Hi.
Currently, I'm doing a lot of refactoring / reimplementation on my
software system. One of the tasks among others is porting the beast to
windows - and that's giving me serious headaches - maybe one of the more
windows experienced of you can give me a hint here.
Let me shortly sketch my architecture:
I have a program, that uses 2 dlls, called Common.dll (doesn't use
OpenSG at all) and System.dll (this one does) that are used by the main
program. While System defines most of the (graphics related) framework,
all the functionality is encapsulated in plugins that are loaded at
runtime using dlsym on Linux / LoadLibrary on Windows. For example,
there are abstract Display and DisplayImp classes defined in the
System.dll and a derived SimpleSceneManagerDisplay class implemented as
a plugin (Display_simpleSceneManager.dll).
Everything works perfectly on Linux, but on Windows (using MSVC2005
Professional, and a 1.8 daily build) the following happens:
If I add OSG::GLUTWindow::create() in a class of my System.dll, it
returns a valid WindowPtr. But if I use the same call in my plugin, it
returns NullFC. I use the same compiler / linker options for both
(attached the debug versions below). Both calls are done in the same thread.
* Under what circumstances returns OSG::GLUTWindow::create() null? After
looking into the code, the create call copies a prototype and returns it
- when can that go wrong?
* Is there anything to consider when using OpenSG in a dll that is
loaded via LoadLibrary? Has anybody had problems with that before?
I also have a second plugin (Scene_default.dll) that does the following
in its constructor:
_transform = OSG::ComponentTransform::create();
_sceneRootNode = OSG::Node::create();
beginEditCP(_sceneRootNode);
_sceneRootNode->setCore(_transform);
_sceneRootNode->addChild(OSG::makeTorus(1.5,2,32,32));
endEditCP(_sceneRootNode);
But here, I get valid NodePtrs for _transform and _sceneRootNode, so I
doubt that this is a general "::create" problem. osgInit is called
before loading the plugins in the System.dll. But moving it to the
display plugin had no effect either so this is propably not the cause.
Ah, and of course, the Tutorials all work fine, so GLUT and all that is
obviously working. The compiler / linker options are copied from one of
the tutorials (except that .exe was changed to .dll).
Any ideas?
Thanks in advance,
Dominik
