Unsolved cross-compiling Qt 5.6 for HW accelerated OpenGL with eglfs on Raspbian Jessie

[carter_james]

my configure script :
./configure -release -opengl es2 -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=/home/raspberry/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot /home/raspberry/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix /home/raspberry/raspi/qt5pi -hostprefix ~/raspi/qt5 -v

how kann i fix broken symlinks ?

have a look at issue 6 from https://wiki.qt.io/RaspberryPi2EGLFS

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

my error:

The fixQualifiedLibraryPaths skript does not work well. the sysroot-relativelinks.py is working. Maybe the rsync was not succesfull. You have to pay attention on the rsync arguments. Especially make sure that there are no trailing backslashes in the path arguments.
