Hi, I'm trying to compile this sample code from Introduction to 3D Game Programming with DirectX 9.0c Shader Approach. But I get a compile error. Here's the code: #include <d3dx9.h> #include <iostream> using namespace std; // Overload the "<<" operators so that we can use cout to // output D3DXVECTOR3 objects. ostream& operator<<(ostream& os, D3DXVECTOR3& v) { os << "(" << v.x << ", " << v.y << ", " << v.z << ")"; return os; } int main() { // Using constructor, D3DXVECTOR3(FLOAT x,FLOAT y,FLOAT z); D3DXVECTOR3 u(1.0f, 2.0f, 3.0f); // Using constructor, D3DXVECTOR3(CONST FLOAT *); float x[3] = {-2.0f, 1.0f, -3.0f}; D3DXVECTOR3 v(x); // Using constructor, D3DXVECTOR3() {}; D3DXVECTOR3 a, b, c, d, e; // Vector addition: D3DXVECTOR3 operator + a = u + v; // Vector subtraction: D3DXVECTOR3 operator - b = u - v; // Scalar multiplication: D3DXVECTOR3 operator * c = u * 10; // ||u|| float length = D3DXVec3Length(&u); // d = u / ||u|| D3DXVec3Normalize(&d, &u); // s = u dot v float s = D3DXVec3Dot(&u, &v); // e = u x v D3DXVec3Cross(&e, &u, &v); cout << "u = " << u << endl; cout << "v = " << v << endl; cout << "a = " << a << endl; cout << "b = " << b << endl; cout << "c = " << c << endl; cout << "d = " << d << endl; cout << "e = " << e << endl; cout << "||u|| = " << length << endl; cout << "u dot v = " << s << endl; return 0; } And here's the error: Embedding manifest... mt.exe : general error c10100b1: Failed to load file "..\Debug\3dvectors.exe". The system cannot find the path specified. Is this a linking error? The project is an empty project. Thanks in advance for any help. -------------edit--------------- I'm using Visual C++ 2008 Express Edition and have DirectX 9 installed.

Hi!

If I get into this kind of trouble, I always use the following.
I download a minimal dx9 tutorial (nehe or something), I try to compile and run.
It should work.
Then I use this project file, include my sources in small steps, it should work.

OK so I fixed my first problem. I just had to go to File > move to > folder. However I ran into another problem, and I believe that it is now a linking error.

Error:

I looked all over the internet to see how others solved the problem, and it seems that it is definitely a linking problem. However, I don't know what's wrong. I'm pretty sure I set up the directories right. What else do I have to do? Anyone have any idea?

----edit----
OK i figured out the problem. I forgot to add the d3dx9.lib file to additional dependencies.

Thanks for your guys support from earlier.

Thanks for your input TheUnbeliever. I didn't see your post at the time I edited my post (didn't refresh the page).
