About inconsistent dll linkage

Question

How can I remove this link warning? You can see code segment that causes this warning.

static AFX_EXTENSION_MODULE GuiCtrlsDLL = { NULL, NULL };
//bla bla
//         


        

Answer 1

There are multiple possibilities:

1) static AFX_EXTENSION_MODULE GuiCtrlsDLL = { NULL, NULL };

You use AFX_EXTENSION_MODULE. This means that you are implementing an MFC extension DLL. For such extension dlls you have to define the preprocessor _AFXEXT. Set this in the C++ compiler settings of your Visual C++ project

2) It is likely that you have a duplicated definiton/declaration.
