make: implicit rule to link c++ project

Question

I am working my way through a make tutorial. Very simple test projects I am trying to build has only 3 files: ./src/main.cpp ./src/implementation.cpp and

Answer 1

The implicit rule for linking object files is:

$(LINK.o) $^ $(LOADLIBES) $(LDLIBS) -o $@

But $(LINK.o) uses $(CC), which is not quite correct for compiling C++ programs, so the easiest fix is:

CC = $(CXX)
