Hi,
Ogre 1.0.6 SDK works fine but I get some error messages when I try to compile the plsm sdk version.

Any idea what went wrong?



OgrePagingLandScapeOcclusionSWTraversal.cpp

E:\Programme\Microsoft Visual Studio 8\VC\include\xutility(323) : error C2664: 'bool Ogre::FrontToBackNodeSorterOperator::operator ()(const Ogre::OcclusionElement *&,const Ogre::OcclusionElement *&) const' : cannot convert parameter 1 from 'Ogre::OcclusionElement *' to 'const Ogre::OcclusionElement *&'

        Conversion loses qualifiers

        E:\Programme\Microsoft Visual Studio 8\VC\include\algorithm(1676) : see reference to function template instantiation 'bool std::_Debug_lt_pred<_Pr,Ogre::OcclusionElement*,Ogre::OcclusionElement*>(_Pr,_Ty1 &,_Ty2 &,const wchar_t *,unsigned int)' being compiled

        with

        [

            _Pr=Ogre::FrontToBackNodeSorterOperator,

            _Ty1=Ogre::OcclusionElement *,

            _Ty2=Ogre::OcclusionElement *

        ]

express or other version ?

try removing the & and the const ?
from



(const Ogre::OcclusionElement *&,const Ogre::OcclusionElement *&) const



(Ogre::OcclusionElement *, Ogre::OcclusionElement *) const

hmm can't get this to work.
Should be a full blown vc2005 professional (as a student I got it for free from a msdn academic program).
I remember that I had a similar problem and error messages a few weeks ago with std::swap.
I wasn't able to compile my game engine written in vc2003 with the new vc2005 and i had nearly identical error messages (always in template instantiations that in my case used std::swap).
The strange this is, that when I took this peace of code out into a new project it compiled flawlessly. Already asked ms for support but they couldn't reproduce it.
Any ideas before I completly reinstall windows and vc2005?

CVS code has 2 flavor try paste these instead of actual SDK code :



//-----------------------------------------------------------------------

inline bool operator()(OcclusionElement*& a, OcclusionElement*& b) const 

{

	// could check if both distance == 0 then order visible first// ?

	return vectorToBoxDistance (*a, pos) > vectorToBoxDistance (*b, pos);

}       

//-----------------------------------------------------------------------

inline bool operator()(const OcclusionElement*& a, const OcclusionElement*& b) const 

{

	// could check if both distance == 0 then order visible first ?

	return vectorToBoxDistance (*a, pos) > vectorToBoxDistance (*b, pos);

}
