C++, MVS, OSG, Qt ... ?!

PLA

Hi everybody!
I'm trying to program in C++ using:
Visual Studio 2005
Qt 4.4.3
OpenSG

My OS is Win XP

Building shows me a linker error i can't solve.

That's the program (a really base one):

Code:

#include <QtGui/QApplication>
#include <OpenSG/OSGConfig.h>
#include <OpenSG/OSGNode.h>
#include <OpenSG/OSGSimpleGeometry.h>
#include <OpenSG/OSGSimpleSceneManager.h>

using namespace std;
using namespace osg;



int main(int argc, char *argv[])
{
osgInit(argc,argv); // Init the OpenSG subsystem
QApplication a(argc, argv);
a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));

return a.exec();
}

And that's the build log:

Code:

Can anyone suggest me something?

Thank you!

the warning on /Gm isn't the problem, its just saying if you want to do rebuild of source files you changed then you need to enable saving of symbolic info as well.

The real error is the link error. The linker can't find the lib.obj for the OpenSG library.

Look in the OpenSG directory to see if its there perhaps under directory:

C:\Program Files\OpenSG\lib

ie C:\Program Files\OpenSG\lib\lib.obj

if thats the case then you'll need to see if there's a setting in Visual C++ to change where the compiler/linker looks for Open SG files.

There's not that file anywhere... i think MVS is searching for something useless... :/
Why would it search for a .obj in a lib path?!

But maybe i don't know what i'm speaking of...

Am i wrong? :D

a lib is a collection of objs so its reasonable to be there.

it may be that you don't have a full install of the Open SG code but only its header files (ie the include files).

when you loaded Open SG on your system did you need to build it?
