Hi Sean,
I had similar problems in the past as you and Chuck. My fix was to make sure the project-settings for osg and my own project where the same and set to FALSE: Symbols hidden by default (GCC_SYMBOLS_PRIVATE_EXTERN): FALSE and eventually Inline hidden methods (GCC_INLINES_ARE_PRIVATE_EXTERN): FALSE Cheers, Stephan Am 27.01.12 18:11, schrieb Sean Sullivan: > Hey guys, > > I'm trying to pass an osgViewer::GraphicsWindowCocoa::WindowData to my traits > object with CreateOnlyView specified.
