Full Discussion: Simple Makefile Problem (with a dependency)

You need to think about what the chain of dependencies really are:

The executable Code1 depends on the object files Code1.o and Tools.o
The object file Code1.o depends on the source files Code1.cpp and Tools.hh and the makefile
The object file Tools.o depends on the source files Tools.cpp and Tools.hh and the makefile.

So a simple makefile could be something like
Code:
%.o: %.c Tools.hh makefile

Code1: Code1.o Tools.o
Code2: Code2.o Tools.o
Code3: Code3.o Tools.o

This uses
- a pattern rule to say that any .o depends on the corresponding .cpp and the header and the makefile
- rules to say that Code1 depends on Code1.o and Tools.o
- implicit rules to do the compilation and linking (make knows it needs to use g++ to compile, and so on)

If you want to specify the compilation or linking rules yourself, then you have to specify the complete command. You had
Code:
Code3: $(TOOLSRC) $(TOOLSINC) makefile
                $(CXX)

where your rule is just "g++" with no arguments. That's like typing just g++ on the command line, hence the error message, You need to have the same thing as you would type on the command line, e.g.
Code:
        $(CXX) Code3.o Tools.o -o Code3

or if you want to be fancy and more general with automatic variables
Code:
        $(CXX) $^ -o $@

NAME

       Participants and synchronization sources. -

   Classes
       class SDESItemsHolder
           Holds the SDES items and related information from a participant in an RTP application.
       class Participant
           A class of objects representing remote participants (RTP applications) in a multimedia session.
       class SyncSource
           Synchronization source in an RTP session.
       class RTPApplication
           An RTP application, holding identifying RTCP SDES item values.

   Functions
       __EXPORT RTPApplication & defaultApplication ()
           Get the RTPApplication object for the 'default' application (the only one used by common applications -those that only implement one
           'RTP application').

Detailed Description
Function Documentation
   __EXPORT RTPApplication& defaultApplication ()
       Get the RTPApplication object for the 'default' application (the only one used by common applications -those that only implement one 'RTP
       application'). Note that this application object differs from all the others that may be defined in that it is automatically constructed by
       the ccRTP stack and its CNAME is automatically assigned (as user@host), whereas the other application objects' CNAME is provided to its
       constructor.

       Examples:
           ccrtptest.cpp, rtphello.cpp, rtplisten.cpp, and rtpsend.cpp.
