Question

I have three .cpp files these are named MeshLoader.cpp, DynamicXMesh.cpp and StaticXMesh.cpp

I have a function in the MeshLoader.cpp file named FindTexturePath and I want to call and use it in the DynamicXMesh.cpp and StaticXMesh.cpp files.

I have included MeshLoader.cpp(#include “MeshLoader.cpp”) file in boot XMesh files and of course get an error that says function is already defined…

Also I tryed to use pragma once and ifndef …:

//This is "MeshLoader.cpp"
pragma once

#ifndef MLOAD
#define MLOAD
  char* FindTexturePath( char* TexturePath ,LPSTR FileNameToCombine){
      ...
      ...
      ...
  }
#endif

/////

//This is StaticXMesh.cpp
#include "MeshLoader.cpp"
...
...
...
this->StatXMeshTexturePath = FindTexturePath(StatXMeshTexturePath,d3dxMaterials[i].pTextureFilename);
...
...

/////
And same call for DynamicXMesh.cpp

I hope I explained myself clear enough… Thank you for givin your time…

You need to create MeshLoader.h, and put something like this in it

#ifndef INCLUDED_MESH_LOADER_H
#define INCLUDED_MESH_LOADER_H

char* FindTexturePath( char* TexturePath ,LPSTR FileNameToCombine);

#endif

And include that in your other cpp files. Each of the cpp files just need the declaration of FindTexturePath to compile. So whenever you need to make a function in a cpp public to other cpp files, create a .h file that has the function declarations in.
