Can't build the Engine with the "Development" configuration

Has anyone ever seen these Linker Errors?: (For some reason I’m getting these errors when building with “Development” configuration. But when I build with “Development_Editor” configuration it works fine, but when I try to export I get these EXACT same errors when trying to “Package” the project for “Windows 64-bit”. Thanks in advance.

**Edit #1: **
I moved over to a Windows 7 Machine, pulled the Engine Source down from the repository, and without making any changes. It compiles successfully under the “Development” build, and the “Development_Editor” build. So this seems like a Windows 8 Issue. My next question is, Is there a way to make this compile successfully under Windows 8? (Development Configuration) My project requires that I use Windows 8 and no other OS. Thanks in advance again. Also any STAFF input is Greatly appreciated. :slight_smile:

I don’t know for sure with these functions. But, I was using functions available only to the Editor build, and are not available at Development. When you build Development follow back some of the missing funcitons to the class they are in and see if they are in an Editor only #ifdef. If so, you are going to need to use different functions or get your variables in a different way. I ran into this with the AnimInstance class, turned out there was an intended way for me to get the variables I needed that did work outside the Editor.
