BeagleBone Black, devices generic linux devices impossible to add?

Olfox

Hi all,

I installed full toolchain for BeagleBone Black (BBB).

I'm able to build, send on BBB and run on BBB a qt gui software written in the console ( without the use of qt creator).

I want to do the same by using Qt creator now.

I would like to add a Generic linux device kit to automatically deploy on bbb and see in my Mint developpement PC the result off the execution.

Normally you can add a kit by my button Add in Device section is diable and i can't do it. There s only Local PC option.

Do I use the good version of QT ( QT Creator 3.0.1 based on qt 5.2.1) ?

How to enable the button to add it ?

Thanks alot, i'm little bit stucked now and i really need to continue my project with this nice qt tool.

Thanks a lot.

I succes to add the linux device by instaling the package in my linux mint :

Name of the package : qt creator-plugin-remotelinux

I success to set up the deploy, but now, at execution, i have an error:

connot connect to Xserver.

i would like to add the -X option when qt creator do the ssh connexion but i don't know where...
i try to execute directly with ssh -X terminal connexion and there is a strange error like :

./testqt1: undefined symbol: _ZN7QWidget8qwsEventEP8QWSEvent

If you have any idea , i' really interessted.

Thank you

Hi and welcome to devnet,

Looks like you cross-compiled your application with a Qt 4 for Embedded Linux but you have a classic Qt 4 for X11 on your device. Is that so ?

As for the -X option, I'm not aware of the possibility to add options when Qt Creator does the connection.

Hi SGaist,

Thanks a lot for your fast reply and your welcome.

Do you know how can i check the version on both side to compare and be sure that all is ok ? ( May be command line ? )

Concerning my setting, I followed the Method of Derek Molloy perfectly until the end :

From the looks of the guide, you have a Qt 4 for Embedded Linux so a version that runs without X. AFAIK, the one you have installed on your BBB is a classic X built Qt.

One thing you can do is to uninstall the Qt 4 you have on your BBB and copy the cross-compiled Qt 4 install directory at the exact same place on your BBB (you can always remove the unneeded stuff like header files later)

Ha ok.

Cause the first time, i worked without cross compile.

I installed directly qt creator on the BBB and developed directly on it.

It was a little bit painful so i decided to cross compile. That mean on my beaglebone there is already a qt creator.

Just a question:

If i cross compile for BBB, does the BBB need something special to run a qt program like a JRE for Java?
What i don't understand is that making a main.cpp in my Mint console that shows a GUI window, build it and send via sftp to BBB and execute on BBB works fine, the window appear.

But when i use Qtcreator, i have the error.

i have done another test, create a console project on qt creator and deploy it on BBB, it works.

Only GUI WITH Qt creator doesn't work :(, the most interested part lol.

SGaist

It will need the Qt libraries installed
Are you sure you are using the same version of Qt for both ?
QCoreApplication doesn't depend on any GUI stuff so there's nothing there to prevent it from running.

Olfox

yes for sur, there is a mistake somewhere.

To be clean, i restart form scratch with a new virtual machine and by using qt 5 instead of qt4.

So sorry to not go until the end of this probleme, I'm focus on cross compil for qt 5 now.

Thanks every body for your help and see you for futur problem on qt5 :D
