Having issues trying to retrieve a effect file for directX. If I do not include the D3DX10CreateEffectFromFile() method, the application compiles correctly. If I do include it. I get the following error
1>GXDX.obj : error LNK2019: unresolved external symbol _D3DX10CreateEffectFromFileW@48 referenced in function "public: virtual void __thiscall GXDX::StartUp(struct HWND__ * *,int,int)" (?StartUp@GXDX@@UAEXPAPAUHWND__@@HH@Z)
1>C:\Users\numerical25\Desktop\Intro ToDirectX\GODFILES\GXRenderManager\GXRenderManager\Debug\GXRenderManager.exe : fatal error LNK1120: 1 unresolved externals
My first thought was maybe it is not linking the directx library correctly. But I find that to be off cause I am including the lib files and I am using other methods with no problem. below is my code.
