I can only point you again to the
FAQ.
Eclipse uses GCC thus the libraries to link won't have an *.lib extensions, but *.a, however when specifying libraries for GCC, you don't include the extensions, but instead just write: sfml-graphics, winmm, glew, etc
The linker will then automatically search for winmm.a or libwinmm.a etc.
You should really learn how to use your tools (Eclipse, linker, compiler, etc).
