#### Build Qt5.12.10 for RPI3 X11 and EGLFS
1. Get the source code from:
https://download.qt.io/official_releases/qt/5.12/5.12.10/
2. Uncomment developement source (deb-src) in
```
sudo nano /etc/apt/sources.list
```
3. Install these packages on the rpi
```
sudo apt-get build-dep qt4-x11
sudo apt-get build-dep libqt5gui5
sudo apt-get install libudev-dev libinput-dev libts-dev libxcb-xinerama0-dev libxcb-xinerama0\
sudo apt-get build-dep qt5-default
sudo apt-get install libiconv-hook-dev libinput-dev libts-dev bluez libbluetooth-dev libgstreamer1.0-dev libegl1-mesa
sudo apt-get install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev libatspi2.0-dev libdbus-1-dev
```
4. [on RPi] For bluetooth support install
```
Apt install libbluetooth-dev bluetooth blueman bluez libusb-dev libdbus-1-dev bluez-hcidump bluez-tools
```
5. [on RPi] For Gstreamer1.0 support
```
sudo apt-get install gstreamer1.0-omx libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
```
6. [on RPi] Prepare our target directory
```
sudo mkdir /usr/local/qt5pi
sudo chown pi:pi /usr/local/qt5pi
```
7. [on Host] Create a sysroot. Using rsync we can properly keep things synchronized in the future as well. Replace raspberrypi.local with the address of the Pi.
```
mkdir sysroot sysroot/usr sysroot/opt
rsync -avz pi@raspberrypi.local:/lib sysroot
rsync -avz pi@raspberrypi.local:/usr/include sysroot/usr
rsync -avz pi@raspberrypi.local:/usr/lib sysroot/usr
rsync -avz pi@raspberrypi.local:/opt/vc sysroot/opt
```
8. [on Host]build configuration:
```
../configure -release -no-eglfs -qt-xcb -xcb -nomake tests -nomake examples -skip wayland -skip qtscript -skip qtwebengine \
-device linux-rasp-pi3-g++ \
-device-option CROSS_COMPILE=/media/mehran/extra3/Qt5Pi3X11/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- \
-sysroot /media/mehran/extra3/Qt5Pi3X11/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi \
-extprefix /media/mehran/extra3/Qt5Pi3X11/raspi/qt5pi -hostprefix /media/mehran/extra3/Qt5Pi3X11/raspi/qt5 -v -no-use-gold-linker
```
9. [on RPI] Fix Could not initialize egl display for EGLFS
```
cd /opt/vc/lib
sudo ln -s libbrcmEGL.so libEGL.so.1
sudo ln -s libbrcmGLESv2.so libGLESv2.so.2
export LD_LIBRARY_PATH=/opt/vc/lib
```
