Raspbian Stretch 2017-11-29 + rpi-update
Description
I successfully cross compiled many Qt5 versions on Raspbian Wheezy and Jessie, but Stretch changed the availability of OpenGL drivers by having two GL options:
- Mesa VC4 driver (X11 dependent)
- Broadcom proprietary drivers (/opt/vc)
I need the BRCM EGFS cause I provide a headless solution without Xorg.
I followed the instructions here: http://wiki.qt.io/RaspberryPi2EGLFS
Item #14 is what should do the trick, but unfortunately it seems Qt is not looking in the right place. I keep on getting:
QPA backends: DirectFB ............................... no EGLFS .................................. yes EGLFS details: EGLFS OpenWFD ........................ no EGLFS i.Mx6 .......................... no EGLFS i.Mx6 Wayland .................. no EGLFS RCAR ........................... no EGLFS EGLDevice ...................... yes EGLFS GBM ............................ yes EGLFS Mali ........................... no EGLFS Raspberry Pi ................... no EGL on X11 ........................... yes LinuxFB ................................ yes VNC .................................... yes Mir client ............................. no X11: Using system-provided XCB libraries .. yes EGL on X11 ........................... yes Xinput2 .............................. yes XCB XKB .............................. yes XLib ................................. yes XCB render ........................... yes XCB GLX .............................. yes XCB Xlib ............................. yes Using system-provided xkbcommon ...... yes
Inspecting the config.tests/egl-brcm/Makefile shows the evidence:
############################################################################# # Makefile for building: egl-brcm # Generated by qmake (3.1) (Qt 5.9.4) # Project: egl-brcm.pro # Template: app # Command: /home/dragon/projects/rpi/qt-everywhere-opensource-src-5.9.4/qtbase/bin/qmake -o Makefile egl-brcm.pro 'CONFIG -= qt debug_and_release app_bundle lib_bundle' 'CONFIG += shared use_gold_linker warn_off console single_arch' 'QMAKE_CFLAGS += --sysroot=/mnt/rpi-rootfs' 'QMAKE_CXXFLAGS += --sysroot=/mnt/rpi-rootfs' 'QMAKE_LFLAGS += --sysroot=/mnt/rpi-rootfs' -early 'CONFIG += cross_compile' 'LIBS += -L/mnt/rpi-rootfs/usr/lib/arm-linux-gnueabihf -lEGL' 'QMAKE_CFLAGS += -I/mnt/rpi-rootfs/usr/include/libdrm' 'QMAKE_CXXFLAGS += -I/mnt/rpi-rootfs/usr/include/libdrm' 'LIBS += -lbcm_host' #############################################################################
It looks for headers and libs in /usr, instead of /opt/vc as requested in
qtbase/mkspecs/devices/linux-rasp-pi-g++/qmake.conf
The configure command line I'm providing is this:
./configure -opengl es2 -qpa eglfs -device linux-rasp-pi-g++ -device-option CROSS_COMP ILE=$BDIR/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot /mnt/rpi-rootfs -opensource -conf irm-license -optimized-qmake -reduce-exports -release -nomake tests -nomake examples -prefix /opt/qt5-rpi -no-pch -no-icu -gstreamer 1.0 -s kip qttools -skip qtwebengine -skip qtsensors -skip qtlocation -skip qtcanvas3d -skip qtxmlpatterns -skip qtcharts -skip qtdatavis3d
Is there any obvious trick I'm missing or is there something wrong in the GL driver detection ?
