I wrote a porgram with a few standard dialogs in an SDI (Doc/View enabled) project.

Now that I want to send it to some friends i did set the Use of MFC Use MFC in a static library.

But when i try to build the solution i get the following error:

error LNK2001: unresolved external symbol _IID_IWICImagingFactory

My problem is, that i don´t know what exactly this interface id is, because i did not write any code for COM manually or using any image factory things or equal...

Im a bit lost atm...

May anyone tell me how to solve this and make it work with the static MFC usage?

Thanks in advance!

    Hard to guess what this linker error might have to do with MFC. Nevertheless, Project + Properties, Linker, Input. Additional Dependencies, add "windowscodecs.lib" – Hans Passant Nov 08 '11 at 00:40

There is also a .lib file:

C:\Program Files\Microsoft SDKs\Windows\v7.0A\Lib\ windowscodecs.lib

IWICImagingFactory is defined in wincodec.idl

  • Locate and add wincodec.idl to your MFC project
  • Rebuild and MIDL compiler will generate wincodec_i.c and wincodec_i.h
  • wincodec_i.* files contain the declaration and definition of _IID_IWICImagingFactory

This wasn't my exact problem (different .idl), but same linker error. Google found your question anyway. I copied the .idl file out to a new directory, launched a VS command line, and ran this: 

midl thefile.idl

After it made my .c file, I just copied the const for the IID that I needed, and threw away the rest.
