# qmake configuration for the Raspberry Pi 4 (32-bit) using the Mesa V3D
# graphics stack. (not the Broadcom stack)
#
# This supports accelerated OpenGL both for X11 and DRM/KMS. Perhaps
# Wayland too.
#
# Tested with a sysroot created from Raspbian Buster and a gcc 7.4
# toolchain from Linaro.
#
# Example configure command line, assuming installation to
# /usr/local/qt5pi on device and ~/rpi/qt5 on the host:
#
# ./configure -release -opengl es2 -device linux-rasp-pi4-v3d-g++ -device-option CROSS_COMPILE=~/rpi/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- \
# -sysroot ~/rpi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/rpi/qt5 -v
#
# Check the configure output carefully. EGLFS, EGLFS GBM, and EGL on X11
# should all be 'yes'. Otherwise something is wrong.
#
# If getting linker errors like "undefined reference to `_dl_stack_flags'" check the
# symlinks in the sysroot, they were probably not adjusted
# correctly. F.ex. sysroot/usr/lib/arm-linux-gnueabihf/libpthread.so must point to
# sysroot/lib/arm-linux-gnueabihf/libpthread.so.0. If it is a broken link instead, bad
# things will happen.
