4. Qt 5.5 Linux x86-64 cross compile to arm 32

Qt 5.5 Linux x86-64 cross compile to arm 32


  • Hi All,

    I would like to use a Wandboard for my job. I have a x86-64 bits laptop to development.
    I downloaded the qt 5.5 source and I compiled it with these config settings:
    ./configure -opensource -confirm-license -make libs -device imx6
    -device-option CROSS_COMPILE=arm-linux-gnueabihf-
    -sysroot /home/zamek/embedded/wandboard/rootfs/current
    -prefix /usr/lib/qt -no-gcc-sysroot -no-glib -no-nis -no-libudev -no-iconv
    -no-rpath -no-icu -no-directfb -evdev -no-fontconfig

    it compiled successfully and there was a new qt directory on my rootfs /usr/lib/qt.

    After that I tried to use it with QtCreator, I added a new compiler named arm-linux-gnueabihf which is the same as I used in compiling qt. I could add a new qt version from my rootfs as well.
    When I want to add a new kit named wandboard and I set all the parameters, qtcreator said an error:
    "The compiler arm-linux-gnueabihf (arm-linux-generic-elf-32bit) cannot produce code for Qt version "Qt 5.5.1 in PATH (qt5)" (x86-linux-generic-elf-32bit) <<<<<<<<<!!!!!!!!!!!!!!!!!!!!!!!!!!!

    My qt5 is (compiled with arm-linux-gnueabihf) is:

    Name: Qt 5.5.1 (lib)

    My rootfs is a arm debian stable.

    Where qtcreator founds the x86-linux-generic-elf-32bit in my rootfs?

    thx
