I developped a graphical application on Qt and all compiled quite well on linux and windows.

Now I am trying to port it to maemo by using the madde tool. And I am receiving a "bad instruction error".

Please, could someone help to know what is the next step to be done.

Here is the output of whay I am doing.

Thanks!!!

I use the PR1.1 SDK, maybe you do too.
the state machine isnt present in QT4.5.

> ls /usr/include/qt4/QtCore/QState*
ls: /usr/include/qt4/QtCore/QState*: No such file or directory

> ls /opt/qt4-maemo5/include/QtCore/QState*
/opt/qt4-maemo5/include/QtCore/QState /opt/qt4-maemo5/include/QtCore/QStateMachine


PR1.2(SDK) should have this for you by default ( /usr/include/qt4 )
but remember this wont work on your device just yet if you use QT4.6

Alternatively you could compile in PR1.1 SDK using QT4.6 by using qmake from /opt/qt4-maemo5/bin
and it will work on the device for now.

Your include paths point to "../../../../qt/qtsdk-2009.05" which does not look like that is the MADDE qt version?

Make sure you're using the right Qt version and you have the makefiles created by executing "mad qmake".

Thanks!!!

I tried to do so, but I do not find that "/opt/qt4-maemo5/bin" directory.

I tried to install it with apt-get but I did not succed.

How can I install it?

Should I do it on SDK or inside the scratchbox?

i have a similar Problem..
any help for a beginner in QT?

Thank you :-)

Hi,

have you compiled it first for your desktop? Have you cleaned the project before you built it for Maemo?

Daniel

Hey,

I tested the app on desktop and on the QT-simulator.
Both worked fine.

Cleaning up?
Sorry that I have to ask, but what does a cleanup do?
And how do i perform it?

Thanks..
Markus

Cleanup means that remove old objects and generated Makefile.
Makefile is for you desktop environment, not Maemo. You need to
generate new Makefile for Maemo.

$ make distclean
$ mad qmake
$ mad make

okay..
understood that..

But.. I thought QT-Creator generates the makefiles itself for each platform..
Doesn't it?

I installed it like described here and tried out each target.
Everything worked fine except the test on the N900 itself (with error code u can see above)

Markus

Sorry, I don't know about QT-Creator.

This is x86 asm not arm, so you must have leftovers from desktop build.
