OpenSceneGraph (+ SDL)

[mjpm]

Hello,

I'm trying to get OpenSceneGraph (http://www.openscenegraph.org/) to work with CB.
I set the include and lib paths in CB but I get many errors when trying to compile one of the examples.

Maybe someone has worked with OSG and CB in combination and can give me a hint?!

As a second part of this question, has anyone worked with SDL and OSG in combination?
I wanted to use SDL for window handling and maybe event handling.


Regards,

Marcel

It looks like it isn't actually finding any of the libraries.  Have you added the OSG libraries to the linker(not just the path?).

Please repeat the log having enabled the *full* compiler log (see my sig).
With regards, Morten.

Hello,

I found two files for the example

Code: cpp

// C++ source file - (C) 2003 Robert Osfield, released under the OSGPL.
//
// Simple example of use of Producer::RenderSurface to create an OpenGL
// graphics window, and OSG for rendering.

#include <Producer/RenderSurface>
#include <osg/Timer>
#include <osgUtil/SceneView>
#include <osgDB/ReadFile>


int main( int argc, char **argv )
{
    if (argc<2)
    {
        std::cout << argv[0] <<": requires filename argument." << std::endl;
        return 1;
    }

    // load the scene.
    osg::ref_ptr<osg::Node> loadedModel = osgDB::readNodeFile(argv[1]);
    if (!loadedModel)
    {
        std::cout << argv[0] <<": No data loaded." << std::endl;
        return 1;
    }

    // create the window to draw to.
    osg::ref_ptr<Producer::RenderSurface> renderSurface = new Producer::RenderSurface;
    renderSurface->setWindowName("osgsimple");
    renderSurface->setWindowRectangle(100,100,800,600);
    renderSurface->useBorder(true);
    renderSurface->realize();

    // create the view of the scene.
    osg::ref_ptr<osgUtil::SceneView> sceneView = new osgUtil::SceneView;
    sceneView->setDefaults();
    sceneView->setSceneData(loadedModel.get());

    // initialize the view to look at the center of the scene graph
    const osg::BoundingSphere& bs = loadedModel->getBound();
    osg::Matrix viewMatrix;
    viewMatrix.makeLookAt(bs.center()-osg::Vec3(0.0,2.0f*bs.radius(),0.0),bs.center(),osg::Vec3(0.0f,0.0f,1.0f));

    // record the timer tick at the start of rendering.
    osg::Timer_t start_tick = osg::Timer::instance()->tick();

    unsigned int frameNum = 0;

    // main loop (note, window toolkits which take control over the main loop will require a window redraw callback containing the code below.)
    while( renderSurface->isRealized() )
    {
        // set up the frame stamp for current frame to record the current time and frame number so that animtion code can advance correctly
        osg::ref_ptr<osg::FrameStamp> frameStamp = new osg::FrameStamp;
        frameStamp->setReferenceTime(osg::Timer::instance()->delta_s(start_tick,osg::Timer::instance()->tick()));
        frameStamp->setFrameNumber(frameNum++);

        // pass frame stamp to the SceneView so that the update, cull and draw traversals all use the same FrameStamp
        sceneView->setFrameStamp(frameStamp.get());

        // update the viewport dimensions, incase the window has been resized.
        sceneView->setViewport(0,0,renderSurface->getWindowWidth(),renderSurface->getWindowHeight());

        // set the view
        sceneView->setViewMatrix(viewMatrix);

        // do the update traversal the scene graph - such as updating animations
        sceneView->update();

        // do the cull traversal, collect all objects in the view frustum into a sorted set of rendering bins
        sceneView->cull();

        // draw the rendering bins.
        sceneView->draw();

        // Swap Buffers
        renderSurface->swapBuffers();
    }

    return 0;
}

which are

GNUmakefile.inst

Code

TOPDIR = ../..
include $(TOPDIR)/Make/makedefs

CXXFILES =\
	osgsimple.cpp\

LIBS     += -lProducer -losgDB --losgUtil -losg $(GL_LIBS) $(X_LIBS) $(OTHER_LIBS) 

EXEC = osgsimple

INC += $(PRODUCER_INCLUDE_DIR) $(X_INC)
LDFLAGS  += $(PRODUCER_LIB_DIR)

include $(TOPDIR)/Make/makerules

and

GNUmakefile

Code

TOPDIR = ../..
include $(TOPDIR)/Make/makedefs 

CXXFILES =\
	osgsimple.cpp\

LIBS     += -lProducer -losgDB -losgUtil -losg $(GL_LIBS) $(X_LIBS) $(OTHER_LIBS) -lOpenThreads

INSTFILES = \
	$(CXXFILES)\
	GNUmakefile.inst=GNUmakefile

EXEC = osgsimple

INC      += $(X_INC) 
LDFLAGS  += -L/usr/X11R6/lib


ifeq ($(USE_OPEN_THREAD),1)
    DEF         += -D_USE_OPEN_THREAD
    INC         += $(INC_OPEN_THREAD)
    LDFLAGS     += $(LIB_OPEN_THREAD)
    LIBS        +=  -lOpenThread
endif

include $(TOPDIR)/Make/makerules 

So I added Producer.lib, osgDB.lib, osgUtil.lib, osg.lib and OpenThreadsWin32.lib to Settings -> Compiler and debugger -> Linker -> Link libraries without success.

I also tried adding all other libs and #including the gl headers as it reads "GL_LIBS" in the makefile, all with no success.

Why do you have the full library path there?  You should just add the name of the library, the part after the "-l" in the Makefile.  The '-L"C:\Program Files\OpenSceneGraph\lib"' (which is where the library is) tell the linger where to look for them.

[mjpm]

Hello,

when I insert the libs via the browse button, it gets inserted with the full command line.
And when I delete the rest of the command line and just leave the lib name like Producer.lib compilink/linking stops at the very first lib, because it can not be found.

I also tried combinations of backslah trailing in the lib path and enforcing quotes etc., still no success.

Marcel

Hello,

the problem is solved.

The Problem is that the release just is not suitable for MingW, it could not work.
For MingW I have to compile it all myself.

Marcel
