LNK2001, cant get past.

How do I go finding what is wrong with this, I have no external libs dependencies, just a class called complex which defines a datatype for a public member in the co class. I can't seem to figure it out.

 

Error    3    error LNK2001: unresolved external symbol "public: class complex __thiscall co::hTilde_0(int,int)" (?hTilde_0@co@@QAE?AVcomplex@@HH@Z)    C:\Users\Documents\Leadwerks\Projects\cpp_co\Projects\Windows\co.obj    cpp_co

 

Any tip?

Can you show the class? Is that member static? If so you probably didn't init it in the cpp file. If it's a function then you probably didn't create it in the cpp file

Well it's keiths ocean class here : http://www.keithlantz.net/2011/10/ocean-simulation-part-one-using-the-discrete-fourier-transform/

I'm giving a FFT water a go if I figure out how to compile his classes and adapt to Leadwerks.

 

This is the class:

 

class cOcean {
 private:
   bool geometry;						  // flag to render geometry or surface

   float g;							    // gravity constant
   int N, Nplus1;						  // dimension -- N should be a power of 2
   float A;							    // phillips spectrum parameter -- affects heights of waves
   vector2 w;							  // wind parameter
   float length;						   // length parameter
   complex *h_tilde,					   // for fast fourier transform
    *h_tilde_slopex, *h_tilde_slopez,
    *h_tilde_dx, *h_tilde_dz;
   cFFT *fft;							  // fast fourier transform

   vertex_ocean *vertices;				 // vertices for vertex buffer object
   unsigned int *indices;				  // indicies for vertex buffer object
   unsigned int indices_count;			 // number of indices to render
   //GLuint vbo_vertices, vbo_indices;	   // vertex buffer objects

   //GLuint glProgram, glShaderV, glShaderF; // shaders
   //GLint vertex, normal, texture, light_position, projection, view, model; // attributes and uniforms

 protected:
 public:
   cOcean(const int N, const float A, const vector2 w, const float length, bool geometry);
   ~cOcean();
   void release();

   float dispersion(int n_prime, int m_prime);	 // deep water
   float phillips(int n_prime, int m_prime);	   // phillips spectrum
   complex hTilde_0(int n_prime, int m_prime);
   complex hTilde(float t, int n_prime, int m_prime);
   complex_vector_normal h_D_and_n(vector2 x, float t);
   void evaluateWaves(float t);
   void evaluateWavesFFT(float t);
   //void render(float t, glm::vec3 light_pos, glm::mat4 Projection, glm::mat4 View, glm::mat4 Model, bool use_fft);
};

It's telling you that it can't find the method

 

hTilde_0(int,int)

 

inside your .cpp; are you sure its there?

Thanks got it, had a htilde instead of hTilde
