    thank you SGaist, but how could you know the compiler used to build the distribution?

    However as now I have the cross-compiler I used the cross-compile-tools I downloaded from the wiki to fix symlinks(what are they?) and lib paths(as the wiki says) . So I command:

    cd ~/opt/cross-compile-tools sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc
    
    

    But i don' think there was some changes, because I tried to modify the path, and I inserted a wrong one, but the command didn' t return any error. Moreover it seemed no time spended to execute the command.

      Usually looking at the compiler package provided by the distribution provides that info.

      The script itself is pretty fast.

      Which version of the script did you use exactly ?

        I don' t know. The script is called fixQualifiedLibraryPaths and I have only the code, no infos about the version:

        #!/bin/bash
        #This script is ugly, feel free to fix it
        
        if [ "$#" -ne 1 ]; then
            echo "usage ./cmd target-rootfs"
            exit -1
        fi
        
        #passed args
        ROOTFS=$1
        TOOLCHAIN=arm-linux-gnueabihf
        
        INITIAL_DIR=$PWD
        
        function adjustSymLinks
        {
            echo "Adjusting the symlinks in $1 to be relative"
            cd $1
            find . -maxdepth 1 -type l | while read i;
            do qualifies=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | grep ^/lib)
            if [ -n "$qualifies" ]; then
            newPath=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | sed -e "s,\`,,g" | sed -e "s,',,g" | sed -e "s,^/lib,$2/lib,g");
            echo $i
            echo $newPath;
            sudo rm $i;
            sudo ln -s $newPath $i;
            fi
            done
            cd $INITIAL_DIR
        }
        
        adjustSymLinks $ROOTFS/usr/lib "../.."
        
        echo "Testing for existence of potential debian multi-arch dir: $DEB_MULTI_ARCH_MADNESS"
        
        if [ -n "$DEB_MULTI_ARCH_MADNESS" -a -e "$DEB_MULTI_ARCH_MADNESS" ]; then
            echo "Debian multiarch dir exists, adjusting"
            adjustSymLinks $DEB_MULTI_ARCH_MADNESS "../../.."
        fi
        

        Have you a script you are sure that it will work well? I am trying to cross-compile Qt5

          You should have some feedback. One thing I'd do use the full path rather than ~.

            Hi SGaist,

            yes I tried to use the full path by command:

            ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs /home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc
            

            and what I receiced was this error:

            usage ./cmd target-rootfs
            

            Well at that poiint I tried to run this command without the cross compiler path:

            ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs
            

            And I received this:

            Adjusting the symlinks in /mnt/rasp-pi-rootfs/usr/lib to be relative
            Testing for existence of potential debian multi-arch dir:
            

            But I don' t think it is right as I didn' t use any cross compiler in the command, infact when I after run the command to cross compile, it happened:

            <srcbase> = /home/michele/opt/qt5/qtbase

            Qt is now configured for building. Just run 'make'.
            Once everything is built, you must run 'make install'.
            Qt will be installed into '/mnt/rasp-pi-rootfs/usr/local/qt5pi'.
            
            Prior to reconfiguration, make sure you remove any leftovers from
            the previous build.
            
            

            Then i run make -j4 and I receveid this error:

              Your log is not complete, please restart without the -j parameter so you can have the exact point of failure.

                Hello everyone,

                I am cross-compiling Qt5 following the instruction from the wiki at https://wiki.qt.io/Raspberry_Pi_Beginners_Guide, but I had some troubles.

                I followed all the previous instruction and I had no errors but when i run the command:

                ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi make -j 4 sudo make install
                

                The result was this:

                <srcbase> = /opt/qt5/qtbase 
                <outbase> = /opt/qt5/qtbase 
                Creating qmake...
                .Done.
                ERROR: Invalid command line parameter 'make'.
                

                Is this result correct? I have Ubuntu 16.04. Thank you in advance

                @BadBlood The sample commands are wrong. Either you need to && between the individual commands, or run then individually. For example:

                ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi && make -j 4 && sudo make install
                

                OR

                > ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi
                > make -j 4
                > sudo make install
                

                Also, maybe try to git from github:

                > git clone https://github.com/qt/qtbase.git -b 5.8
                

                Change 2) Compiling qt base:

                > cd ~/opt/cross-compile-tools
                > sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc
                

                Also, take a look at this bug if you're using raspberrypi/tools:
                Update toolchain to support gcc 4.9 raspi3/jessie #73

                  Thank you very much guys,

                  I had some problems with cross-compiling and I couldn' t to reply to SGaist. Thank you for && advice, i didn' t know that, and thank you for the link.

                  I couldn' t reply to SGaist beacuse I wanted to repeat all passages: I had problems with the cross compiling configuration command. In particular when I run the command:

                  ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi
                  

                  I received this error:

                    @SGaist said in Problem cross-compiling Qt5 from Ubuntu to Raspbian(Raspberry pi3):

                    Your log is not complete, please restart without the -j parameter so you can have the exact point of failure.

                    Hi SGaist, sorry for delay

                    The problem was the cross compiler, if I made the configuration with 4.9.3 v. It returned me the error I attached, but if I use the other one(4.7) cross compiling configuration works fine.

                    However when i run "make" I had the error. As the log is too big to attach here, i will send you the one drive link to the log file containng the error I received.

                          You can try the workaround described here.

                            https://1drv.ms/u/s!As3fa8j7GVzZl3som_ciawx9hu50

                            First lines were cutted, but there are the most important about the error.

                              I'd still opt for changing to a more recent version of gcc like 4.9

                                I tried to use gcc 4.9, but it returns the error during cross compiling configuration, I linked few weeks ago. The cross compiler I chose is in the directory:

                                /home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin

                                  I was able to create a raspbian with Qt5 following the guide at this link:

                                  https://medium.com/@amirmann/how-to-cross-compile-qt-for-raspberry-pi-3-on-linux-ubuntu-for-beginners-75acf2a078c

                                  Next I put the image onto SD card, and there was all files.
                                  But i had problems to find raspberry with the laptop through QT5 running on that, I' m going to open an other topic for that. Thank you.

                                    If it hasn't already been noticed the path setting script checks the number of parameters passed and is expecting 1 but 2 are being passed. I changed "$#" -ne 1 to "$#" -ne 2 and it ran without the error message.

                                    The second parameter is used in the script so it is needed.

                                    However I now get an error 'Cannot run compiler '/home/sam/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++'

                                    (It does exist there)

                                      @TV_man said in Problem cross-compiling Qt5 from Ubuntu to Raspbian(Raspberry pi3):

                                      /home/sam/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++

                                      can you run it manually from a terminal?
