这个HLSL 在 DX9.0里没问题 但在 最新DXSDK_Aug09 里出问题

[ggg_sss_lll]

matrix ViewMatrix;
matrix ViewProjMatrix;

vector AmbientMtrl;
vector DiffuseMtrl;

vector LightDirection;

//
// Global variables used to hold the ambient light intensity (ambient
// light the light source emits) and the diffuse light intensity (diffuse
// light the light source emits). These variables are initialized here
// in the shader.
//

vector DiffuseLightIntensity = {0.0f, 0.0f, 1.0f, 1.0f};
vector AmbientLightIntensity = {0.0f, 0.0f, 0.2f, 1.0f};

//

//

VS_OUTPUT Main(VS_INPUT input)
{
// zero out all members of the output instance.
VS_OUTPUT output = (VS_OUTPUT)0;

//
// Transform position to homogeneous clip space
// and store in the output.position member.
//
output.position = mul(input.position, ViewProjMatrix);

//
// Transform lights and normals to view space. Set w
// componentes to zero since we're transforming vectors
// here and not points.
//
LightDirection.w = 0.0f;
input.normal.w = 0.0f;
LightDirection = mul(LightDirection, ViewMatrix);
input.normal = mul(input.normal, ViewMatrix);

//
// Compute cosine of the angle between light and normal.
//
float s = dot(LightDirection, input.normal);
if( s < 0.0f )
s = 0.0f;

//
// Ambient light reflected is computed by performing a
// component wise multiplication with the ambient material
// vector and the ambient light intensity vector.
//
// Diffuse light reflected is computed by performing a
// component wise multiplication with the diffuse material
// vector and the diffuse light intensity vector. Further
// we scale each component by the shading scalar s, which
// shades the color based on how much light the vertex received
// from the light source.
//
// The sum of both the ambient and diffuse components gives
// us our final vertex color.
//

output.diffuse = (AmbientMtrl * AmbientLightIntensity) +
(s * (DiffuseLightIntensity * DiffuseMtrl));

错误提示：
error X3025: global variables are implicitly constant, enable compatility mode to allow modification

新版本里都改了些什么呢？
该如何处理，才行呢？？

HLSL...
好熟悉的四个字母啊,帮顶了!

DX9.0的几个版本之间改动确实比较大，全局变量是extern也是常量，在shader里面不能修改，但可以从宿主程序里改。以前的编译器没有强制这一点，现在新的强化了这一要求，改成static试试
