Simple Makefile Problem (with a dependency)
Hi all,

I have 4 '.cpp' files and 1 header files:


Code:
Tools.cpp
Code1.cpp
Code2.cpp
Code3.cpp

and Tools.hh

Now all
Code:
Code1.cpp, Code2.cpp, Code3.cpp

use functions stored in
Code:
Tools.cpp

.

Currently, what I do to compile all of them is using
this simple shell script:

Code:
#!/bin/bash
echo "compiling Code1.cpp";
g++ Code1.cpp Tools.cpp -o Code1

echo "compiling Code2.cpp";
g++ Code2.cpp Tools.cpp -o Code2 

echo "compiling Code3.cpp";
g++ Code3.cpp Tools.cpp -o Code3

It all works fine.

Now I want to do that using a standard makefile.
But why this doesnt' work:

Code:
XX = g++

TOOLSRC = Tools.cpp Code1.cpp Code2.cpp \
Code3.cpp    

TOOLSINC = Tools.hh      

all: Code1 Code2 Code3

Code1: $(TOOLSRC) $(TOOLSINC) makefile
                $(CXX)   

Code2: $(TOOLSRC) $(TOOLSINC) makefile
                $(CXX)   

Code3: $(TOOLSRC) $(TOOLSINC) makefile
                $(CXX)


The error I got is this:
Code:
g++
i686-apple-darwin9-g++-4.0.1: no input files
make: *** [Code1] Error 1

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.
