序列化联盟类型：“静态断言失败::而TYPEx ::值”

我从序列化的OpenCL的类型cl_long2这是这样定义（自/usr/include/CL/cl_platform.hpp简体）：我定义的序列化联盟类型：“静态断言失败::而TYPEx ::值”

typedef int64_t cl_long; 
typedef union 
{ 
    cl_long __attribute__ ((aligned(16))) s[2]; 
    struct{ cl_long x, y; }; 
    struct{ cl_long s0, s1; }; 
    struct{ cl_long lo, hi; }; 
} cl_long2;

以下独立序列化功能：

namespace boost{ namespace serialization { 
template<class Archive> void serialize(Archive &ar, cl_long2 &i, const unsigned version){ 
    ar & make_nvp("x",i.x); 
    ar & make_nvp("y",i.y); 
} 

}};

当我编译我的代码，它调用cl_long2的系列化从作为一个类的成员，我收到以下错误，我无法理解（错误是相同的，如果它不是std::vector<cl_long2>，只是一个独立的变量）：无论存档类型是XML或二进制

出现同样的错误。我正在使用boost :: serialization 1.46。

任何提示？

通过任何机会，是“BOOST_NO_INTRINSIC_INT64_T”定义？ – LucasB 2012-03-20 09:57:22

不，它不是（我通过boost头文件，而且它也不存在）。 'int64_t'是一个系统定义的类型（带有gcc工具链的Linux）。 – eudoxos 2012-03-20 10:02:47

看着断言行，它说“陷阱试图序列化标记为not_serializable的对象”。您应该查看http://www.boost.org/doc/libs/1_49_0/libs/serialization/doc/traits.html，尤其是出于某种原因为您的数据类型设置的“not_serializable”属性。 – LucasB 2012-03-20 10:28:04

如果你看看那里的断言失败行（detail/check.hpp：60），也正上方评论：

// trap attempts to serialize objects marked 
// not_serializable 
BOOST_STATIC_ASSERT(typex::value);

documentation of this 'not_serializable' trait表示您必须先启用此long2类型。正如你发现的，这是通过完成：

BOOST_CLASS_IMPLEMENTATION(long2,boost::serialization::object_serializable)
