Hi. I'm trying to build OSG into my application. I've started with OSG logging. I've attached sample code that depicts the problem. After you run the program and than stop it by pressing ESC, you can see the following output:
$ ./test abc DatabasePager::RequestQueue::~RequestQueue() Destructing queue. DatabasePager::RequestQueue::~RequestQueue() Destructing queue. DatabasePager::RequestQueue::~RequestQueue() Destructing queue. DatabasePager::RequestQueue::~RequestQueue() Destructing queue. ~RegisterWindowingSystemInterfaceProxy() GraphicsContext::setWindowingSystemInterface() 0 0x7ffd0fd71470 abc is printed after all delete operators take place. Somehow Viewer is deleted after I actually delete it. ~RegisterWindowingSystemInterfaceProxy() comes from the destruction of this static variable: http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/src/osgViewer/GraphicsWindowX11.cpp?rev=12923#L2137 GraphicsContext::setWindowingSystemInterface() 0 0x7ffd0fd71470 comes from the destructor of the above variable: http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/src/osgViewer/GraphicsWindowX11.cpp?rev=12923#L2132 This means OSG uses static variables which initialization and deinitialization times are unknown, which results in: 1) I can't really control my OSG logger lifetime; 2) I miss RegisterWindowingSystemInterfaceProxy() initialization in logger (and possibly many others). The only option is to create Logger specifically for OSG and let it die at an unknown time (after all my cleanup procedures), possibly causing me problems later. Can we please make it non-static?
