首先按照网友所给出的安装配置详细过程进行了DirectX 10 SDK的安装，本文是对其的一个补充，增加了一个简单的测试用例，并对测试中出现的问题，进行了解决，现将完整过程记录如下。
1.下载并安装DirectX 10 SDK，在VS2010下配置DirectX SDK搭建DirectX开发环境，详细见网友yy649487394博客：
2.在VS 2010中添加如下测试用例（关于向量的运算）：
#include#include using namespace std;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 L = D3DXVec3Length(&u);//d = u / ||u||D3DXVec3Normalize(&d, &u);// s = u dot vfloat s = D3DXVec3Dot(&u, &v);// e = u x vD3DXVec3Cross(&e, &u, &v);cout << "u = " << u << endl;cout << "v = " << v << endl;cout << "a = u + v = " << a << endl;cout << "b = u - v = " << b << endl;cout << "c = u * 10 = " << c << endl;cout << "d = u / ||u|| = " << d << endl;cout << "e = u x v = " << e << endl;cout << "L = ||u|| = " << L << endl;cout << "s = u.v = " << s << endl;return 0;}
调试时出现错误：error LNK2019: unresolved external symbol _D3DXVec3Normalize@8 referenced in function _main
解决办法如下：
依次点击：【Project】-【Property】-【Configuration Properties】-【VC++ Directories】-【Library Directories】，添加DirectX安装目录下Lib\X86（之前考虑到电脑是64位，故只添加了Lib\X64），如我添加的是E:\DX9\Lib\X86。
添加后，测试示例成功运行！
