序列化聯盟類型：「靜態斷言失敗::而TYPEx ::值」

我從序列化的OpenCL的類型cl_long2這是這樣定義（自/usr/include/CL/cl_platform.hpp簡體）：我定義的序列化聯盟類型：「靜態斷言失敗::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;

以下獨立序列化功能：

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); 
} 

}};

當我編譯我的代碼，它調用cl_long2的系列化從作爲一個類的成員，我收到以下錯誤，我無法理解（錯誤是相同的，如果它不是std::vector<cl_long2>，只是一個獨立的變量）：無論存檔類型是XML或二進制

出現同樣的錯誤。我正在使用boost :: serialization 1.46。

任何提示？

通過任何機會，是「BOOST_NO_INTRINSIC_INT64_T」定義？ – LucasB 2012-03-20 09:57:22

不，它不是（我通過boost頭文件，而且它也不存在）。 'int64_t'是一個系統定義的類型（帶有gcc工具鏈的Linux）。 – eudoxos 2012-03-20 10:02:47

看着斷言行，它說「陷阱試圖序列化標記爲not_serializable的對象」。您應該查看http://www.boost.org/doc/libs/1_49_0/libs/serialization/doc/traits.html，尤其是出於某種原因爲您的數據類型設置的「not_serializable」屬性。 – LucasB 2012-03-20 10:28:04

如果你看看那裏的斷言失敗行（detail/check.hpp：60），也正上方評論：

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

documentation of this 'not_serializable' trait表示您必須先啓用此long2類型。正如你發現的，這是通過完成：

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