SDK 2010.05 - 'Hallo world' doesn't work on Windows 7 64bit

[mastupristi]

I have installed SDK 2010.05 on windows 7 64bit.

then I try the simplest C source, the first example of every book that explain C language.

the hallo_world.c

#include <stdio.h>
int main(void)
{
  printf("hallo world\n");
  return 0;
}

#include <stdio.h>
int main(void)
{
  printf("hallo world\n");
  return 0;
}

To copy to clipboard, switch view to plain text mode 

No errors or warning in compilation (how can be?) but tring executing no string is output, neither on QT Creator's 'Application Output' windows nor on cmd console.

where I am wrong?

thanks
