    };



    template<Color C, GenT GT>
    // Generates all pseudo-legal moves of color for targets.
    INLINE ValMove* generate_moves (ValMove *&m_list, const Position &pos, Bitboard targets, const CheckInfo *ci = NULL)

        // ERROR :: generate<C>
        // error: no match for 'operator<' (operand types are '<unresolved overloaded function type>' and 'Color'
        // for ALL CALLS TO  generate<C>

        if (EVASION != GT)
        {
            Generator<GT, KING>::generate<C> (m_list, pos, targets, ci);
        }

        return m_list;
    }

}

make.exe -f MakeFile build ARCH=x86-32 COMP=mingw

为什么会出现这个错误？我正在使用minGW进行编译。

error: no match for 'operator<' (operand types are '<unresolved overloaded function type>' and 'Color'

请解释一下，我在这里提供了完整的代码。

将template放在generate功能的generate_moves前面。例如：

Generator<GT, PAWN>::template generate<C> (m_list, pos, targets, ci);

编译器识别generate是函数类型，但不知道您想将名称视为模板。因此，它将<后面的{{1}}视为小于运算符，导致您看到的错误。

错误：'operator＆lt;'不匹配（操作数类型为'<unresolved overloaded =“”function =“”type =“”>'和'Color'）</unresolved>
