taglib with mingw on eclipse with qt integration

[passive]

hi, i'm trying to write a project that uses taglib to read tags from music files, i've been trying all day to get taglib working right but i'm failing miserably..
i got the binary builds of taglib from http://developer.kde.org/~wheeler/taglib.html#windows and when i try to use it as:

	TagLib::FileRef f("e:\\file.mp3");
	cout << f.tag()->artist();

it says:

Severity and Description Path Resource Location Creation Time Id
C:/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../include/tfile.h forward declaration of `struct TagLib::Tag' test line 36 1206167176078 8


what's the problem here? i'm trying to compile from eclipse cdt with mingw and qt integration.

thank you..
