How do I enable the 6000 series warnings (code analysis warnings) in MSVC++?

Question

Even warning level 4 and \"all warnings\" does not make the 6000 series warnings appear.

Answer 1

Actually enabling these "Code Analysis" warnings has it's own dialog.

In your project properties, you must check "Enable Code Analysis on Build" to make it work.

This code should then show error 6246:

#include 

int main()
{
  int x ;

  {
    int x = 6 ;
    printf( "%d\n", x ) ;
  }

}

warning C6246: Local declaration of 'x' hides declaration of the same name in outer scope.

This setting appears to be completely independent of the "Configuration Properties/C/C++/General/Warning Level" setting in the properties dialog.
