This is the documentation for RK3566 RK3568 RK3588 10.1inch 10.6inch 14inch 15.6inch Tablet products, written by RSD Team of HYY Technology Co.,Ltd.

How we config qt5.14.2

How we config build support gstreamer 1.0

  1. install build tools on target board [RK3588 Mainboard (SBC)]
sudo apt-get install g++-aarch64-linux-gnu on target board
  1. Downloard QT qt-everywhere-src-5.14.2.tar.xz and uncompress
tar xvf qt-everywhere-src-5.14.2.tar.xz
  1. install gstreamer packages on target board [RK3588 Mainboard (SBC)]
sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools
sudo apt-get install libunwind-dev
  1. Check gstreamer installed on target board [RK3588 Mainboard (SBC)]
pkg-config gstreamer-1.0 --cflags
-pthread -I/usr/include/gstreamer-1.0 -I/usr/include/aarch64-linux-gnu -I/usr/include/glib-2.0 -I/usr/lib/aarch64-linux-gnu/glib-2.0/include

pkg-config gstreamer-1.0 --libs
-lgstreamer-1.0 -lgobject-2.0 -lglib-2.0
  1. gstreamer 1.0 will failed if have no libgstreamer-plugins-base1.0-dev when do configure check on target board [RK3588 Mainboard (SBC)]
sudo apt install libgstreamer-plugins-base1.0-dev
  1. How we config build support ALSA
sudo apt-get install libasound2-dev
  1. Do config check on target board [RK3588 Mainboard (SBC)] as below:
./configure -release -opensource -confirm-license -gstreamer 1.0

will show as below:

Qt Multimedia:
  ALSA ................................... yes
  GStreamer 1.0 .......................... yes
  GStreamer 0.10 ......................... no
  Video for Linux ........................ yes
  OpenAL ................................. no
  PulseAudio ............................. no
  Resource Policy (libresourceqt5) ....... no
  Windows Audio Services ................. no
  DirectShow ............................. no
  Windows Media Foundation ............... no
  1. Sync sysroot from target board [RK3588 Mainboard (SBC)] to host for cross-compile
mkdir sysroot sysroot/usr sysroot/opt
rsync -avz hyy@hyytarget:/lib sysroot
rsync -avz hyy@hyytarget:/usr/include sysroot/usr
rsync -avz hyy@hyytarget:/usr/lib sysroot/usr
  1. How we config qmake.conf on Host
cd /media/admin_/RK3568SDK/shadow_build_qt_5.14.2/qtbase/mkspecs/
mkdir linux-arm-som-rk3568
cp linux-aarch64-gnu-g++/* linux-arm-som-rk3568/
