Unable to Compile SDL Release Build

Question

despite the fact that I can compile a debug release fine, I'm unable to compile a release build. My linkage settings are fine yet I'm getting these strange errors.

Any ideas?

Did you add SDL2.lib and SDL2main.lib to Linker -> Input:Addition Dependencies for release configuration? — Unick, Aug 09 '14 at 11:01
Re-check the input to the linker and then take a look at MSDN: [Linker Tools Error LNK2001](http://msdn.microsoft.com/en-us/library/f6xx1b1z%28VS.80%29.aspx) — jpw, Aug 09 '14 at 11:04

This is most likely caused by not having set the library input for both configurations, a commonly made mistake. You just need to add the required libraries to the Release configuration. This also applies to the header file include directories
