Problem with setHeightFunction

Hello,

I use Ogre 1.7.3 and ogre-paged 1.1.4
For the Terrain i used the new Terrain system.

I created a Class which create the Terrain and this class also should create the Grass.
In this Class i can't make mTerrainGroup static, but the getTerrainFunction must be static.

Compile Error VS shows me is:
Error 1 error LNK2001: unresolved external symbol "protected: static class Ogre::TerrainGroup * ForestTerrainLoader::mTerrainGroup" (?mTerrainGroup@ForestTerrainLoader@@1PAVTerrainGroup@Ogre@@A) D:\ProjectForest\ProjectForest\ForestTerrainLoader.obj ProjectForest
Error 2 error LNK1120: 1 unresolved externals D:\ProjectForest\ProjectForest\bin\Release\\ProjectForest.exe ProjectForest

};



#endif // #ifndef __ForestTerrainLoader_h_

getTerrainFunction

float ForestTerrainLoader::getTerrainHeight(const float x, const float z, void *userData)

{

	return mTerrainGroup->getHeightAtWorldPosition(x, 1000, z);

}

i hope somebody can help me.
