DirectX11着色器编译问题

我正在制作一个简单的DirectX应用程序，将一对三角形一起显示为四面体，这在开始时一直崩溃。我用VS2012调试器检查了错误发生在Shader应该从。fx文件编译的阶段，所以我认为它与Shader有关。我不知道我做错了什么。下面是我使用的着色器的代码。需要援助。

 struct Light
 {
   float3 pos;
   float4 ambient;
   float4 diffuse;
 };
cbuffer cbPerFrame
 {
  Light light;
 };
cbuffer cbPerObject
{
   float4x4 WVP;
   float4x4 World;
};
  struct VS_OUTPUT
 {
  float4 Pos : SV_POSITION;
  float4 worldPos : POSITION;
  float4 color    : COLOR;
  float3 normal : NORMAL;
 };
 VS_OUTPUT VS(float4 inPos : POSITION, float4 inColor : COLOR, float3 normal : NORMAL)
 {
   VS_OUTPUT output;
    output.Pos = mul(inPos, WVP);
output.worldPos = mul(inPos, World);
output.normal = mul(normal, World);
    output.color = inColor;
   return output;
  }    
   float4 PS(VS_OUTPUT input) : SV_TARGET
  {
    input.normal = normalize(input.normal);
    float4 diffuse = input.color;
float3 finalColor = float3(0.0f, 0.0f, 0.0f);
//Create the vector between light position and pixels position
float3 lightToPixelVec = light.pos - input.worldPos;

//Add the ambient light
float3 finalAmbient = diffuse * light.ambient;
//Turn lightToPixelVec into a unit length vector describing
//the pixels direction from the lights position
lightToPixelVec /= d; 
//Calculate how much light the pixel gets by the angle
//in which the light strikes the pixels surface
float howMuchLight = dot(lightToPixelVec, input.normal);
//If light is striking the front side of the pixel
if( howMuchLight > 0.0f )
{   
    //Add light to the finalColor of the pixel
    finalColor += diffuse * light.diffuse;
}
//make sure the values are between 1 and 0, and add the ambient
finalColor = saturate(finalColor + finalAmbient);   
//Return Final Color
return float4(finalColor, diffuse.a);
  }

这是编译应该发生的部分
