Hi -
I know this isn't the perfect place for this posting but I am going
ahead with it anyway, as I havent gotten a lot of help googling, here it
is:
here is my compiler:

here is the output from compiling:

I refer to page:
http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/headers_cc.txt
which lists iostream as a standard library header. So why throw the
message from "backward/backward_warning.h" at me?
In addition, if I alter the #include to be
#include </usr/include/g++-3/iostream>
then I still get the "backward" warning, but note that I don't have to
put ".h" after the "iostream".
The goal here is to have a program reading:
#include <iostream>
int main(){
cout<<"Hello, world!"<<endl;
return 0;
}
compile without errors or warnings without having to add -Wno-deprecated
and using <iostream>, not <iostream.h> as iostream is supposed to be
compliant with the standard C libraries aforementioned.
P.S. - which libraries are best to use; /usr/include/g++-3/ or
/usr/include/c++/3.3/ ?
Any help or just comments are appreciated, thank
you.
