Symbol(s) not found for architecture x86_64

thisaintme

Hi,

first of all I'd like to say that I know that there's already a thread open on that topic in which I posted as well. But since I didn't get any reply until now and as it's quite urgent I try my luck opening up a new topic on the same problem.
I’m using Qt 4.7.3 on my Mac (OS X.6.7).
I tried to run my project from Qt Creator and from eclipse but I keep getting the above mentioned error message.

Background: I need to implement a few functionalities into a given framework that wasn’t created by myself.
As the framework is quite large, I think it’s not useful to post it here. And as the above mentioned problem could be solved by modifying the pro-file I think that’s where my problem might be as well.

So here’s my pro-file:
@#-------------------------------------------------

Project created by QtCreator 2011-06-17T13:45:15

I made a few modifications according to the sampe pro file posted in this thread:
"http://developer.qt.nokia.com/forums/viewthread/5665/":http://developer.qt.nokia.com/forums/viewthread/5665/

Yet I get this error message:
error: symbol(s) not found for architecture x86_64

If you need any further information, please let me know.

Thanks a lot in advance.

I do not have a solution however I am having a similar problem, I made a post here http://developer.qt.nokia.com/forums/viewthread/7168/ however I probably should have put it in this tools group as you did.

A suggestion is to try:

lipo -info yourlib.a
and make sure it is also x86_64

and the second is to see if the symbols not found are mentioned in the lib, try:

nm yourlib.a | grep the_symbol_without_args

You can see my post for an example.

If both of those pass the test then you are at the same point I am. With any luck we can solve this and move on to actual development. :)

As a follow up, where are libssl and libcrypto coming from?

The linker will tell you which symbol is missing. That will help you to find out what differs.

Please show the complete output of the linker. You will find it in Qt Creator on the compiler output tab.

Hello,
I'm prompted with the same kind of errors :

@# Add files and directories to ship with the application

by adapting the examples below.

file1.source = myfile

dir1.source = mydir

DEPLOYMENTFOLDERS = # file1 dir1

symbian:TARGET.UID3 = 0xEDF1E0C2

Smart Installer package's UID

This UID is from the protected range

and therefore the package will fail to install if self-signed

By default qmake uses the unprotected range value if unprotected UID is defined for the application

and 0x2002CCCF value if protected UID is given to the application

#symbian:DEPLOYMENT.installer_header = 0x2002CCCF

Allow network access on Symbian

symbian:TARGET.CAPABILITY += NetworkServices

If your application uses the Qt Mobility libraries, uncomment

the following lines and add the respective components to the

MOBILITY variable.

CONFIG += mobility
MOBILITY += location

CONFIG += x86_64
CONFIG -= i386
LIBS += -lssl -lcrypto
SOURCES += main.cpp
mapswidget.cpp
mapswidgetprivate.cpp
geomap.cpp
HEADERS +=
mapswidget.h
mapswidgetprivate.h
geomap.h
FORMS += mainwindow.ui

Please do not modify the following two lines. Required for deployment.

include(deployment.pri)
qtcAddDeployment()

The linker usually shows you which symbol(s) is/are missing. There should be more output from the error message.

It's hard to tell what's going wrong, but as a blind guess, I suspect the mobility API to be not built correctly.

I forgot to mention that I use mac os 10.6.8 with qt creator 2.2.1.
These are the only errors that are shown

To be mentioned that when simply trying to display a map in main it works like a charm

@ QGeoMappingManager *mappingManager = 0;
// QGeoRoutingManager *routingManager = 0;
// QGeoSearchManager *searchManager = 0;

    QGeoServiceProvider serviceProvider("nokia");
    mappingManager = serviceProvider.mappingManager();
    QGraphicsGeoMap *map = new QGraphicsGeoMap(mappingManager);
    map->resize(350, 480);
    map->setPos(1, 1);
    map->setZoomLevel(13);

    const QGeoCoordinate *q = new QGeoCoordinate(45.783008, 24.148178);
    map->setCenter(*q);

// QGeoMapCircleObject *circ = new QGeoMapCircleObject(*q, 50000);
// circ->setVisible(true);
// map->addMapObject(circ);

    QGraphicsScene scene;
    scene.addItem(map);

    QGraphicsView view(&scene;);
    view.setInteractive(true);
    view.setVisible(true);
    view.show();

Maybe the compilation output can give you a better understanding of what is going on ..

Looks to me that you need to recompile the mobility API stuff with the correct architecture settings (just another guess, though)

I abandoned the project .... it was very weird .... the error was probably generated by some sort of cyclic dependency. Now, that I have put all those things into 1 header and 1 cpp file and now it works. Actually I took the example which can be found in the Qt Creator.
Thank you for all the help.
