    agocs : i tried this and switched the compilation flags to : @-marm -mfpu=neon -mtune=cortex-a7 -march=armv7-a -mabi=aapcs-linux @ The build made it thru. Some qt samples work fine, but i'm encountering issues with the QML webview. For some reason it doesnt load at all. I also checked some samples using it like flickrview and the whole app starts fine but the WebView area is desperately black. the only log i'm getting from commandline is : @QML debugging is enabled. Only use this in a safe environment. Failed to start " "QtWebProcess" 15"@ any clue is welcome :)

    It is usb storage+wifi. ref. "https://qt-project.org/forums/viewthread/52955/":https://qt-project.org/forums/viewthread/52955/ But we will layout one for ours. BTW, I will try the WiFi. QTcpSocket or Bearer Manager API etc?.....I am pretty much a newbie to Qt. Does Qt REALLY support WiFi for ios and android ??? My Storage is WiFi direct. Someone say Qt not support. http://stackoverflow.com/questions/24096295/does-qt-support-wi-fi-direct-p2p-connections-on-mobile-platforms my storage's document: http://icirround.com/en/ishowdrive/

    It's basically the same thing, but as a person which is developing an app for mobile using Qt/C++ I strongly recommend learning to combine QML with C++; QML for GUI and C++ for the rest. When it comes to GUI mobile development Qt/QML is far ahead than Qt/C++ from my point of view, with Qt/C++ for GUI you will have to do some frustrating workarounds. I myself am looking into Qt Quick so I can rebuild my app's GUI using QML and extending it with C++.

    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...
