How to use TagLib into my Qt c++ Project

Punit

Hello,

I'd like to get the additional information of a media file in a qt application i'm building and so i decided to use taglib. Can anyone tell me how to use TagLib in qt from the beginning ? The version I got was 1.6.3.

Thanks

Hi,

If you mean add that library to your Qt project, you can follow that guide for Qt Creator.

I have no idea what to do with it or add which file to my app. can you please explain how to build it?
What I did so far:
(Currently working on mac but want it for both Windows and mac).

Download TagLib-1.6.3.

Now using terminal:
cd /Taglib-1.6.3
./configure
make
sudo make install

A default build and install. So, the configure prefix was /usr/local. But there is no .a file in my lib folder. Please guide me with necessary steps to build and use Taglib in my qt Project.

After searching, I found a solution.

$ cd taglib-1.6.3

$ cmake -DCMAKE_BUILD_TYPE=Release
-DCMAKE_OSX_DEPLOYMENT_TARGET=10.6
-DCMAKE_OSX_ARCHITECTURES="i386;x86_64"
-DENABLE_STATIC=ON
-DCMAKE_INSTALL_PREFIX="/Users/macwaves/Desktop/lib2"

$ make

$ sudo make install

Now I have "libtag.a" inside my lib folder (/Users/macwaves/Desktop/lib2/lib) and about 75 header files inside "/Users/macwaves/Desktop/lib2/include/taglib".

I have created a project and then open .pro file, right click ( just in middle of file)
and choose "Add library", then browse to the .a file.

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../../Users/macwaves/Desktop/lib2/lib/release/ -ltag
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../../Users/macwaves/Desktop/lib2/lib/debug/ -ltag
else:unix: LIBS += -L$$PWD/../../../../Users/macwaves/Desktop/lib2/lib/ -ltag

INCLUDEPATH += $$PWD/../../../../Users/macwaves/Desktop/lib2/include/taglib
DEPENDPATH += $$PWD/../../../../Users/macwaves/Desktop/lib2/include/taglib

win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/../../../../Users/macwaves/Desktop/lib2/lib/release/libtag.a
else:win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/../../../../Users/macwaves/Desktop/lib2/lib/debug/libtag.a
else:win32:!win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/../../../../Users/macwaves/Desktop/lib2/lib/release/tag.lib
else:win32:!win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/../../../../Users/macwaves/Desktop/lib2/lib/debug/tag.lib
else:unix: PRE_TARGETDEPS += $$PWD/../../../../Users/macwaves/Desktop/lib2/lib/libtag.a

Now In my mainwindow.h

#include <QMainWindow>
#include <fileref.h>
#include <tag.h>

and mainwindow.cpp

TagLib::FileRef f("/Users/macwaves/Desktop/Testing/my.mp3",true);

but it's generating errors.
:-1: error: symbol(s) not found for architecture x86_64
:-2: error: linker command failed with exit code 1 (use -v to see invocation)

Please help me ! Thanks

Since your on Linux, why not install the taglib devel package from your distribution ?
