I got stuck at these link errors while compiling "Torque Shader Engine"
using Intel Compiler.
5>atlasGeomCollision.obj : error LNK2019: unresolved external symbol
"public: bool __thiscall QuadTreeTracer::castRay(class
Point3F const &,class Point3F const &,class RayInfo *)"
(?castRay@QuadTreeTracer@@QAE_NABVPoint3F@@0PAVRayInfo@@@Z) referenced
in function "public: bool __thiscall AtlasGeomChunkTracer::castRay(class
Point3F const &,class Point3F const &,class RayInfo *)"
(?castRay@AtlasGeomChunkTracer@@QAE_NABVPoint3F@@0PAVRayInfo@@@Z)
I think the class hierarchy is a valid C++ construct (no problem in VS 2005) but the Intel
compiler doesn't like it.
In \engineutilquadTreeTracer.h
class QuadTreeTracer
{
...
public:
bool castRay(const Point3F &start, const Point3F &end,
RayInfo *info);
}
In
\engineatlas
esourceatlasGeomCollision.h
class AtlasGeomChunkTracer : public QuadTreeTracer
{
...
public:
bool castRay(const Point3F &start, const Point3F &end,
RayInfo *info);
};
in \engineatlasatlasGeomCollision.cpp
bool AtlasGeomChunkTracer::castRay(const Point3F &start, const Point3F
&end, RayInfo *info)
{
....
return QuadTreeTracer::castRay(start, end,
info); <----- the linker couldn't find this function on the
base class.
}
Thanks for any help to solve this problem....
