boost：:p roperty_tree 编译错误(错误 C2061：语法错误：标识符"p")

>我正在努力编译一些利用提升属性树的代码。我正在使用Visual Studio 2010。

如果我尽可能简化代码以重现错误，代码如下所示...

#include "AppleiTunesLibraryImporter.h"
#include <boost/property_tree/xml_parser.hpp>
#include <boost/property_tree/ptree.hpp>
using namespace boost::property_tree;
AppleiTunesLibraryImporter::AppleiTunesLibraryImporter(){}
AppleiTunesLibraryImporter::~AppleiTunesLibraryImporter(){}
bool AppleiTunesLibraryImporter::ImportData( std::string itunes_library_xml_path )
{
    ptree pt;
    xml_parser::read_xml( itunes_library_xml_path.c_str(), pt, xml_parser::no_comments | xml_parser::trim_whitespace);
    return true;
}

。完整的错误如下所示...

对我来说，我的ApplieiTunesLibraryImporter.cpp文件的第24行只是

ptree pt;

所以，编译器不喜欢我使用它。当我使用类似的东西时，我可能会遇到类似的错误

ptree::const_assoc_iterator assoc_iter;

但是上面的代码是我可以使错误发生的最简单的代码。

导致编译错误的提升文件（allocator_utilities.hpp）中的代码如下所示，但对我来说非常神秘。

/* allocator-independent versions of construct and destroy */
template<typename Type>
void construct(void* p,const Type& t)
{
  new (p) Type(t);
}

如果有人想尝试复制，这里是 .h 代码。

class AppleiTunesLibraryImporter
{
public:
    AppleiTunesLibraryImporter();
    virtual ~AppleiTunesLibraryImporter();
    bool ImportData( std::string itunes_library_xml_path );
};

这一切都变成了一点大脑融化，所以如果有人能对此有所了解，将不胜感激。

干杯。
