sdk package not working (qt)

[modjo756]

I have build a sdk package for sa62 (build with qt5.6.2, meta-qt5 layer krogoth branch). The sdk build fine. After install the package and configure qt creator for the kit, i have this error when i try to deploy an app :

/usr/bin/ld: cannot find -lQt5Widgets /usr/bin/ld: cannot find -lQt5Gui /usr/bin/ld: cannot find -lQt5SerialPort /usr/bin/ld: cannot find -lQt5Core /usr/bin/ld: cannot find -lGLESv2 collect2: error: ld returned 1 exit status make: *** [terminal] Error 1

if i use the neo kit (qt 5.6.1) that i already have the app compile and i can deploy

if i compare the qt5 details of this 2 conf, i can see a difference with mkspec :
neo : linux-oe-g++

secoA62 : linux-g++

i don't know if is the problem ...

I'll dig into this when the eMMC boot works

After a test with udoo quad, same error --> not working. I don't know if it's an issue with meta qt5 or meta-oe ?! I will try a build with an older meta-qt5 to see ...
edit :
i take a precedent layer of qt5 but same result... i have compare qmake version of neo (qt5.6.1) and quad or seco (qt5.6.2 or 5.7) with qmake -query

QMAKE_SPEC is different , linux-g++ for qt5.7 and linux-oe-g++ for neo --> that is good for me. I think it's a problem with mkspec ....

I obtain this error with qt5.7

It's very bad because now we can't deploy an app in the card ! Perhaps a SDKIMAGE_FEATURES ...

I'll take a look into this at the weekend

Sounds like a linking issue. Did you add the modules to your .pro file?

[modjo756]

Yes, this is not the problem (i use project that works before with the older version qt5.6 or example). I think it's a problem with mkspec (use linux-g++ but we needs linux-oe-g++) ! see this comparison between an older qmake that worked with the new generated.
I have send a mail to yoctoProject and meta-freescale but not answer !
I found that but i'm not sure that is the same problem

[cyrilfr]

Personally I use that layer : https://github.com/meta-qt5/meta-qt5. It has nothing to do with meta-freescale.

[modjo756]

Yes i use also meta-qt5, but on meta-freescale they have otavio salvador who is a maintainer of meta-qt5. If you know a mailing list, forum ... on meta-qt5 let me know please.

@graugans @cyrilfr i have found the problem with sdk. Now to have the deploy working, it's needed to add linux-oe-g++ to Qt mkspec, see the picture under !

[graugans]

Hi, what branch are you using? For krogoth a krogoth branch in meta-qt5 is recommended. It could be possible names of tools changed and so the qt5 tutorial needs an update. If you find some time to create a minimal example we can provide this and refer to it

[modjo756]

Hi graugans, i use master for meta-qt5 and krogoth for the other (but this is the same result with krogoth branch, tested). The only thing that is needed to change is to add linux-oe-g++ to Qt mkspes field. I can create an example but can you preceise your ask ? Would you like a tutorial to configure QtCreator or deployment example ?

[modjo756]

I close this issue, another user have tested it (mailing list meta-freescale) and works too for him.

@graugans , @cyrilfr about this problem i posted on yocto mailing list this issue. Someone post me a private message that explain this :
_Problem lays in the patch 0008-configure-paths-for-target-qmake-properly.patch used in nativesdk-qtbase_git.bb.

From the patch:

+if [ "$QT_CROSS_COMPILE" = "yes" ] ; then
+ shortxspec=linux-g++
+ shortspec=linux-g++
+else
+ shortxspec=`echo $XQMAKESPEC | sed "s,^${relpath}/mkspecs/,,"`
+ shortspec=`echo $QMAKESPEC | sed "s,^${relpath}/mkspecs/,,"`
+fi

Since QT_CROSS_COMPILE then it sets the SPEC to linux-g++.

To test if you have the same problem as me.

Remove the patch from the recipe nativesdk-qtbase_git.bb and rebuild.

In my last build i did this and this resolve the problem (no need to change QT mkspecs in qtcreator). Do you think we push this on the recipe ?
