在研究HLSL时编译一个demo出现了error X3539的问题

解决方案

将代码中的ps_1_1 改为ps_2_0

1	`PixelShader = compile ps_1_1 PS();`

或者是在D3DXCompileShaderFromFile函数中将对应的ps_1_1改为ps_2_0

//create pixel shader
ID3DXBuffer* codeBuffer        = 0;
ID3DXBuffer* errorBuffer       = 0;
HRESULT hr = D3DXCompileShaderFromFile("ps.txt",
                                       0,
                                       0,
                                       "PS_Main", // entry point function name
                                       "ps_2_0",  //ps_1_1 is error X3539
                                       D3DXSHADER_DEBUG,
                                       &codeBuffer,
                                       &errorBuffer,
                                       &pixelConstTable);
