我正在努力编译一些使用boost属性树的代码。我正在使用Visual Studio 2010。
如果我尽可能地简化代码以重现错误，则代码如下所示......
#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。当我使用像
这样的东西时，我会遇到类似的错误ptree::const_assoc_iterator assoc_iter;
但上面的代码是最简单的我可以使错误发生。
导致编译错误的boost文件（allocator_utilities.hpp）中的代码如下所示，但它对我来说非常神秘。
/* allocator-independent versions of construct and destroy */
template<typename Type>
void construct(void* p,const Type& t)
{
new (p) Type(t);
}
如果有人想尝试重现，这里是.h代码。
class AppleiTunesLibraryImporter
{
public:
AppleiTunesLibraryImporter();
virtual ~AppleiTunesLibraryImporter();
bool ImportData( std::string itunes_library_xml_path );
};
这已经变成了一些大脑融化，所以如果有人能够对此有所了解，那将非常感激。
干杯。

我发现了问题。我正在处理的项目使用预编译的头文件和使用boost库的.cpp文件，我必须防止这种情况发生。换句话说，我必须右键单击.cpp文件... ...
属性＆gt;配置属性＆gt; C / C ++＆gt;预编译标题
并将“预编译标题”设置为“不使用预编译标题” 另外，去......
属性＆gt;配置属性＆gt; C / C ++＆gt;先进
并将“强制包含文件”设置为空。

我有类似的问题，因为上述解决方案不适用于我。我必须找到根本原因。当我感到烦恼时，我意识到这不是我第一次进行这项调查：)。所以这次没有错误，并在这里记录了根本原因:)。 我怀疑这与作者产生的根源相同。 因此，在我的情况下，问题是在预编译的标头中包含的标头中某处有
#define new .... // Debugging memory leaks in debug
通过预编译头文件获得的此定义将新的位置拧紧。
由于放弃此定义是有问题的（“政治”原因）。在我的情况下找到最好的方法
#pragma push_macro("new")
#undef new
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/info_parser.hpp>
#pragma pop_macro("new")
