@micland I thought of that but discarded the idea because Raspbian seems to be the de facto standard distribution for RPi, and IMHO the mkspec should work out-of-the-box with the Rasbian library paths. Or at least there should be a mkspec for Raspbian. Also, if I understand it right, the symlinks won't fix the run time error. (But I have to admit I am not at all sure I understand it right.) One thing that puzzles me is the big difference between RPi3 and RPi2 mkspecs. Wouldn't it be enough to change the processor optimization flags?

Install latest mingw... I had problems with make without it...

@tekojo I knew something wasn't right :D

@romsharkov You may use a custom theme to turn off the ActionBar. Example: quickandroid/apptheme.xml at master · benlau/quickandroid quickandroid/AndroidManifest.xml at master · benlau/quickandroid Document: Complete Guide to Making a Splash Screen for your QML Android Application — Medium

Thanks @Mathan-M, It also worked for me. I think we can mark this as solved.

@Roy-a , did you finally find a solution for this problem ?

yes indeed everything goes smoothly when compiling with rootfs provided with ti-sdk. thank you for replay. I will put here instruction howto . Best regards

@benlau and @SGaist tanks for the help, I didn't know there is an openCV just for android. I solved my problem adding the openCV sdk for android at my project with this: TEMPLATE = app QT += qml quick CONFIG += c++11 SOURCES += main.cpp \ processaimagem.cpp \ provedorimagem.cpp INCLUDEPATH += /home/gpca/Qt/OpenCV-android-sdk/sdk/native/jni/include OPENCV3RDPARTYLIBS = /home/gpca/Qt/OpenCV-android-sdk/sdk/native/3rdparty/libs/armeabi-v7a OPENCVNATIVELIBS = /home/gpca/Qt/OpenCV-android-sdk/sdk/native/libs/armeabi-v7a LIBS += $$OPENCV3RDPARTYLIBS/liblibtiff.a $$OPENCV3RDPARTYLIBS/liblibjpeg.a $$OPENCV3RDPARTYLIBS/liblibjasper.a $$OPENCV3RDPARTYLIBS/liblibpng.a $$OPENCV3RDPARTYLIBS/libtbb.a $$OPENCV3RDPARTYLIBS/libIlmImf.a LIBS += $$OPENCVNATIVELIBS/libopencv_core.a $$OPENCVNATIVELIBS/libopencv_androidcamera.a $$OPENCVNATIVELIBS/libopencv_flann.a $$OPENCVNATIVELIBS/libopencv_imgproc.a $$OPENCVNATIVELIBS/libopencv_highgui.a $$OPENCVNATIVELIBS/libopencv_features2d.a $$OPENCVNATIVELIBS/libopencv_calib3d.a $$OPENCVNATIVELIBS/libopencv_ml.a $$OPENCVNATIVELIBS/libopencv_objdetect.a $$OPENCVNATIVELIBS/libopencv_photo.a $$OPENCVNATIVELIBS/libopencv_stitching.a $$OPENCVNATIVELIBS/libopencv_superres.a $$OPENCVNATIVELIBS/libopencv_ts.a $$OPENCVNATIVELIBS/libopencv_video.a $$OPENCVNATIVELIBS/libopencv_videostab.a $$OPENCVNATIVELIBS/libopencv_java.so ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android-sources RESOURCES += qml.qrc # Additional import path used to resolve QML modules in Qt Creator's code model QML_IMPORT_PATH = # Default rules for deployment. include(deployment.pri) DISTFILES += \ android/AndroidManifest.xml \ android/gradle/wrapper/gradle-wrapper.jar \ android/gradlew \ android/res/values/libs.xml \ android/build.gradle \ android/gradle/wrapper/gradle-wrapper.properties \ android/gradlew.bat ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android HEADERS += \ processaimagem.h \ provedorimagem.h Again, thank you both for the help.

I finally found my issue. My include path did not point to the great folder (the one containing the QObject header) To fix it I used the include path flag with the ndk-build command

Hi and welcome to devnet ! Thanks for sharing the report link ! It has been marked as solved for Qt 5.7.1. So please mark this thread as solved using the "Topic Tools" button so other forum users may know a solution has been found :)

Glad you found out and thanks for sharing ! Since you have it working now, please mark the thread as solved using the "Topic Tools" button so that other forum users may know a solution has been found :)

Good :) Thanks for the followup

@micland said: QT_QPA_EGLFS_HIDECURSOR var is not set thanks for support :)

Hi, What driver are you using ? Did you check if there where any need to calibrate anything ?

The important point is that you could solve it :)

Now its working. wrongly used the namespace name in the .qml fle instead of id. QtCPPSearchVOne { id: objQtCPPSearchVOne Button { id: btnSubmit onClicked:{ objQtCPPSearchVOne.funsearchMap() } } }
