[SCALUG] Re: c++ question

[John Burski]

My thanks to those who responded to my question -- I really appreciate 
the help.

However, my problem still remains.

Since I received multiple suggestions and I didn't want to discount any, 
I created two different source files, "hello0.cpp" and "hello1.cpp" 
(sources files are attached).  I then created "Makefile[123]" for 
compiling and linking "hello0.cpp" and "Makefile[456]" for compiling and 
linking "hello1.cpp" (files are attached).

I executed each "Makefile" in turn, the results of which are in the 
corresponding "make?.txt" files.

As you can see, when I used "namespace std" I still received results 
that seemed to indicate that the appropriate link library was not 
included.  When I used "std::cout" the results indicated that "cout" was 
not declared.

While I was writing this,  another thought occured to me, so I created 
"hello2.cpp" and "Makefile7", the results of which are in "make7.txt". 
 Still no joy.

I know I've got to be missing something, but I'm still at a loss for 
what it might be.

Thanks again.
