questions? 1) Does OSG need collada to load sketchup files? 2) Is there anyone who succesfully installed collada-dom on ubuntu/linux? 3) can anyone provide me a link to a really good tutorial to install collada-dom and load sketchup files using osg?

Re: [osg-users] OSG, bullet physics, collada and sketchup models on Ubuntu
Hello Axel, Unfortunately, I have bad news for you. The collada inside Bullet and the Collada as used by OSG are two different versions. If you try to link the libraries, it will fail, even after you get the library problem solved (32bit vs 64bit architecture issue?). The problem gets worse because it is not possible to just simply port bullet code to the same Collada OSG has (different API!). When I was trying to use Collada with Bullet and OSG to load models including physics, I had to do extensive changes to both Bullet and osgBullet to make this work :( If you do not absolutely need physics support for Collada, just disable Collada in Bullet, it will save you a lot of headaches.
