DirectWrite Errors in Win32 Application
Hello, I am trying to get direct write to work in my application. I have been reading through a sample application called 'DWriteHelloWorld' that is part of the windows sdk but havent had much luck. Here is the error and my code
Code:
Error 1 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) C:\DWrite_Test\DWrite_Test\DWrite_Test.obj
Code:
Error 2 error LNK2019: unresolved external symbol __imp__DWriteCreateFactory@12 referenced in function "long __cdecl CreateDeviceIndependentResources(void)" (?CreateDeviceIndependentResources@@YAJXZ) C:\DWrite_Test\DWrite_Test\DWrite_Test.obj
Code:
Error 3 error LNK1120: 2 unresolved externals C:\DWrite_Test\Debug\DWrite_Test.exe 1

Edit, I have no idea why it put all my code on one line
