boost :: property_tree編譯錯誤（錯誤C2061：語法錯誤：標識符'p'）

Question

我努力編譯一些利用boost屬性樹的代碼。我使用Visual Studio 2010中

如果我儘可能簡化代碼重現錯誤，代碼如下所示...

#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; 
} 

...和完整的錯誤外觀像下面...

對於我來說，我ApplieiTunesLibraryImporter.cpp文件的第24行只是

ptree pt; 

所以，編譯器不喜歡我使用它。我可以得到類似的錯誤，當我使用類似的東西

ptree::const_assoc_iterator assoc_iter; 

但上述代碼是最簡單的，我可以使錯誤發生。

導致編譯錯誤的boost文件（allocator_utilities.hpp）中的代碼如下所示，但對我來說很神祕。

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

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

如果有人想嘗試再現，這裏是.h代碼。

class AppleiTunesLibraryImporter 
{ 
public: 

    AppleiTunesLibraryImporter(); 
    virtual ~AppleiTunesLibraryImporter(); 

    bool ImportData(std::string itunes_library_xml_path); 

}; 

這一切都變成了一點腦融化，所以如果任何人都可以擺脫這一點，這將不勝感激。

乾杯。

我發現了這個問題。我正在處理的項目使用預編譯頭文件和使用boost庫的.cpp文件，因此我必須防止發生這種情況。換句話說，我必須右鍵單擊.cpp文件的去...

屬性>配置屬性> C/C++>預編譯頭

，並設置「預編譯頭」到「不使用預編譯頭」 此外，去...

屬性>配置屬性> C/C++>高級

並將「強制包含文件」設置爲空。
