QtonPi

My Qt framework 5.9 is build ed with the support of Gstreamer1.0 backend. But installing gstreamer-omx is not giving me accelerated media playback .

Hi, You are application does something wrong, the Pi is overloaded by something, etc. Did you try with one of the Qt example ? Do you also have that problem ? Also, what model of Pi are you talking about ? What does your application do ?

I rebuilt Qt, Python, SIP and PyQt5 overnight, using the -device and -device-option flags in the Qt ./configure process and eglfs is working now :) The only issue I've now got is a warning regarding a missing font directory, as apparently Qt no longer ships with fonts. This should be a pretty simple fix however.

I believe I have.. I followed https://wiki.qt.io/Native_Build_of_Qt5_on_a_Raspberry_Pi and downloaded the last version, version 5.9.2. But I did not edit ~/opt/qt5/qtbase/configure script - because there were no QT_CFLAGS_DBUS statments in the downloaded version. I started with a Raspberry Pi 3 flashed with Jessie Light 2017-07-05. Then, after a raspian-setup I continued without rebooting with: sudo apt-get install --no-install-recommends xserver-xorg sudo apt-get install --no-install-recommends xinit sudo apt-get install raspberrypi-ui-mods and the packages needed for compiling according to the article. I had to install git in addition. Every step ran to completion without any errors and I ran the qube test at the end of the article. It worked in console mode, and after a reboot - also under X11. But, I did not get the result I wanted. The cube application took the whole screen. It is not a "good" display environment citizen. I want my app to coexist with other applications. My question is: What can I do for creating an applicaton that run in the display environment? Do I have to run the configure script with other parameters or is there another way of achieving my goal? This is the line I have used: Command line: -v -opengl es2 -device linux-rasp-pi-g+ -device-option CROSS_COMPILE=/usr/bin/ -opensource -confirm-license -optimized-qmake -reduce-exports -release -qt-pcre -make libs -prefix /usr/local/qt5

Thank you, @StoatPatronus , that seemed to do the trick for me too!

Thanks, that works! Use as follows: LIBS += -L$$[QT_SYSROOT]/my/lib/location -lmisc Official documentation here: http://doc.qt.io/qt-5.9/qmake-language.html (See "Accessing qmake Properties".)

So as @yuvaram wrote, you are using a 32bit operating system, it won't be able to run your 64bit application.

I'd recommend using some other prefix for your environment variable. At some point it could be used by the project or some colleague of you might think it's an official environment variable used by the Qt project.

Hi @tekojo , thanks for the anwer! Damn, I was hoping differntely x), but it is super easy, and in my opinion not promoted enough, before that Tweet I had no idea what Qt For Device Creation would support. I knew it existed, but that was as far as it got. There's still the 30 day test trial I could use, and I'll contact the support, maybe theres a single/private device license that can be negotiate...

Thanks @raven-worx I'm not convinced that any proactive action ought to be required, but I have verified that adding qputenv("DISPLAY", ":0"); before creating the QApplication instance does indeed work.

@hardikh i actually followed the wiki page and the blog for cross compiling qt..still i am facing this error..does setting the physical height and width solved the problem? i tried by setting the QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT in .bashrc but no change can you mention what steps you followed for correcting it

I have verified that preserving the same paths (in my case, /opt/Qt) on all hosts for the cross-compiled output, works fine.

@eliar can you be more clear how to do that... pi@raspberrypi:~ $ export LD_LIBRARY_PATH=/usr/local/qt5pi/lib pi@raspberrypi:~ $ export QT_LOGGING_RULES=qt.qpa.*=true pi@raspberrypi:~ $ ./qopenglwidget qt.qpa.egldeviceintegration: EGL device integration plugin keys: ("eglfs_emu", "eglfs_kms_egldevice", "eglfs_kms", "eglfs_x11") qt.qpa.egldeviceintegration: EGL device integration plugin keys (sorted): ("eglfs_brcm", "eglfs_kms", "eglfs_emu", "eglfs_kms_egldevice", "eglfs_x11") qt.qpa.egldeviceintegration: Trying to load device EGL integration "eglfs_brcm" qt.qpa.egldeviceintegration: Failed to load EGL device integration "eglfs_brcm" qt.qpa.egldeviceintegration: Trying to load device EGL integration "eglfs_kms" qt.qpa.eglfs.kms: New DRM/KMS via GBM integration created qt.qpa.egldeviceintegration: Using EGL device integration "eglfs_kms" qt.qpa.eglfs.kms: platformInit: Opening DRM device qt.qpa.input: udev device discovery for type QFlagsQDeviceDiscovery::QDeviceType(Device_DRM|Device_VideoMask) qt.qpa.input: Found matching devices () qt.qpa.eglfs.kms: Found the following video devices: () Could not find DRM device!

@lina Did you see these guidelines already? Bascially any Qt (Qt5.1.0 or later) you may use, but you have to determine the proper Android version for your target platform. That you have to aline with your Android SDK.
