Thread-topic: problem in getting WString Attribute
XMLCh and wchar_t are not synonymous under Xcode; XMLCh is 16 bits wide, typedef'd from unsigned short, while wchar_t is 32 bits wide. Since getAttribute returns a const XMLCh*, this shouldn't even be compiling (std::wstring doesn't have a constructor that matches XMLCh*). Unless, of course, you've changed wchar_t to be a short with -fshort-wchar, in which case you have to provide all the wchar_t library functions yourself (which may explain the app termination problem if you're weak-linking against those functions; you're trying to call unresolved symbols).
Another approach is to typedef something like this:
#if TARGET_OS_MAC
typedef UniChar utf16char;
typedef std::basic_string<UniChar> utf16string;
#elif _WIN32
typedef wchar_t utf16char;
typedef std::wstring utf16string;
#endif
And use utf16char/utf16string everywhere instead of explicitly referencing wchar_t and std::wstring. I believe UniChar and XMLCh are synonymous under Xcode (both are unsigned shorts).
