Answer 1

/usr/include/c++/5.1.1/cxxabi.h: At global scope:
/usr/include/c++/5.1.1/cxxabi.h:214:3: error: expected class-name before '{' token
   {
   ^
/usr/include/c++/5.1.1/cxxabi.h: In constructor '__cxxabiv1::__fundamental_type_info::__fundamental_type_info(const char*)':
/usr/include/c++/5.1.1/cxxabi.h:217:62: error: expected class-name before '(' token
     __fundamental_type_info(const char* __n) : std::type_info(__n) { }

这些表示以下代码行：

  class __fundamental_type_info : public std::type_info
  {
  public:
    explicit
    __fundamental_type_info(const char* __n) : std::type_info(__n) { }

不编译因为std::type_info不是类型。但是，由于<typeinfo>正好位于其上方，这导致我怀疑您的某个标题包含宏定义，如

#define type_info ...

（...可能为空）。

我建议检查预处理的来源。

其他数据点

以下代码在我的框中编译正确：

#include <boost/shared_array.hpp>
#include <set>
#include <string>
#include <vector>

#include <xercesc/dom/DOM.hpp>

namespace nsfocus {

struct FireWallRuleBase {};
struct Packet {};

class UrlRule : public FireWallRuleBase {
  private:
    std::set<int> m_cats;
    unsigned int m_url_action;
    bool CheckURLCat(Packet &p, std::string &category, boost::shared_array<unsigned short> &pCatID, unsigned short &nSize);

  public:
    UrlRule(void) : FireWallRuleBase(), m_url_action(0x4000) {}
    virtual ~UrlRule(void) {}
    virtual void Parse(xercesc::DOMNode *node);
    void ParseNoFwInfo(xercesc::DOMNode *node);
    void ParseFwInfo(xercesc::DOMNode *node);
    virtual bool isMatch(Packet &p, std::string &category, boost::shared_array<unsigned short> &pCatID,
                         unsigned short &nSize);
    virtual bool isProfileMatch(Packet &p, std::string &category, boost::shared_array<unsigned short> &pCatID,
                                unsigned short &nSize);
    unsigned int GetAction(void) { return m_url_action; }
};

} // namespace nsfocus
