Thanks for that trick, it is quite useful. Earlier in the day I was cursing the fact that I didn't know how to see what directories OSG was looking in to find the plugins. I went ahead and exported OSG_NOTIFY_LEVEL and ran my application in the two "ways" that I described in my original post. Previously when I would run my application without modifying LD_LIBRARY_PATH, the OpenFlight would NOT be rendered, OSG would print a message about not being able to find the plugin, and my application was gracefully allowed to continue running. Now that I've exported OSG_NOTIFY_LEVEL I get the same behavior and I'm able to see that OSG is looking for the plugin in several directories which don't contain the plugin... Code: Warning: Could not find plugin to read objects from file "MyOpenFlightFile.flt".

I'll preface my next few comments by pointing out that I'm very new to OSG and to a lesser extent CMake. So I don't have a complete understanding of either. Should I even be adding the path to OSG's lib directory to LD_LIBRARY_PATH? Doing this feels somewhat "hackish" (perhaps thats why it results in a crash) because I'd expect that OSG would be able to find its plugins without my help. I'm beginning to think my problem may be a result of how I'm telling CMake that my application is dependent on OSG? My original post has code snippets which show how I'm doing this. It may not be immediately obvious from reading those snippets but they are relying on the FindOpenSceneGraph.cmake module which comes with CMake. So that combined with the fact that it works in Windows gave me reason to feel confident that it would work but maybe I'm just misusing it. If I should be posting this question on a CMake forum then say the word and I'll take my problems over there.[/code] ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=37869#37869 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
