I'm not clear on why I get that error on this piece of code:

#include "stdafx.h"

class A {
public:
      static bool myvar;
};

int _tmain(int argc, _TCHAR* argv[])
{
      A::myvar = true;
      return 0;
}

Thanks!

#include "stdafx.h"

class A {
public:
      static bool myvar;
};

bool A::myvar;


int _tmain(int argc, _TCHAR* argv[])
{
      A::myvar = true;
      return 0;
}

Open in new window


you have declared the bool, but didn't define it. (added line 8)
