    Added the Tobii library at C++ and compiled the example source.
    However, the error will be output as shown below.

    “class IL::InteractionLib * __cdecl IL::CreateInteractionLib(enum IL::FieldOfUse)” (?CreateInteractionLib@IL@@YAPAVInteractionLib@1@W4FieldOfUse@1@@Z)
    Failed to verify the external symbol (reference location: _main function).

    “void __cdecl IL::DestroyInteractionLib(class IL::InteractionLib *)” (?DestroyInteractionLib@IL@@YAXPAVInteractionLib@1@@Z)
    Failed to check external symbol (reference location: “public: void_thiscall IL::InteractionLibDelter:()class IL::InteractionLib *”) (?RInteractionLibDeleter@IL@QAEXPAPAVPAVPACTIONInactiveZ)

    Two unverifiable external references.

    How can I fix it?

    Hi @code1995, sorry to hear about your issues. Prior to creating an error report, Could you kindly clarify for us the exact SDK/ API binding and version you are using (we have several Tobii C++ SDK’s) along with a description of your development environment (IDE, OS, etc) and relevant versions thereof. The more detail the better.

    Thereafter, we should hopefully be better placed to provide you with a prompt resolution on the error. Many thanks for your patience.
