problem about update Qt version to 5.6 with yocto

[chenyw]

I want cross compile qt5.6 for imx6sx,but the lastest Qt version of yocto(i use imx-4.1.15-1.0.0_ga) is 5.5.1,

so i replace source/meta-qt5 with new meta-qt5 directory git clone from https://github.com/meta-qt5/meta-qt5.git and the branch is krogoth,then,bitbake fsl-image-qt5 without any problem except these warnings:

but when i burn u-boot,zImage and rootfs to imx6 and run the qt demo(qt5everywheredemo-1.0), Segmentation fault is display like this:

file:///usr/share/qt5everywheredemo-1.0/qml/QtDemo/main.qml:124:5: QML FontLoader: Cannot load font: "file:///usr/share/qt5everywheredemo-1.0/qml/QtDemo/fonts/PatrickHandSC-Regular.ttf"
Segmentation fault.

so i make a test,  test.qml    like this:

Rectangle{

     color:"green";

}

it can run well; but when i add a line to Rectangle like this

Rectangle{

     color:"green"

     Text{text:"this is a test"}

}

I got a Segmentation fault again.

please tell me what should i do , thank you.

I have tried append freetype fontconfig uic these things to RDEPENDS and DEPENDS in source/meta-qt5/recipes-qt/qt5/qtbase_git.bb,but nothing changed.

Hi Chen,

Apparently you need configure qtbase and build with eglfs in order to work with Qt5.6, also check DEGL_API_FB=1 to prevent imx-gpu-viv from including Xlib from EG/vivante.h

Hope this helps

Hi Bio_TICFSL

Can you describe details about what should i do, how to configure qtbase and eglfs with yocto . Whether the approach that replace meta-qt5 layer with new meta-qt5 directory git clone from https://github.com/meta-qt5/meta-qt5.gitis feasible
