Raspbian: /opt/qt/bin/qmake: cannot execute binary file: Exec format error



  • Hi, I'm facing some troubles cross compiling Qt for Raspbian Lite. I has configure my enviroment following these guide https://wiki.qt.io/RaspberryPi2EGLFS and use the following instruction to compile:

    mkdir build
    cd build
    ../configure -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE= /opt/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot /mnt/pi3 -prefix /opt/qt -release -static -opensource -confirm-license -make libs -qt-zlib -qt-libjpeg -qt-libpng -qt-xcb -qt-freetype -qt-pcre -qt-harfbuzz -nomake examples -nomake tests -no-use-gold-linker -skip script
    make -j4
    sudo make install
    
    

    Everything look good. After that I create an image of my sysroot with dd and put it into an SD. When I try to run qmake it promt me this error:

    /opt/qt/bin/qmake: cannot execute binary file: Exec format error
    

    I don't understand why it gets compile for another architecture

    Hi,

    Because qmake and its friends (moc, uic, rcc, etc.) are host tools so they get compiled for the host you are cross-compiling on.
