First of all: You do not have to compile the arduino library. Eclipse takes care of that. It doesn't matter if you do ant it should compile.
However:
Secondly: You claim that the arduino library doesn't compile and you give me an image that shows a file "liquidcrystal.cpp" which is not part of your project nor part of the arduino library. Where does this file come from?
Are you trying to waist my time?
