I have a Visual C++ DLL project (just a project, without parent solution) and need to build the DLL.

Build command doesn’t generate any error messages. In the Debug folder there is mylibrary.lib, but no mylibrary.dll.

I looked at Visual Studio 2010 C++ DLL project – No output DLL file!, but my case differs from that question. In the build output, there is no message like

MFCInterop.vcxproj -> C:\temp\sotest\Debug\MFCInterop.dll

only

MFCInterop.vcxproj -> C:\temp\sotest\Debug\MFCInterop.lib

What can I do in order to generate the DLL file?

    It may happen if your DLL does not expose anything.
    Normally public API classes of your DLL should be exposed using following construction:

    #ifdef YOUR_DLL_EXPORTS
    #define YOUR_API __declspec(dllexport)
#else
    #define YOUR_API __declspec(dllimport)
#endif 

class YOUR_API ClassToExpose {};

    Then you have to define YOUR_DLL_EXPORTS inside DLL project.
    If you don’t have exposed stuff DLL is not generated. I hope this helps.
