Re: [Insight-users] Problem: Integrating ITK in an existing Project (VS 2005, C++) (error LNK2001)

[Paweł Andruszkiewicz]

Hello Chris

I'm using ITK in similar circumstances as you, so VS 2005/2008 with older project which cannot use CMake. I did all the steps of compiling the ITK in the same manner as you, however I've turned off BUILD_EXAMPLES, BUILD_SHARED_LIBS and BUILD_TESTING. My VS project settings are just like yours (if you want I can post them), but I don't have the problem described. I'm not an ITK expert, but I've searched the files of ITK for word "HRGN" and it does not exist there (HRGN is a windows type, not an ITK class). Maybe you have a misplaced namespace somewhere in your project?

kind regards, Pawel Andruszkiewicz
