Hello,
I have just got my Raspberry Pi3 (using raspbian lite without pixel -
only linuxfb/eglfs) and I am having problems to run Qt3d examples (which
will be very useful to for me). I cross compiled Qt5.8 library
downloaded from download.qt.io using this tutorial
https://wiki.qt.io/RaspberryPi2EGLFS. Everything went just fine, I only
used another configure options:
-opengl es2 -optimized-qmake -no-pch -make libs -make tools
-reduce-exports -sysroot /home/lukas/raspberry/sysroot -device
linux-rasp-pi2-g++ -device-option
CROSS_COMPILE=/home/lukas/raspberry/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-
-prefix /usr/local/rasp -opensource -nomake examples -nomake tests
-confirm-license -skip qtmultimedia -skip qtcharts -skip qtsensors -skip
qtgamepad -skip qtmacextras -skip qtandroidextras -skip qtwayland
-prefix /usr/local/qt5pi -extprefix /home/lukas/raspi/qt5pi -hostprefix
/home/lukas/raspi/qt5
Every qt3d example is compiled just fine, but when I run any of the
examples it is not working. Few examples look like everything working
just fine (I have also tried to enable logging by no error occurs) but
nothing is rendered. Few other examples are crashing on fragment shader
with error message:
Failed to link shader program: ERROR:OPTIMIZER-3 (fragment shader, line
41) Support for for loops is restricted : right side of condition
expression must be constant
Segmentation fault
My settings is:
- Raspberry Pi 3 using raspbian lite without pixel
- Host PC is Linux Mint 17.2 64bit
- I want to use qt3d without X11 or Wayland if possible!

Do I miss something? I have already tried same steps on Raspberry PiB+
but the result was just same.
Thanks for any answer.
