I receive the following 2 errors:

Looks like you have declared a GeoMap destructor, but not defined it.

[goosebumps4]

I have defined the constructor and the errors disappear, but then I encounter another problem: the application quits unexpectedly (I am presented with the usual pop-up window form Mac OS where I am given some info and the option to reopen).

@GeoMap::~GeoMap()
{
delete map;
delete coord;
delete mapScene;
delete mapView;
}@

[goosebumps4]

From what I can tell, form debugger mode, the problem seems to happen on this line

@ this->mapView->setScene(scene);
@

[goosebumps4]

I have done some small modifications in the constructor:

@GeoMap::GeoMap(QGeoMappingManager *mappingManager, QGraphicsView *view) : QGraphicsGeoMap(mappingManager)
{
this->coord = new QGeoCoordinate(45.783008, 24.148178);

// QGeoMappingManager *mappingManager = 0;
// QGeoServiceProvider serviceProvider("nokia");
// mappingManager = serviceProvider.mappingManager();
this->map = new QGraphicsGeoMap(mappingManager);

this->map->resize(350, 480);
this->map->setPos(1, 1);
this->map->setCenter(*coord);
this->map->setZoomLevel(15);

QGraphicsScene *scene = new QGraphicsScene;
scene->addItem(this->map);

// this->mapScene->addItem(this->map);

this->mapView = view;
this->mapView->setScene(scene);

// this->mapView->setInteractive(true);
}@

[ludde]

Looks like you are not creating your graphics view.

[goosebumps4]

Yeah ... I figured that could be the problem ... but I don't understand why?
When I move this pard in the main it works like a charm.
I even tried this:

@GeoMap::GeoMap(QGeoMappingManager *mappingManager, QGraphicsView *view) : QGraphicsGeoMap(mappingManager)
{
this->coord = new QGeoCoordinate(45.783008, 24.148178);

// QGeoMappingManager *mappingManager = 0;
// QGeoServiceProvider serviceProvider("nokia");
// mappingManager = serviceProvider.mappingManager();
this->map = new QGraphicsGeoMap(mappingManager);

this->map->resize(350, 480);
this->map->setPos(1, 1);
this->map->setCenter(*coord);
this->map->setZoomLevel(15);

QGraphicsScene scene;
scene.addItem(this->map);

// this->mapScene->addItem(this->map);

QGraphicsView vview(&scene);
vview.setInteractive(true);
vview.setVisible(true);

// vview.show();
this->mapView = &vview;
this->mapView->show();

// this->mapView = view;
// this->mapView->setScene(scene);
// this->mapView->setVisible(true);
// this->mapView->setInteractive(true);
}
@

[ludde]

Well, here you are creating a graphics view: @QGraphicsView vview(&scene);@
Before you didn't create one: @QGraphicsView *mapView;@
Just a pointer to one, which points to something arbitrary because you don't set its value.

Hi,
I am also facing the same problem on Same operating system.
I include the taglib with my project on windows and it is working fine on windows.
but when i try to run this on mac it give me the same error.
I add code in project.pro file:

@
INCLUDPATH +="taglib-1.6.3/include"
LIBS +="taglib-1.6.3/libtaglib.a"
LIBS +=taglib-1.6.3/taglib.dll
@

I already added libtaglib.a and taglib.dll in my project along with taglib source code.

I added code on Main:

@
#include "tag.h"
#include "fileref.h"
#include "taglib.h"
#include "taglib_export.h"

Q_DECL_EXPORT int main(int argc,char *argv[])
{
TagLib::FileName filepath("song.mp3");
TagLib::FileRef f(filepath);
TagLib::String artist=f.tag()->artist();
aDebug()<<"Artist="<< artist.toCString();
}
@

This code is working for windows but not for OSX.

[EDIT: code formatting, please wrap in @-tags]

[goetz]

you cannot use a .dll on a Mac. DLLs are Windows only.

Also, make sure to have the correct architectures for your executable. The Mac support so called universal binaries, that is code for multiple architectures (intel/ppc, 32/64 bit) in on big "fat" file.

Seems like your library is not built with x86_64 architecture.

[Jaswinder]

I compiled Taglib for Mac using cmake under this conditions
CMAKE_BUILD_TYPE=Release
CMAKE_OSX_ARCHITECTURE=x86_64
CMAKE_OSX_DEPLOYMENT_TARGET=10.6

I added in project.pro file
LIBS += taglib-1.6.3/taglib/libtag.1.6.3.dylib

When i build this project it crash on start and give me following error.

Thank you Volker with the help of your post i am able to solve this problem.

Hi,
I face some other problem with TagLib.
I compiled Taglib for Mac 10.6 using cmake under this conditions
CMAKE_BUILD_TYPE=Release
CMAKE_OSX_ARCHITECTURE=x86_64
CMAKE_OSX_DEPLOYMENT_TARGET=10.6
as in image
"Click Here for image":https://docs.google.com/document/d/1Hu_SGJuXSCANEZ4IsuhQP4VzLx6EonTgLWlkXgr4lP8/edit

Target folder : user/ngtech/desktop/taglibDy13
This is working fine on the source machine. But when i move the code on other MAC machine with same environment , i faced a error when i remove taglibDy13 folder from desktop.
library not loaded : /user/ngtech/desktop/taglibDy13/taglib/libtag.1.dylib.
I already copied required .dylib files in my project
@INCLUDEPATH +="taglib-1.6.3/include"
LIBS += "taglib-1.6.3/libtag.1.6.3.dylib"@

Can any one tell me how can i make this distributed library so that i can run my project on other computers.
