Cross compile fails with 'could not read symbols: File in wrong format'

  • Hi,
    I've seen this asked and answered, but the answer doesn't work for me.
    I'm building on Ubuntu 12.04.5 LTS (GNU/Linux 3.2.0-67-generic-pae i686).
    My target is armv7 Cortex-A9.
    I'm using:
    ./configure -embedded arm -xplatform qws/linux-arm-g++
    -arch arm
    -prefix /usr/local/arm
    -platform linux-g++
    -no-qt3support -opensource -confirm-license

    my qmake.conf from qws/linux-arm-g++:

    qmake configuration for building with arm-linux-gnueabihf-g++


    modifications to g++.conf

    make fails with the 'could not read symbols: File in wrong format'.
    I did build first plain vanilla to ensure everything worked.
    Nothing I"ve found works....

    Thank you,

  • The problem was the gcc/g++ in /usr/bin were both arm target.
    So LD did not understand.
