error in the error class?

i get the following error while compiling my own project... what do i miss?
im using vs2005
i added the dll file i compiled(compiling went smoothly) from svn to my debug directory (where the exe comes) and told the linker to look in all the correct folders (nxogredir\lib) and use the _d.lib from nxogre. to me it looks all correct but... this message says otherwise (i also added the nesecary libs n include from ageia)
error LNK2001: unresolved external symbol "private: static class NxOgre::Error * NxOgre::Error::mError" (?mError@Error@NxOgre@@0PAV12@A)

/edit: see post below how i fixed myself

ok so i changed the files NxOgreError.ccp and .h in the following way.

in the .h file the getinstance function wasa declared and implemented...
i simply moved the actual implementation to the .cpp file and recompiled it and now i dont get that error anymore...

he who is working on this(betajean?) could you take a look in this? maybe a fix you'd prefer? id be happy to adjust to that.
