g++ 3.1.1 issue

[Dmitry Kostenko]

I've downloaded & installed gcc 3.1.1 from
gcc.gnu.org, it compiled OK but I've got a problem:
gcc does compile c++ sources but is not
autoconfigured to find STL include headers.
for example, such main.C will compile:
int main()
{  return 0; }

and such file won't:

#include <iostream>
int main()
{
  std::cout << "Hello, World!\n";
  return 0;
}

when I say gcc main.C, it says <iostream>
not found, and std is not a namespace...

I've search to installation guide, it
doesn't say much about such problem.
Where to find documentation on gcc configuration.

Did you mean `g++ main.C'?

'gcc main.C' should still work.  The difference between gcc and g++ really
doesn't matter until you get to the linking stage.  If the user is on a
case-insensitive filesystem, where main.C could be interpreted as main.c,
then there would e a difference there as well.

OK. I'll tell everything from the beginning, because I see
my first letter was quite ... messy :)))

I have a Linux Slackware 8.0 system and I've downloaded, compiled
and installed GCC 3.1.1 + G++ on it. Everything was OK. Until I tried to
compile QT 3.0.4. It failed, saying it couldn't find C++ STL headers. They are
in place, but gcc doesn't look for them automatically when compiles C++ files
(.C, .cc, .cpp, .c++).
So if I compile a C++ file without any reference to STL (or libstdc++),
everything goes OK, but it I try to compile a simple hello world, it fails. For
example I write main.cpp:

#include <iostream>
#include <iomanip>

int main()
{
  std::cout << "Hello, World!" << std::endl;

}

And then issue a command:
$ gcc main.cpp
I fails to compile and says, it can't find iostream and iomanip.

The question is How to config gcc to search for standrard headers
automatically?

GCC already searches for these headers automatically, unless it has been
misinstalled.  Please give your configuration line, and the output of "gcc -v",
and the exact error message you're seeing.

Everything is OK already... I really
have misinstalled gcc. I've corrected that.
Thank you for help :)
