<DIV>> Hi ALL:</DIV>
<DIV>></DIV>
<DIV>> I want to use taglib to extract id3 from media files on wince 6.0. When I</DIV>
<DIV>> use VS2005 to build taglib , it have many the same warnings as the follow:</DIV>
<DIV>> /toolkit\tfile.h : warning C4251: 'TagLib::FileName::m_name' : class 'std::basic_string<_Elem,_Traits,_Ax>' needs to have dll-interface to be used by clients of class 'TagLib::FileName'</DIV>
<DIV>> 1> with</DIV>
<DIV>> 1> [</DIV>
<DIV>> 1> _Elem=char,</DIV>
<DIV>> 1> _Traits=std::char_traits<char>,</DIV>
<DIV>> 1> _Ax=std::allocator<char></DIV>
<DIV>> 1> ]</DIV>
<DIV>></DIV>
<DIV>> How to resolve this? Has it bad effect to my Application when I use it?</DIV>
<DIV>></DIV>
<DIV>> if I modify the class FileName to the followings:</DIV>
<DIV>></DIV>
<DIV>> class TAGLIB_API FileName</DIV>
<DIV>> {</DIV>
<DIV>> public:</DIV>
<DIV>> FileName(const wchar_t *name) : m_pwname(name) {}</DIV>
<DIV>> FileName(const char *name) : m_pname(name) {}</DIV>
<DIV>> operator const wchar_t *() const { return m_pwname; }</DIV>
<DIV>> operator const char *() const { return m_pname; }</DIV>
<DIV>> private:</DIV>
<DIV>> const char* m_pname;</DIV>
<DIV>> const wchar_t* m_pwname;</DIV>
<DIV>> };</DIV>
<DIV>></DIV>
<DIV>> ,the above warnings do not appear. But I don't know it is ok to use the</DIV>
<DIV>> Tablib.dll.</DIV>
<DIV></DIV>
<DIV>It isn't ok. The allocated memory might have been deleted in the</DIV>
<DIV>meantime. I think there are two possible options:</DIV>
<DIV></DIV>
<DIV> - Export the STL classes.</DIV>
<DIV> - Make it not require the exported classes. I think it complains</DIV>
<DIV>about the inline operators, so if we make these non-inline and compile</DIV>
<DIV>them into the DLL binary, it should probably go away.</DIV>
