How to create a Direct2D factory

I am creating a Direct2D application and the API overview page says the first step is to create a factory... well I tried that with this function

D2D1CreateFactory(D2D1_FACTORY_TYPE_SINGLE_THREADED, &factory);

but it gives the error

Error   62  error LNK2019: unresolved external symbol _D2D1CreateFactory@16 referenced in function "long __cdecl D2D1CreateFactory(enum D2D1_FACTORY_TYPE,struct _GUID const &,void * *)" (?D2D1CreateFactory@@YAJW4D2D1_FACTORY_TYPE@@ABU_GUID@@PAPAX@Z

I am calling the D2D1CreateFactory function from within the WinMain function.

This is how I initialized the factory pointer

ID2D1Factory *factory;

These are the Include and Library Directories

C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Include
C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Lib\x86

I have experience with direct3D so I am familiar with devices and render targets, but I was under the impression that for direct2D the factory comes first so I haven't created any devices, render targets, etc...

Any help is appreciated.

Solution

  • Try to add to your code this directive.

    #pragma comment(lib, "d2d1.lib")

    It will link d2d1.lib to your object code. You may use this directive to link to the other libs.
