NuiApi.h include failed in Visual Studio 2012 DLL project - c++

Question

I tried to make console application that is using my DLL that is taking care of Kinect.
When I am building my project I get:
2>e:\projects\c++\vs\kinect dll\consoleapplication1\consoleapplication1.cpp(4):
warning C4627: '#include "KinectDLL.h"': skipped when looking for precompiled header use
2> Add directive to 'stdafx.h' or rebuild precompiled header
2> e:\michał\projects\c++\vs\kinect dll\kinect dll\depthreader.h(4):
fatal error C1083: Cannot open include file: 'NuiApi.h': No such file or directory
Note: ConsolApplication1 and Kinect DLL are 2 projects in the same solution, first one have one dependency – Kinect DLL project as DLL. I have “use precompile headers” turned off in both projects!
Kinect DLL projects:
KinectDLL.h:
#ifdef KINECTDLL_EXPORTS
#define KINECTDLL_API __declspec(dllexport)
#else
#define KINECTDLL_API __declspec(dllimport)
#endif
DepthReader.h:
#pragma once
#include <ole2.h>
#include <Windows.h>
#include "NuiApi.h"
#include "KinectDLL.h"
namespace KinectDLL{
class DepthReader{
static KINECTDLL_API const int depthWidth = 640;
static KINECTDLL_API const int depthHeight = 480;
static KINECTDLL_API const int bytesPerPixel = 4;
public:
KINECTDLL_API DepthReader(void);
KINECTDLL_API ~DepthReader(void);
KINECTDLL_API int Run(HINSTANCE hInstance, int nCmdShow);
private:
HANDLE depthStreamHandle;
HANDLE nextDepthFrameEvent;
HANDLE depthStream;
BYTE* depthRGBX;
bool nearMode;
INuiSensor* sensor;
//HWND m_hWnd;
HRESULT CreateFirstConnected();
void Update();
void ProcessDepth();
};
}
DepthReader.cpp
#include "stdafx.h"
#include "DepthReader.h"
namespace KinectDLL{
DepthReader::DepthReader(void) :
nextDepthFrameEvent(INVALID_HANDLE_VALUE),
depthStreamHandle(INVALID_HANDLE_VALUE),
nearMode(false),
sensor(NULL)
{
// create heap storage for depth pixel data in RGBX format
depthRGBX = new BYTE[depthWidth*depthHeight*bytesPerPixel];
}
… and so on, mostly copy and pase from MS Kinect examples...
Consoleapplication1 project:
Consolapplication1.cpp:
#include "KinectDLL.h"
#include "stdafx.h"
#include "Rotations.h"
#include "Camera.h"
#include "FileLoader.h"
#include "DepthReader.h"
using namespace std;
Camera camera;
Rotations rotations;
FileLoader fileLoader;
KinectDLL::DepthReader depthReader;
… then there is OpenGL, points from file. I am using Kinect to contole the scene, not to display data from it. No depthReader for now.
Clearly I am doing something stupid but I can't see what. I am reading Microsoft examples about DLL in VC++ but I can't see what is wrong.

Answer 1

I have just finished created a dll with some functions that depend on the skeleton stream from the kinect. What I did was something like this:
#ifdef KINECTFUNCTIONSDLL_EXPORTS
#define KINECTFUNCTIONSDLL_API __declspec(dllexport)
#else
#define KINECTFUNCTIONSDLL_API __declspec(dllimport)
#endif
#include <Windows.h>
#include <NuiApi.h>
using namespace std;
#include <string>
namespace KinectFunctions{
class GestureRecognizer
{
public:
Vector4 KINECTFUNCTIONSDLL_API resta(Vector4 vector1,Vector4 vector2);
}
}
and now for the .cpp:
#include "KinectFunctionsDLL.h"
#define _USE_MATH_DEFINES
#include <math.h>
#include <iostream>
#include <fstream>
using namespace std;
namespace KinectFunctions{
Vector4 GestureRecognizer::resta(Vector4 vector1,Vector4 vector2){
Vector4 salida;
salida.x=vector1.x-vector2.x;
salida.y=vector1.y-vector2.y;
salida.z=vector1.z-vector2.z;
return salida;
}
}
Keep in mind that the project you use to create the dll must be created checking the DLL option (it's a checkbox that appears when you choose to create a new project. Like it is shown here:
https://www.youtube.com/watch?v=yEqRyQhhto8
And of course you need to add the dependencies for the kinect dll, the kinect10.lib and the headers, like in any project where you want to use the device.
