i'm trying to compile an Ogre/Qt application following the tutorial on the Ogre wiki and i get these linkler errors:

@1>OgreRenderer.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall QX11Info::~QX11Info(void)" (_imp??1QX11Info@@QAE@XZ) referenced in function "protected: virtual void __thiscall CJokeRendererOpenGL::initializeGL(void)" (?initializeGL@CJokeRendererOpenGL@@MAEXXZ)

which lib do i have to link to get this to work?

It looks like the xorg's devel package that contains X's headers is not installed on your computer.

The error messages look like this is on Windows? In which case it would be odd to have QX11Info in there. Which platform are you building on?

windows 7 and the tutorial for Ogre had that so i assumed it needed to be added

Have you installed "Microsoft Visual C++ Dependencies Package" and have you read the corresponding thread "here":http://www.ogre3d.org/forums/viewtopic.php?f=1&t=54533 ?

It is, but this is the part that depends on Xorg, which is separate from Qt.
