    I modified the serialReceived() function to print the no of bytes received as follows: @void MainWindow::serialReceived() { qDebug() << serial->bytesAvailable(); int ExpectedNoOfBytes = 3; if (ExpectedNoOfBytes == serial->bytesAvailable()){ QByteArray bytearray = serial->readAll(); QString input = QString(bytearray); Write(input); qDebug() << bytearray; } }@ The output is follows: @512 1024 1536 2048 2560 3072 3584 3856 3857 3859 3860 3861 ..... @ Initially it is in multiples of 512 and then it becomes one byte each. Looks like the if statement is not getting executed at all. Can someone tell what is happening here?

    I have successfully compiled WinRT ARM (5.4.1 from git). There was one minor compilation bug (which I reported with a fix). But there is a huge problem with displaying Qml content at the moment (I already submitted a bug report for this as well) where the content is distorted. This is very likely caused by some bug in the Angle/OpenGL wrapper.

    Look at how to include Facebook SDK into Android Qt application: https://github.com/GMaxera/QtFacebook#prepare-facebook-sdk-for-android I think that you should do the same for your lib.

    I have not found a solution for this, but I have found a work-around. I can complete the build if I completely delete the qtwayland directory from the qt-everywhere-src-5.4.0 directory. I am still interested in a real solution that I do not need to delete plugin directories to complete a build. So not marking this as solved and hoping to get some feedback.

    Sam got the point! QWebEnginePage is from Qt 5. My rough guess is you are building the application in Qt 4.xx

    bq. HTML Qt documentation is in the doc/html directory of your Qt installation I downloaded Qt 5.4, it doesn't have doc/html folder. However, Qt documentation in portable offline format (PDF, fb2) is useful to read it with e-book device that doesn't have web browser, but better for eyes health...

    Hi admd91, The key is to set the environment variables correctly. @ source /opt/poky/1.4.1/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi @ When run this script, it loads all the environment variables correctly. Then the environment is set correctly to cross compile your application. After you execute the script, you might run the following @ qmake -project qmake make @ This is one way to build the Qt application. Or else, You can also set the Build and Run options in Qt creator with the cross compiler path and build it directly from the Qt Creator. --Kumara
