c++ - 如何在 visual studio 2015 中显示 "unimplemented pure virtual"？

Question

我想像那样在 visual studio 2015 上显示这个警告/错误(在 clang 中):

/home/travis/build/x/x/src/guiComboBox.cpp:454:19: error: 

      allocating an object of abstract class type 'GUIListBox'

                m_listbox = new GUIListBox(Environment, this, -1, r, fal...

                                ^

/usr/include/y/IGUIListBox.h:88:16: note: unimplemented pure virtual

      method 'setItemOverrideColor' in 'GUIListBox'

                virtual void setItemOverrideColor(u32 index, const video...

                             ^

      method 'setItemOverrideColor' in 'GUIListBox'

                virtual void setItemOverrideColor(u32 index, EGUI_LISTBO...

我在 clang 中有这个错误，但在 visual studio 2015 中没有。有人可以帮助我吗？

Visual Studio 将显示以下错误:

class Abstract
{
  virtual void NotImplemented() = 0;
};

int main()
{
  // error C2259 : 'Abstract' : cannot instantiate abstract class
  // note: due to following members :
  // note: 'void Abstract::NotImplemented(void)' : is abstract
  // note: see declaration of 'Abstract::NotImplemented'
  Abstract* a = new Abstract();

  return 0;
}
