I got this error when I was compiling SFML with Visual Studio, as both Debug and release, with the proper linking done and SFML_DYNAMIC added. I am using the Graphics and System Packages, but neither use nor link to the Window Package. here it is:
1>------ Build started: Project: Simple Rogue, Configuration: Release Win32 ------
