      @hskoglund said in How to analyze a KIT environment variable: Hi, in a .cpp file you can use getenv(), like this: QString target = getenv("TARGET"); Or qEnvironmentVariable which returns a QString.

      @sierdzio thanks for the example, I think the resolution type is a bit misleading with regard to the reason the bug was closed.

      @iman4k I don't know, I'm not a cross compile expert by any means. I'm just telling you want I can see from the configure you posted. Anyway, should be easy enough to add according to this https://doc.qt.io/qt-5/qtvirtualkeyboard-build.html you can simply open the qtvirtualkeyboard source project with QtCreator and compile it, using your cross compile kit

      @jsulm Yep, absolutely, there is much to read/fiddle with, and may not be portable. May or may not work for OP's particular case. Anyway, whether this or your core dump suggestion (OP should look up how his target Linux OS handles core dumps allowed or not), he has a few approaches to consider now....

      AFAIK, the BPI is very close to the Raspberry Pi, you should take a look at this wiki entry. By the way, why are you trying to build an outdated version of Qt ? The current LTS is the 5.9 series with 5.12 around the corner.

      @SGaist Thanks for the reply. Indeed you are wright. It is very easy actually. I just compiled qt4.8.6 for my system. Then I found the sqlite project in sqldrivers. Compiled this library for my system, copied it and it works! Very easy. Learned again a lot! Thank you all for the great support!

      @Pablo-J.-Rogina Thanks for the time to make example code. It didn't work straight away, this because I use qt4.8 and you the newer one probably. So I changed your code to the older syntax to get it working. I would like to thank you and all others for there help! Again I learned a lot! Thanks for helping!

      @TMJJ001 I would not run this software on your PC - how would it communicate over canbus? Instead you can provide the possibility to connect to this software (server) over network and then write client software for your PC which connects to your server software on the embedded device.

      The solution to that problem is to insert the following call to the constructor of the file processing class: QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8")); Concerning the shell: I use BusyBox (its light) which doesn't provide locale and the environment variables like LANG=en_US.UTF-8. For compiling BusyBox configurations can or have to be given containing CONFIG_LAST_SUPPORTED_WCHAR=0 the number is the last displayable number of the Unicode list, 0 signifies that all characters shall be displayed, it was set to 767 which includes west European characters. The excluded characters are replaced by the character defined in the same configs, in my case it is "?".

      Solved: Now I use wayland-egl and everything is fine. The Long Story to Get the Simple Solution: At first, I used raspberrypi-userland for OpenGL ES. However, it didn't work. I tried VC4 DRM driver in the next. I have struggled to get it work, and I opened an issue on the repository. Then anholt, the author of the driver, updated the Wiki. By following the Wiki, I finally succeeded in getting it work. mesa3d is necessary to provide OpenGL ES API, so I installed it with drm backend. However, it didn't work since eglCreatePbufferSurface is stubbed in the backend. So I had to use other QPA. Next, I tried X11 since Buildroot supports xcb backend, but neither did it work. I thought porting Wayland should be much easier than fixing the issue, and actually it is.

      I am having this exact problem. I compiled my project for an embedded arm device, linux desktop, and windows desktop. The windows and linux hosts display the characters correctly, where the embedded device just shows nothing. I'm using the Noto fonts https://www.google.com/get/noto/#sans-hans and am positive it is being used on the linux desktop, since if I don't copy the font into the same directory as the application, it just shows blocks. When the font is in the directory, it shows everything properly. I tried the same thing with the embedded build, and nothing shows up. The font being loaded, since if it's not in the directory, it complains that it can't load it. Is there some extra switch or rendering tool/application that embedded linux needs? I've tried with both 'linuxfb' and 'egl' platforms with no success. Thanks in advance for any help.

      Ok I see now, that when I configure with toolchain for armbcm from raspbian, it fails, but not because of the compiler ( make goes much further). I will search for another toolchain. I'm curious if the application made by such configured and built qtbase (with previously mentioned armbcm toolchain) will work on Banana. Now only I have to eliminate the problem with qt ide remote connection (error "Server sent invalid f"). If anybody knew how, it would be a blessing for me.

      Hi May I ask how you got this to build? I am trying to compile Qt with the following configuration (for Raspberry Pi): ./configure --prefix=/usr -release -opensource -confirm-license -c++11 -no-largefile -no-qml-debug -system-zlib \ -no-journald -system-libpng -system-freetype -system-libjpeg -system-sqlite -openssl -no-pulseaudio -alsa \ -no-sql-db2 -no-sql-ibase -no-sql-mysql -no-sql-oci -no-sql-odbc -no-sql-psql -no-sql-sqlite2 -no-sql-tds -nomake examples -reduce-exports \ -no-directfb -no-linuxfb -eglfs -no-xcb -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/usr/bin/ -sysroot / Here is my patch: diff --git a/qtwebengine/tools/qmake/mkspecs/features/functions.prf b/qtwebengine/tools/qmake/mkspecs/features/functions.prf index ef0320d..5abaecc 100644 --- a/qtwebengine/tools/qmake/mkspecs/features/functions.prf +++ b/qtwebengine/tools/qmake/mkspecs/features/functions.prf @@ -12,13 +12,9 @@ defineTest(isPlatformSupported) { return(false) } - linux-g++*:!isGCCVersionSupported(): return(false) - !isPythonVersionSupported(): return(false) - linux-g++*|win32-msvc2013|macx-clang: return(true) boot2qt: return(true) - skipBuild("Qt WebEngine can currently only be built for Linux (GCC), Windows (MSVC 2013), OS X (XCode 5.1+) or Qt for Device Creation.") - return(false) + return(true) } defineTest(isPythonVersionSupported) { -- 2.1.0 And it succeeds, but I don't get a message about WebEngine being an unsupported platform.
