Mobile and Embedded

Hello, qt_for_embedded, or anyone that knows ... did you manage to solve the problem when trying to compile qt for arm in windows? I am having the same problem and not sure how to proceed at this moment. What is this "test" command? This is what I get: @PS C:\Qt\qt-everywhere-opensource-src-5.3.1> jom jom 1.0.14 - empower your cores 'test' is not recognized as an internal or external command, operable program or batch file. A subdirectory or file qtbase already exists. Error occurred while processing: qtbase. A subdirectory or file qtbase\ already exists. Error occurred while processing: qtbase. jom: C:\Qt\qt-everywhere-opensource-src-5.3.1\Makefile [module-qtbase-make_first] Error 1@ I am using the "linaro toolchain for windows":http://releases.linaro.org/13.06/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.8-2013.06-20130620_win32.exe (I'm using Win7) and I've configured Qt to compile with the following options. @.\configure -prefix C:\Qt\qt-everywhere-opensource-src-5.3.1\qtbase -release -opensource -confirm-license -embedded -neon -platform win32-g++ -xplatform linux-arm-gnueabihf-g++ -skip qtwebkit -skip qtwebkit-examples -skip qtserialport -skip qttools -skip qtx11extras -skip qtandroidextras -nomake tools -nomake examples -nomake tests -no-opengl -no-compile-examples -no-widgets -no-gui -no-opengl -no-angle@ The configuration step works well. Any help is appreciated. Thanks!

Last time i compiled with qt-creator, i was implementing some gui-stuff (dialog's). Nothing strange. I just decided to use the "shadow" and change the folder-structure of my project. But i dont think that changes anything. Now i am getting this even with a new qt-project "hello world"...

There are the patch to enable support for Android: https://codereview.qt-project.org/#/c/84338/ In this patch are used a wrapper of the JAVA's classes from this project: https://github.com/mik3y/usb-serial-for-android In this case is used the direct USB-host mode, so the root rights are not need. PS: But I do not test it, so I can't promise that this will work.

libqte.a is a static lib, dll or so, dylib are shared

There's no button, you have to edit your original post and modify the title by hand

The graphicsview is already a part of the main window and is enabled. So calling show() is not required. Also, it's not Qt that's giving the error i believe, but, the video sink element in the gstreamer pipeline. "When you send winId to gstreamer it will paint the frames on a whole window. And since graphicsview is a central widget all buttons belong to the same window. So gstreamer over-paint them." I thought so, that's why i did setCentralWidget(ui->graphicsView) to only display it in garphicsview part of the mainwindow. The mainwindow has the central widget and everything is in the central widget. With setCentralWidget(ui->graphicsView) the video is displayed only in the graphicsview window, but, still the buttons do not show once the video playback starts.

Good. I'll adopt this post then, to get it off the unanswered list ;).

No, I afraid its similar to this "issue":http://stackoverflow.com/questions/7651374/arm-linux-androideabi-g-exe-createprocess-no-such-file-or-directory-error But Even a shorter path didn't help me. :(

Hi, You don't need WebKit for QML and Qt Quick. You need WebKit for HTML 5. Note: Qt 5.4 has not been released yet. It is scheduled to be released at the end of October (see "here":http://qt-project.org/wiki/Qt-5.4-release). For now, I recommend you use Qt 5.3.1 for your project.

Hi, IIRC, you can access the various GPIO from the board through the sys file system. You could do the equivalent read and write to that FS in Qt Hope it helps

From what I know the directories in the home dir should never used to store persistent data because they are always overwritten not only by Qt, but also when you will put an update via Google Play. So, use another location !!

tks for your post.But what's the real reason? [quote author="wind" date="1389575684"]Hi! I had the same problem and I fixed it by making these changes in the QML file: @import QtSensors 5.0 as Sensors ... Sensors.Accelerometer { .... } @ Here is a link of reference: "https://qt-project.org/doc/qt-5/qtsensors-qmlmodule.html":https://qt-project.org/doc/qt-5/qtsensors-qmlmodule.html[/quote]

Thank you for that. That makes a lot more sense now.

Yes, you need the Windows 8 Professional... as the Microsoft guide indicate as requirements: http://msdn.microsoft.com/en-us/library/windows/apps/ff626524(v=vs.105).aspx

I downloaded ARM cross compiler, QtCreator and qmake for development and buildroot for deployment. I have problem in qmake configuration, ARM compiler is tested working. Can guide me step by step.bq.

Can Anyone here confirm me abt QtSerialPort working with ti linaro toolchain in below mentioned link please. http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/latest/index_FDS.html

Hi, AFAIK, using images would give a better performance over gradients as images can be cached if using Image element. Have a look at "this":http://qt-project.org/doc/qt-5/qml-qtquick-gradient.html#performance-and-limitations doc.
