Cheers people. I had the same problem with SFML 2.2. Adding GLEW_STATIC helped with my x64 build where I need to link glew.lib only. For the x86 one, strangely I need to link glew32.lib AND glew.lib to compile without warnings, yet still have dynamic linkage with GLEW_STATIC (i.e. get missing dll error for glew32.dll on load). I'm still checking my properties to make sure I haven't missed anything. Using MSVC 2010.
