Boot2Qt: File was compiled ahead of time with an incompatible version of Qt and the original file cannot be found

kkettinger

Hello,

i'm currently deploying with Boot2Qt to an Toradex iMX6 Module with Qt Demos installed (5.14.1). My developing version of Qt is 5.14.2.

When deploying in Debug-Mode, everything runs fine. Deploying in Release-Mode, i get this error on launch:

"FB_MULTI_BUFFER" "2"
"QML2_IMPORT_PATH" "/data/user/qt/qmlplugins"
"QTWEBENGINE_DISABLE_SANDBOX" "1"
"QT_GSTREAMER_CAMERABIN_VIDEOSRC" "mxc_v4l2=imxv4l2videosrc,v4l2src"
"QT_IM_MODULE" "qtvirtualkeyboard"
"QT_QPA_EGLFS_FORCEVSYNC" "1"
"QT_QUICK_CONTROLS_1_STYLE" "Flat"
"XDG_RUNTIME_DIR" "/run/user/0"

QQmlApplicationEngine failed to load component
Thread is stopped
qrc:/main.qml: File was compiled ahead of time with an incompatible version of Qt and the original file cannot be found. Please recompile
quit
Process exited with exit code 255

Does this happen because of different qt versions? I tried to get Qt 5.14.1, but only 5.14.2 or 5.13.x is available.

I appreciate any help, thanks.

Best regards,
Kevin

Thanks SGaist, i fixed it myself. I build a new boot2qt yocto image for my board using this guide: https://doc.qt.io/QtForDeviceCreation/qtee-custom-embedded-linux-image.html
Now there is the correct qt version and the issue went away.

Hi,

Boot2Qt being a commercial product, you should contact the Qt Company directly.
