Pepper Plugins is needed to load Widevine later, and the codecs are needed to play media. webengine-pepper-plugins -webengine-proprietary-codecs -v \Ģ>&1 | tee. (This is rather hacky, I’ll explain below.)Īlso the build needs to happen in a separate directory. So we need to make sure the Mesa headers are found instead. To successfully build QtWebEngine, the Broadcom libraries shipped with the Pi are too old – they are missing GLES3 support, for example. >if we re-run this later, redo all test casesĬheck the output. >put binaries only used by the host machine here Now we are ready to configure Qt for build, that is everything but QtWebEngine for now (detailed explanation on the right): cd /opt/qt5pi/sysroot/usr/lib/arm-linux-gnueabihf/pkgconfig/

pc files so configure falls back on our definitions instead of using the (mesa) defaults. Actually, there usually are multiple methods, the last of which is using the static definitions from nf we just set. Qt uses pkg-config to determine whether some library is installed (on the Pi) and where. QMAKE_CFLAGS = -march=armv8-a -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 QMAKE_LIBDIR_OPENGL_ES2 = $$ -lbcm_host -lvcos -lvchiq_arm -pthread Required for EGL config.test (at least) because brcmGLESv2 also needs brcmEGL. # This way you can make mesa headers available by manually removing directories EGL, GLES and GLES2 from /opt/vc/include before building. # Including headers from /opt/vc first, but also from mesa version of EGL and GLES, since the /opt/vc headers are from 2009 and don't work with qtwebengine. # The reason for using static values instead of supplying the correct pkg-config files is that configure ignores -pthread from there # Remove egl.pc and glesv2.pc from /usr/lib/arm-linux-gnueabihf/pkgconfig/ for these to take effect. # Also setting the linker flags according to the pkg-config files that are shipped with the libraries. # MODIFIED to use the library names that are shipped since 2016 It should look like this: # qmake configuration for the Raspberry Pi 3 using the Broadcom graphics stack This file defines some settings for compilation and is a modification of the one provided by Qt. (d) If I already did checkout a branch for which there are newer commits:Ĭp -r linux-rasp-pi3-g++/ linux-rasp-pi3-brcm-g++/ If I want one newer than this, I have to checkout a branch of qtwebengine: (c) Normally some specific commit of QtWebEngine is selected in the super repository. (a) I want to stay in the same branch (5.15) and pull more recent changes:

Update Qt source code (unless you just got it).These contain libraries, headers and pkg-config files we will need later. This will copy the specified directories from your Pi over the network into a directory called sysroot.
Rsync -avzR :/usr/include :/usr/lib :/usr/share/pkgconfig/ :/opt/vc sysroot Get the (updated) sysroot from your Pi and make symlinks relative.Run these steps next or every time you want to update your Qt. You can read up on all available modules here and find out more about the tool with init-repository -help or here. Here we specify all essential modules and QtWebEngine to be downloaded. The “super-repo” by itself is tiny, and everything else is kept as git submodules. Init-repository is a convenience tool provided by Qt to fetch the source code of the specified modules. contain security patches for chromium earlier. When checking out a branch I prefer 5.15 over let’s say 5.15.0, because 5.15 will receive more/newer updates, and i.e.

I prefer using the git repo over the qt-everywhere download because it is more modular and easier to update. init-repository -module-subset=essential,qtwebengine This is just a handy tool by someone on Github that we will need later to turn absolute symbolic links into relative ones. Feel free to always pick the newest one, it should work just fine as C++ is rather strict on backwards compatibility. is extremely outdated and uses gcc 4.8, so use one provided by linaro. Sudo chown 1000:1000 /opt/raspiToolchains

Sudo apt-get install g++-multilib python pkg-config gperf bison flex libnss3-dev Mesa version of the graphics drivers, including headers. Sudo apt install libfontconfig1-dev libdbus-1-dev libnss3-dev libxkbcommon-dev libjpeg-dev libasound2-dev libudev-dev libgles2-mesa-dev

The whole graphics driver situation is quite complicated, and I will try to explain it below, but first, my step-by-step guide: This is how I cross-compiled Qt 5.15 including QtWebEngine for a Raspberry Pi 3 utilizing the default Broadcom graphics libraries supplied by RaspiOS.
