Error messages from configuring Qt 5.7 sources



  • Hi all, I've been trying to configure Qt 5.7 properly for my development work but it seems that errors still persist. I've performed the following actions in configuring and building Qt 5.7 sources:

    1. Unzipped Qt 5.7 sources
    2. Configure qmake.conf for my embedded device
    3. Created a script.sh to execute ./configure with the following parameters:
    ./configure -commercial -confirm-license -release -static -eglfs -linuxfb -opengl es2 -no-qml-debug -no-directfb -no-kms -no-xcb -no-alsa -platform linux-g++-64 -device linux-arm-hi3536-g++ -pkg-config -qt-pcre -qt-zlib -qt-libjpeg -qt-libpng -no-icu -no-nis -no-pch -prefix /home/aa/Hi3536_SDK_V2.0.4.0/v2_qt5.7_arm -device-option CROSS_COMPILE=/opt/hisi-linux/x86-arm/arm-hisiv400-linux/bin/arm-hisiv400-linux-gnueabi- -skip doc -v -qreal float -fontconfig
    
    1. Ran script.sh and basically Qt 5.7 starts building up. It was able to build up with the parameters but there're some errors that persists:
      Here's a copy of the error format:
    checking for XLib... 
    /opt/hisi-linux/x86-arm/arm-hisiv400-linux/bin/arm-hisiv400-linux-gnueabi-g++ -c -pipe -pipe -mcpu=cortex-a7 -mfloat-abi=soft -mfpu=neon-vfpv4 -marm -mthumb-interwork -mfloat-abi=softfp -O2 -Wall -W -fPIC -DEGL_FBDEV -I. -isystem /opt/hisi-linux/x86-arm/arm-hisiv400-linux/target/usr/include -I../../../mkspecs/devices/linux-arm-hi3536-g++ -o xlib.o xlib.cpp
    xlib.cpp:40:22: fatal error: X11/Xlib.h: No such file or directory

    compilation terminated.
    Makefile:204: recipe for target 'xlib.o' failed
    make: *** [xlib.o] Error 1
    XLib disabled.
    

    Basically, based on more or less the same error format as above, I've the following "No such file or directory" for the following headers:

    sqlcli.h
    ibase.h
    mysql.h
    oci.h
    libpg-fe.h
    SQLite.h
    sybfront.h

    proxy.h
    glib.h
    pulse/pulseaudio.h
    libudev.h
    tslib.h
    xcbcommon/xcbcommon.h
    x11/xlib.h
    xcb/xcb.h
    bcm_host.h
    xf86drm.h
    EGL/fbdev_window.h
    egl/egl.H
    egl/eglvivante.h
    double-conversion/double-conversion.h
    ft2build.h
    harfbuzz/hb.h

    1. How may I rectify those errors above?

    @embdev

    You are doing a cross-compilation for another target platform.
    Obviously the required headers are missing. AFAIK you need to ensure corss-compiled libs for your target platform. Those are typically separated from your local setup, because they might not fit with your desktop installation.

    You need to check with the tool chain you are using for cross-compilation.



  • @koahnig do you mean I need to chk with the vendor supplied toolchain for Qt configuration itself?

    If we were to resolve it manually, e.g. able to locate the header, how should we configure the parameter to find the missing header file?


  • Moderators

    @embdev No, you need to check with your vendor whether he can provide you all needed headers/libs for your target.



  • @jsulm I see. let me check if i'm able to get any inputs from them. Thanks!



  • The above mentioned Error messages are from config.tests, you may ignore them via removing -v in your configure parameters.

    Do you see last few lines after configure summary that mentions 'run make' to build qt. If so, just make it :)
