LIBS := -laudiere -lNewton -lOgreMain -lOIS

and i an a new linux,eclips user...

thank you

Is that the only information the linker gives you? It's possible that it can't find the file it's looking for. You can try putting libOgreNewt.so in your /usr/lib directory. You can use this command in terminal:
$ sudo cp /path/to/library/file/libOgreNewt.so /usr/lib

Also, you shouldn't be editing the makefile with eclipse unless you know what you're doing. and If it compiles without linking with libOgreNewt than, you don't use any code from OgreNewt so you don't need it now anyways.
