[SOLVED]Raspberry: QT5 simple MainWindow example : Segmentation Fault.

  • Hi,
    I have compiled qt5 for raspberry by using bakeqtpi.bash and add Raspberry Kit in QtCreator (cross compilation).
    Everything looks ok.
    "Hello world!" example compiled and works fine on Raspberry.
    Simple QT5 MainWindow project compiled fine, but running on the board causes immediate Segmentation Fault.

    gdb tells nothing
    @pi@raspberrypi ~/ $ gdb ./rpi-untitled
    (gdb) run
    Starting program: /home/pi/rpi-untitled

    Program received signal SIGSEGV, Segmentation fault.
    0xb6fe2b50 in ?? () from /lib/ld-linux-armhf.so.3
    (gdb) bt
    #0 0xb6fe2b50 in ?? () from /lib/ld-linux-armhf.so.3

    ldd looks ok

    Can anyone help?

  • Originally I copied Qt library so-files to Raspberry Pi folder, added this folder into ld.so.conf.d and run ldconfig.
    Looks correct, but leads to Segmentation Fault.

    Then i tried "make install" in Host machine qt5 folder and rewrite rasp-pi-rootfs image. This way my application runs perfectly.
