This is obviously an issue with the linker so you have to find out how you
tell Eclipse to tell gcc (and hence ld) about the libraries.

It all works -- using the supplied Makefile. You chose not to use it, you
need to 'port' it to your preferred build tool.

The relevant lines are

LDLIBS := 		$(RLDFLAGS) $(RRPATH) $(RBLAS) $(RLAPACK) $(RCPPLIBS) $(RINSIDELIBS)

as well as all the lines filling the variables uses here.  When I build first
example, it ends up being (and note that paths etc depend on local
installations)

You could always use make if the Eclipse build tool cannot be tamed...
