Any developer using EyeTribe on Qt framework (C++) ?

Hi,
Is there anyone here using Eye Tribe on Qt framework [ http://www.qt.io ].
Now that Qt supports following platforms, it's a great opportunity to use Eye Tribe in creative ways.

Android
iOS
Windows
Linux/X11
OS X
Windows Runtime
WinCE

If any of you share the same interest, please respond to this thread and we can collaborate.
Thanks.

I am trying to use the Eyetribe SDK with Qt creator at the moment, but I'm having difficulties linking it with boost.
I am using Qt 4.8.4 and Qt Creator 2.4.1 (with MinGW compiler)
I use boost 1.52.

I added :

"gazeapi.h/cpp", "gazeapi_interfaces.h", "gazeapi_types.h", "gazeapi_observable.hpp", "gazeapi_parser.hpp/cpp" and "gazeapi_socket.hpp/cpp" to my project.

I created a 'MyGaze' class and filled it with the C++ exemple.

To build boost :
- I first added "C:/Qt/qtcreator-2.4.1/mingw/bin" to my PATH variable
- then opened a command prompt
- went to "C:/boost_1_52"
- typed "bootstrap.bat mingw"
- and then "b2 toolset=gcc build-type=complete stage" (this took a long time (about 2h))

In my .pro file I have added :

Code: Select all

INCLUDEPATH += C:/boost_1_52
LIBS += -LC:/boost_1_52/stage/lib \
-lboost_system-mgw48-mt-1_52 \
-lboost_thread-mgw48-mt-1-52

#"libboost_system..." needs this library
LIBS += -LC:/windows_sdk/lib \
-lWS2_32

My main.cpp is very simple :

Code: Select all

#include <QtCore/QCoreApplication>
#include "gazeapi.h"
#include "mygaze.h"

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
   
   // MyGaze test;

    return a.exec();
}

When I try to build my project I have a lot of 'undefined reference', there are two types of them :
- some with 'thread' in it like :

Code: Select all

undefined reference to `_imp___ZN5boost6thread4joinEv'
undefined reference to `_imp___ZN5boost6thread12start_threadEv'

-some that looks like :

Code: Select all

undefined reference to `boost::system::generic_category()'
undefined reference to `boost::system::system_category()'

I really do not see how to fix these errors

Problem solved.

I had strawberry perl installed on my computer, and it has mingw in it.

I thought I was building boost with the mingw that comes with qt creator but in fact i was building boost with the mingw that comes with strawberry perl.

I uninstalled strawberry perl, rebuilt boost and linked it to my project.
It works fine now.
