I just want to read ID3 tags from mp3s, but it is becoming a real pain.

I'm trying to use taglib, and I have
Code: 
#include </usr/local/include/taglib/tag.h>
#include </usr/local/include/taglib/fileref.h>
and then comping I get
Code: 
g++ -c -pipe -g -gdwarf-2 -Wall -W -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/local/Qt4.5/mkspecs/macx-g++ -I. -I/Library/Frameworks/QtCore.framework/Versions/4/Headers -I/usr/include/QtCore -I/Library/Frameworks/QtGui.framework/Versions/4/Headers -I/usr/include/QtGui -I/usr/include -I. -I. -F/Library/Frameworks -o mainwindow.o mainwindow.cpp

i tried id3lib, placed
Code: 
#include <id3/tag.h>
and then
Code: 
ID3_Tag myTag( "testing.mp3" );
and I get
Code: 
g++ -c -pipe -g -gdwarf-2 -Wall -W -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/local/Qt4.5/mkspecs/macx-g++ -I. -I/Library/Frameworks/QtCore.framework/Versions/4/Headers -I/usr/include/QtCore -I/Library/Frameworks/QtGui.framework/Versions/4/Headers -I/usr/include/QtGui -I/usr/include -I. -I. -F/Library/Frameworks -o mainwindow.o mainwindow.cpp

so does anyone know of any other libraries I could try? Pref. something simple with just a header+source file. I tried a couple of old ones written in C, but they didn't work either.

Have you found the missing headers that taglib is complaining about? That might clear up the rest of the errors.
 
well, its not that they're missing, but if i change the fileref.h's includes from
Code: 
#include <tfile.h>
#include <tstringlist.h>
to
Code: 
#include "tfile.h"
#include "tstringlist.h"
I don't get the not found error, but then I get
Code:

And I have no idea what those errors mean/how to fix it.
