This question should have been sent to gcc-help, not here.

But as long as I'm answering:

It's std::cout now, according to the C++ standard.
If you want to compile old code that wasn't aware of std,
you can stick
  using namespace std;
at the top.

Sorry about this. What criteria is there for posting to gcc vs gcc-help?

Thanks for answering, I forgot to mention that I did try adding the 
namespace prefix and also the "using" statement and I get the same error. 

Thank you

If you want to contribute to the source code of gcc, the compiler, then 
those contributions go to gcc.  If one is using gcc, those issues go to 
gcc-help.

GCC 4.0.1 - iostream: No such file or dir....

[Chris Garrett]

I finally got 4.0.1 built in msys. I must have screwed up my msys/gcc 
setup because a clean install of msys and gcc-3.4.1 worked. I started 
with a simple test:

main.cpp:
~~~~~~~~~~~~~~~~~~~~~~~~~~
#include <iostream>

int main()
{
        cout << "Hello\n";
        return 0;
}


then I try and build it:
~~~~~~~~~~~~~~~~~~~~~~~~~~
chris@NEPTUNE /d/tmp/simple$ g++ main.cpp -o main
main.cpp:1:20: error: iostream: No such file or directory
main.cpp: In function 'int main()':
main.cpp:5: error: 'cout' was not declared in this scope

I looked thru in /mingw/include/c++/4.0.1 and iostream exists in that 
directory. Is there something I'm missing? Do you need to specify gcc's 
include directories explicitly now?

Thank you

Chris
