  • hello i have followed this tutorial to install qt5.8
    https://wiki.qt.io/RaspberryPi2EGLFS
    build full qt5.8 no problem
    i have problem when i start qopenglwidget example.

    i have add the link to my qt library in /etc/ld.so.conf.d/qt5pi.conf
    (for my /usr/local/qt5_8pi) and sudo ldconfig

    i have pi@raspberrypi:/usr/lib/arm-linux-gnueabihf $ sudo ldconfig

    can you help me please?

    i blocked since lot of weeks.

    thanks



  • @kickoune103 if you run "file" on the libraries, what does it say that they are ?


  • Moderators

    @kickoune103 Are you sure you built Qt for Rasperry Pi (for ARM) instead for your PC X86_64?
    You can check that calling

    file /usr/local/qt5_8pi/lib/libQt53DLogic.so.5
    

    on your Raspberry Pi.



  • example:
    pi@raspberrypi:~ $ sudo file /usr/local/qt5_8pi/lib/libQt53DLogic.so.5
    /usr/local/qt5_8pi/lib/libQt53DLogic.so.5: data



  • yes 64bits...

    -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- \



  • Something must have gone wrong in your build. Did you build on-device ?



  • no cross compiling like this :
    https://wiki.qt.io/RaspberryPi2EGLFS



  • @kickoune103 thibaud@thibaud-VirtualBox:~$ ./configure -release -opengl es2 -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=/home/thibaud/Bureau/rpi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot /home/thibaud/Bureau/rpi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5_8pi -extprefix /home/thibaud/Bureau/rpi/qt5_8pi -hostprefix /home/thibaud/Bureau/rpi/qt5_8 -v



  • Ok, I do all my builds on-device.
    But, check that the library files produced on your build machine are ARM binaries, use file for example, should respond with something like:

    ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV) .

    and if not, then your build environment is broken.

    And check that they don't break when do transfer them over to your Pi.



  • in my pi:
    root@raspberrypi:/usr/local/qt5_8pi/lib# file libQt5Gui.so.5.8.0
    libQt5Gui.so.5.8.0: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, BuildID[sha1]=4bcd5c6b508a7f287465b546df892a89b8cb6867, stripped



  • host:
    thibaud@thibaud-VirtualBox:~/Bureau/rpi/qt5_8pi/lib$ file libQt53DLogic.so.5
    libQt53DLogic.so.5: symbolic link to libQt53DLogic.so.5.8.0

  • i have copied in USB disk FAT32, symbolink link was disapeard! no error in linux!

    my virtual machine not work in ssh at my work, but work fine at home...
    so i copy in usb at work.



  • export LD_LIBRARY_PATH=/usr/local/qt5_8pi
    example opengl running but no font in qt5_8pi/lib/font ..... is empty !!!!


  • Moderators

    @kickoune103 FAT32 never heard anything about symbolic links - you should use a Linux file system, not FAT32.



  • lib font is empty

    i have install
    libfontconfig1-dev
    libfreetype6-dev

    problem!!!!!

  • Moderators

    @kickoune103 Please call configure with additional -v parameter. Then you will see what exactly is missing.



  • -v it's use before.
    V5_8 works with my pi2 in cross compil.

    $LD_LIBRARY_PATH="/usr/local/qt5_8pi/lib" (for me)
    $QT_QPA_FONTDIR = "/usr/share/fonts/truetype/dejavu"

    for works with this tutorial:
    https://wiki.qt.io/RaspberryPi2EGLFS

    it's work less fontconfig with my previous image.


  • Moderators

    @kickoune103 said in error after start example qt5.8 for raspberrypi:

    -v it's use before.

    Then please post the actual configure output (at least the part where fontconfig is being tested).
