[c++,dx11], compiler shader from Memory

category: code [glöplog]

Heej,

i try to compile a vertex shader on runtime. But it is not working. How to fix it??

Code:


	char *VERTEXSHADER = R"(
	cbuffer PerApplication : register(b0)
	{
		matrix projectionMatrix;
	}

	cbuffer PerFrame : register(b1)
	{
		matrix viewMatrix;
	}

	cbuffer PerObject : register(b2)
	{
		matrix worldMatrix;
	}

	struct AppData
	{
		float3 position : POSITION;
		float3 color : COLOR;
	};

	struct VertexShaderOutput
	{
		float4 color : COLOR;
		float4 position : SV_POSITION;
	};

	VertexShaderOutput SimpleVertexShader(AppData IN)
	{
		VertexShaderOutput OUT;
		matrix mvp = mul(projectionMatrix, mul(viewMatrix, worldMatrix));
		OUT.position = mul(mvp, float4(IN.position, 1.0f));
		OUT.color = float4(IN.color, 1.0f);

		return OUT;
	}
	)"; 


	// Load the compiled vertex shader.
	ID3DBlob* vertexShaderBlob=NULL;
	ID3DBlob* vertexShaderBlobError=NULL;

	hr= D3DCompile(
		&VERTEXSHADER,			//in      LPCVOID pSrcData,
		sizeof(VERTEXSHADER),	//in      SIZE_T SrcDataSize,
		NULL,					//in_opt  LPCSTR pSourceName,
		NULL,					//in_opt  const D3D_SHADER_MACRO pDefines,
		NULL,					//in_opt  ID3DInclude pInclude,
		"SimpleVertexShader",	//in      LPCSTR pEntrypoint,
		"vs_5_0",				//in      LPCSTR pTarget,
		D3DCOMPILE_OPTIMIZATION_LEVEL3 ,//in      UINT Flags1,
		NULL,					//in      UINT Flags2,
		&vertexShaderBlob,		//out     ID3DBlob ppCode,
		&vertexShaderBlobError	//out_opt ID3DBlob ppErrorMsgs
	);

	if (FAILED(hr)) return false;

Thanks for helping :-)

Very cursory look but if VERTEXSHADER is char*, shouldnt you pass that instead of &VERTEXSHADER as a first parameter?

I tryed everything , VERTEXSHADER or &VERTEXSHADER , no difference

Are there messages in vertexShaderBlobError?

Yes,
- __vfptr D3DCompiler_47.dll!0x5a4d0a94 (Symbole für zusätzliche Informationen laden) {D3DCompiler_47.dll!0x5a74d811, ...} void * *

- __vfptr D3DCompiler_47.dll!0x5a4d0a94 (Symbole für zusätzliche Informationen laden) {D3DCompiler_47.dll!0x5a74d811, ...} void * *

- 0x006b5c38 <Keine Informationen verfügbar. Für D3DCompiler_47.dll wurden keine Symbole geladen> ID3D10Blob *

I have no clue about D3D but I assume D3DCompile expects the length of the source and not sizeof(char*).

YES, thats it.. :-) Now it is compiling without Errors... :-)
