Hi,

There is no problem to compile a C source for my GCC. The file below
was compiled without problem :

#include <stdio.h>
int main() {
  printf("Hello World\n");
} 

But it doesn't work with this one :

#include <iostream>
int main() {
  int x;
  cin >> x;
  cout << "Hello, World! I am " << x << " Today!" << endl;
}

After executing "redir -o gcc.log -eo gcc -v ccaa.cc", the contenent
of gcc.log is :

How can I do to make it work?
Thanks.
