I've done a little work on the static initialization side and it looks like the particular one that was an issue for Andy was the way that the automatic initialization of osgViewer's under OSX was making windowing system calls, this isn't normally a problem but when working on a headless machine you'd get error even if you didn't open a window. The solution for this particular issue was making moving the windowing system initialization calls form the constructor to be lazily initialized on demand. To make this work I modified : src/osgViewer/DawinUtils.h src/osgViewer/DawinUtils.mm src/osgViewer/GraphicsWindowCocoa.mm src/osgViewer/GraphicsWindowCarbon.cpp I checked these changes into svn/trunk over the weekend, so they will still need testing by the community. Andy reported success with the first iteration of the changes I made, but made a few more changes since then to clean them up so there is still a bit of risk associated with these changes. Once the community tests them out a bit further we should be confident enough to run with them. Save for the above changes for static it could be that none of the other changes would be required for Andy as this is the only one that his reported as a show stopper so far. There is a but though... I've just checked the 2.8 branch at it doesn't have any Cocoa support at all, so my changes wouldn't be able to merge directly unless you just added Cocoa support to the OSG-2.8 branch. For the OSX community faced with enforced Cocoa usage under 64bit build this would be no bad thing, but it's more work for yourself to merge. Without these we'll just have to keep the 2.8 series as 32bit under OSX, and ear mark the 3.x series for 64bit support under OSX. The sooner I can get 3.0 out the door the less of an issue this will be, as it'll be an easy sell to the community - just use 3.x if you want OSX 64bit support ;-) Cheers, Robert. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
