<DIV>
<DIV> </DIV>
<DIV style="TEXT-INDENT: 2em">I want to use taglib to extract id3 from media
files on wince 6.0. When I use VS2005 to build taglib , it have many the same
warnings as the follow:</DIV>
<DIV style="TEXT-INDENT: 2em">
<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> </DIV>
<DIV>How to resolve this? Has it bad effect to my Application when I use
it?</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>if I modify the class FileName to the followings:</DIV>
<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>
<DIV>,the above warnings do not appear. But I don't know it is ok to use the
Tablib.dll.</DIV>
<DIV> </DIV>
<DIV>As we know, MSVC has many options to build the library, such as
UNICODE(Preprocessor Definitions), treat wchar_t as build in type, Runtime
library...</DIV>
<DIV> </DIV>
<DIV>What should we select?</DIV>
<DIV> </DIV>
<DIV>I am a newer to use the taglib and not familiar to MSVC, so I want to
have someone to help me.</DIV>
