Qt installation problem for embedded Linux



  • Hello,
    I am trying to install Qt for my embedded linux board (AcquaA5), but i have the following problem :
    Some warning and some errors appears when i am doing the ./configure command.

    A warning :
    You have not explicitly asked to use pkg-config and are cross-compiling.
    pkg-config will not be used to automatically query cflag/lib parameters for
    dependencies

    floatmath auto-detection... ()
    arm-linux-gnueabihf-g++ -c -pipe -O2 -Wall -W -I../../../mkspecs/linux-arm-gnueabihf-g++ -I. -I/usr/local/arm/include -I/usr/local/arm/ssl/include -o floatmath.o floatmath.cpp
    floatmath.cpp:44:14: warning: unused parameter ‘argc’ [-Wunused-parameter]
    int main(int argc, char **argv)

    An error :
    arm-linux-gnueabihf-g++ -c -pipe -mmmx -O2 -Wall -W -I../../../mkspecs/linux-arm-gnueabihf-g++ -I. -I/usr/local/arm/include -I/usr/local/arm/ssl/include -o mmx.o mmx.cpp
    arm-linux-gnueabihf-g++: error: unrecognized command line option ‘-mmmx’
    Makefile:187 : la recette pour la cible « mmx.o » a échouée
    make: *** [mmx.o] Erreur 1
    mmx disabled.

    I tried to launch the make command but after few minutes, it says me that an error occured.

    Can somebody solve my problem ?
    Thanks.Thank you for your fast answer, it helps me. But i always have the warnings and the fatal errors..

    If you have another error while executing make then you should post it here, else it is not possible to help you.
