Raspberry side (Client) :

first connect raspberry with ssh then;

sudo nano etcssh/ssh_config sudo nano /etc/ssh/sshd_config

find the line PermitRootLogin and make it comment out. And cange front of to root login with yes.

give new pass

sudo passwd root sudo reboot

uncomment last line which is about the apt-get update

nano etcapt/sources.list
apt-get dist-upgrade reboot rpi-update reboot

qmake install

sudo apt-get build-dep qt5-qmake sudo apt-get build-dep libqt5webengine-data sudo apt-get install libudev-dev libinput-dev libts-dev libxcb-xinerama0-dev libxcb-xinerama0

create directiory of qt5pi

mkdir /usr/local/qt5pi chown -R root:root /usr/local/qt5pi

in Linux side ( Host ) ?

for update

apt-get update

get upgrade from news

apt-get -y upgrade

new packages

apt-get install gcc git bison python gperf pkg-config

create directory on opt this will be in root directory cd ../../ or cd /

sudo mkdir opt/qt5pi sudo chown 1000:1000 opt/qt5pi cd opt/qt5pi git clone https://github.com/raspberrypi/tools

nano ~/.bashrc

add below line in the last part :

export PATH=$PATH:/opt/qt5pi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin

above will give export path

you can use reboot or re run bashrc file I am going to use re run

. ~/.bashrc

from this http://download.qt.io/official_releases/qt/ you need to select your version we are going to use qt5.12 you need qt-everywhere path that zip file for qt file which will we use for cross compile it will support qt required documents for compile

download tar file from given link

wget download.qt.io/official_releases/qt/5.12/5.12.5/single/qt-everywhere-src-5.12.5.tar.xz tar xf qt-everywhere-5.12.5.tar.xz ## if you download another version use your ##downloaded file name it will recompress your tar file

below line copy linux arm file to new directory

cp -R qt-everywhere-src-5.12.5/qtbase/mkspecs/linux-arm-gnueabi-g++ qt-everywhere-src-5.12.5/qtbase/mkspecs/linux-arm-gnueabihf-g++

with sed you can add or edit your text file in this line adding new config line in your qmake.conf file

sed -i -e 's/arm-linux-gnueabi-/arm-linux-gnueabihf-/g' qt-everywhere-src-5.12.5/qtbase/mkspecs/linux-arm-gnueabihf-g++/qmake.conf

create new directory for rsync with your raspberry it will help to get important file from your remote !

rsync -avz root@your_raspberry_pi_ip_address:/lib sysroot

rsync -avz root@your_raspberry_pi_ip_address:/usr/include sysroot/usr

rsync -avz root@your_raspberry_pi_ip_address:/usr/lib sysroot/usr

rsync -avz root@your_raspberry_pi_ip_address:/opt/vc sysroot/opt

move libegl files with mv command

mv sysroot/usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0 sysroot/usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0_backup

when you call libegls.so.1.0.0 automaticall call first line file

ln use for refer to other file

ln -s sysroot/opt/vc/lib/libEGL.so sysroot/usr/lib/arm-linux-gnueabihf/libEGL.so.1.0.0

mv sysroot/usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0 sysroot/usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0_backup

ln -s sysroot/opt/vc/lib/libGLESv2.so sysroot/usr/lib/arm-linux-gnueabihf/libGLESv2.so.2.0.0

ln -s sysroot/opt/vc/lib/libEGL.so sysroot/opt/vc/lib/libEGL.so.1

ln -s sysroot/opt/vc/lib/libGLESv2.so sysroot/opt/vc/lib/libGLESv2.so.2

wget https://raw.githubusercontent.com/riscv/riscv-poky/master/scripts/sysroot-relativelinks.py

get executable mode

chmod +x sysroot-relativelinks.py ./sysroot-relativelinks.py sysroot

check your remote file again

rsync -avz root@your_raspberry_pi_ip_address:/lib sysroot

rsync -avz root@your_raspberry_pi_ip_address:/usr/include sysroot/usr

rsync -avz root@your_raspberry_pi_ip_address:/usr/lib sysroot/usr

rsync -avz root@your_raspberry_pi_ip_address:/opt/vc sysroot/opt

re-run pythonn script

./sysroot-relativelinks.py sysroot

make directory for build and go that one

mkdir qt5build cd qt5build

lets call configure file with your qt-everywhere file name if you ae using any other rasp you need to change to infront of -device to with below comments :

##raspbery pi 0  = linux-rasp-pi-g++
    ## raspberry pi 2 = linux-rasp-pi2-g++
    ## raspberry pi 3 = linux-rasp-pi3-g++
    ## vor pi3 + vc4 direver = linux-rasp-pi3-vc4-g++

../qt-everywhere-src-5.10.1/configure -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- -sysroot /opt/qt5pi/sysroot -prefix /usr/local/qt5pi -opensource -confirm-license -skip qtscript -nomake examples -make libs -pkg-config -no-use-gold-linker -v

for use four core make it with -j4 it will make your qmake file

make -j8

make install

cd /opt/qt5pi

rsync -avz sysroot/usr/local/qt5pi root@10.80.1.217:/usr/local

after this one go your project file where qmake stay and call

/opt/qt5pi/sysroot/usr/local/qt5pi/bin/qmake

you will see make file

make

send your file to raspberry with ssh

scp filename root@your_raspberry_pi_ip_address : ##here directroy if you give like that it will copy to home

run with ./project name in your rasp

Follow Below to add your Cross compile file To QT that means when you press debug, your project will work on the raspberry pi !

if you want to use qt creator as cross compiler when press to run button follow below lines

first go tools/options/ devices

press Add and enter information dont forget username should be root !

then enter kits>debuggers add path : /opt/qt5pi/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb

Add c & c++ compilers

path: /opt/qt5pi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-g++

path: /opt/qt5pi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-gcc
