Hi Eric

No problem, I've fixed this, it can be closed

using static_case will work in Windows/Mac/Linux

ObjectHandler::property_t propertyVar =

        ObjectHandler::property_t(static_cast<long>longTypeVar)

Apologies for the delay in getting back to you.  I will try to be
quicker with any follow up.

Above the line of boost code which fails to compile, I find the
following comment:

        // NOTE TO USER :
        // Compile error here indicates that the given type is not
        // unambiguously convertible to one of the variant's types
        // (or that no conversion exists).

But based on the info you provided I don't see why that error occurs.
If the variable called longTypeVar was declared with type long then I
would not expect that error.  Can you provide more information?

Kind Regards,
Eric
