Compiling 1.3.1 with G++ 4.8

[navijj]

We are seeing a compiler error with g++ 4.8 and would like some guidance. In particular it seems related to C++11 and enumerations.

Here is the slightly shortened compiler output.

C++11 enums are not supported out-of-the-box in RCF 1.3.1. C++11 enums are supported in RCF 2.0 using the SF_SERIALIZE_ENUM_CLASS macro.

If you can't upgrade, you can either write some custom serialization code of your own, or backport the SF_SERIALIZE_ENUM_CLASS macro. Try including this in your code:

Code: Select all

    
    template<typename T, typename U>
    inline void serializeAs(Archive & ar, T &t)
    {
        if (ar.isWrite())
        {
            U u = static_cast<U>(t);
            ar & u;
        }
        else
        {
            U u;
            ar & u;
            t = static_cast<T>(u);
        }
    }

#define SF_SERIALIZE_ENUM_CLASS(EnumType, BaseType)             \
    void serialize(SF::Archive & ar, EnumType & e)              \
    {                                                           \
        SF::serializeAs<EnumType, BaseType>(ar, e);             \
    }

, and then use SF_SERIALIZE_ENUM_CLASS , as described here:
