Compiler Error C2492
Visual Studio 2008
'variable' : 'thread' data may not have dll interface
The variable is declared with the thread attribute and with the DLL interface. The address of the thread variable is not known until run time, so it cannot be linked to a DLL import or export.
The following sample generates C2492:
// C2492.cpp
// compile with: /c
class C {
public:
char ch;
};
__declspec(dllexport) __declspec(thread) C c_1; // C2492
__declspec(thread) C c_1; // OK
