Hi Daniel, Could you try:
setenv OSG_CAMERA_THREADING=SingleThreaded Then run your app and see how it behaves. Robert. On 7/25/06, Daniel Larimer <[EMAIL PROTECTED]> wrote:
I am using the default build of OSG 1.1 (I believe it is AGL), but the problem existed in earlier builds. This crash does not show up on our Dual Core x86-64 systems. If you place a mutex inside SceneView::flushAllDeletedGLObjects() and SceneView::flushDeletedGLObjects(time) then you can eliminate the crash enough to view the cow model; however, when running different data sets I get a crash here: Thread 7 Crashed: 0 libosg.dylib 0x0043bffc osg::Drawable::getExtensions (unsigned, bool) + 940 1 libosg.dylib 0x0044eb30 osg::Geometry::drawImplementation(osg::State&) const + 96 2 libosgUtil.dylib 0x0103ebdc osgUtil::RenderLeaf::render (osg::State&, osgUtil::RenderLeaf*) + 3580 3 libosgUtil.dylib 0x01038e0c osgUtil::RenderBin::drawImplementation(osg::State&, osgUtil::RenderLeaf*&) + 380 4 libosgUtil.dylib 0x01047a00 osgUtil::RenderStage::drawImplementation(osg::State&, osgUtil::RenderLeaf*&) + 1056 5 libosgUtil.dylib 0x01047af4 osgUtil::RenderStage::drawInner(osg::State&, osgUtil::RenderLeaf*&, bool&) + 212 6 libosgUtil.dylib 0x010474e4 osgUtil::RenderStage::draw (osg::State&, osgUtil::RenderLeaf*&) + 964 7 libosgUtil.dylib 0x0105d14c osgUtil::SceneView::draw() + 12924 8 libcove.1.dylib 0x02044fd0 Cove::OsgSceneHandler::draw (Cove::Camera const*) const + 172 (OsgSceneHandler.cpp:134) 9 libcove.1.dylib 0x02017d80 Cove::Camera::draw() const + 392 (Camera.cpp:185) 10 libcove.1.dylib 0x0203fbcc Cove::GLWidget::frame (Cove::FrameState const*) + 372 (GLWidget.cpp:132) 11 libcove.1.dylib 0x0202d7a8 Cove::ContextThread::run() + 360 (ContextThread.cpp:158) 12 QtCore 0x0a1d57ec QThreadPrivate::start(void*) + 228 13 libSystem.B.dylib 0x9002bc28 _pthread_body + 96 This crash does not happen on Linux / X11.
