C++ boost:：属性树编译错误（错误C2061：语法错误：标识符'；p'；）

我正在努力编译一些使用boost属性树的代码。我正在使用VisualStudio2010

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;
}

因此，编译器不喜欢我使用它。当我使用类似于

ptree::const_assoc_iterator assoc_iter;

但是上面的代码是我能使错误发生的最简单的代码

导致编译错误的boost文件（allocator_utilities.hpp）中的代码如下所示，但对我来说它相当神秘

/* allocator-independent versions of construct and destroy */

template<typename Type>
void construct(void* p,const Type& t)
{
  new (p) Type(t);
}

这一切都变成了一点大脑的融化，所以如果有人能对此有所了解，我们将不胜感激

干杯。

我找到问题了。我正在处理的项目使用了预编译的头文件，对于使用boostlibs的.cpp文件，我必须防止这种情况发生。换言之，我必须右键单击.cpp文件并继续

属性>配置属性>C/C++>预编译头

并将“预编译头”设置为“不使用预编译头” 还有，去

属性>配置属性>C/C++>高级

---

并将“强制包含文件”设置为“无”。

我也有类似的问题，因为上面的解决方案不适用于我。我必须找到根本原因。当我发现这让我恼火时，我意识到这不是我第一次做这个调查：）。因此，这次没有错误，并在此处记录根本原因：）。 我怀疑这和作者的根本原因是一样的。 所以在我的例子中，问题是在作为预编译头的一部分包含的头中的某个地方

#define new .... // Debugging memory leaks in debug

这个通过预编译头的定义将新的位置搞乱了

因为抛弃这个定义是有问题的（“政治”原因）。在我的案子里我能找到的最好的办法

#pragma push_macro("new")
#undef new
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/info_parser.hpp>
#pragma pop_macro("new")

#pragma push_宏（“新”）
#未定义新
#包括
#包括
#pragma pop_宏（“新”）

我需要更多的代码-不要发布部分错误消息和部分代码，而是将您的问题归结为您可以发布完整代码的内容，以便我们可以重现错误。感谢您的回复，Zac。你说得对，我遗漏了一些有用的信息，所以我编辑了原始帖子，使其更加完整。谢谢。您应该尝试在不添加任何内容的情况下重现此问题，并提供一个可编译的代码段来重现此问题。对我来说，在gcc和boost 1.49I上工作得非常完美。我在mac（gcc 4.0）和LLVM上的代码编译非常好。是窗户让我伤心。通过“添加”，您是指xml_解析器的使用吗？

#define new .... // Debugging memory leaks in debug

#pragma push_macro("new")
#undef new
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/info_parser.hpp>
#pragma pop_macro("new")
