Dear advanced c++ programers:
I tried to copy and test a piece simple makefile code with
simple .cpp, .hpp code(s) which purpose is teach reader
how to use gnu make (especially on unix/linux) build (complex
application). That is the book (C++ Cookbook) chapter 1
example 1-2
1-3
1-20
1-22
1-23
1-24
-------------------------------------------------but it failed at
stage of make install (make TARGET=install)--------------
-------the following is after
make-------------------------------------------------------------------------------------------------------
eric@eric-laptop:~/cppcookbook/ch1$ ls
binaries georgeringo hellobeatles johnpaul Makefile
eric@eric-laptop:~/cppcookbook/ch1$ make TARGET=install

---------------------------------------------------------------------------------------
this is hellobeatles.cpp---------------------------------------
-----------------------------------------------
#include "johnpaul/johnpaul.hpp"
#include "georgeringo/georgeringo.hpp"
int main()
{
// Prints "John, Paul, George, and Ringo\n"
johnpaul();
georgeringo();
}
------------------------------------------------------------------------------
since my /hellobeatles directory after make, only produce
hellobeatles.d, but make TARGET=install demand
hellobeatles
which my directory don't have
the other examples codes mentioned in above(cpp,hpp,makefile) can be
found/download from
http://examples.oreilly.com/9780596007614/
or you have that book by yourself now.
I think mainly is Makefile in /hellobeatles cause error, but I have
no way(out of wit and experience) to fix it.
plz help
Eric
