G'day, I've attempted cross-compiling Qt for Raspberry Pi 2/3 on my Ubuntu machine, trying each and every tutorial I've found online. I've had issues with each approach, and have decided to compile Qt natively on the Pi itself for simplicity. Unfortunately, all the native RPi Qt compiling tutorials I've attempted have caused issues as well (I don't have any error outputs on hand, but can provide them if need be). Can someone point me to a step-by-step that will allow me to build Qt on a Raspberry Pi 2/3? I'm weary of the age of some of the tutorials I've attempted (~2015), so a more recent tutorial would be greatly appreciated. Once Qt is configured correctly on the RPi, I will be attempting to build PyQt5 on the RPi as well. My only requirement is to run PyQt5-based .py files in fullscreen mode without an X server (EGLFS, etc.) Any input would be greatly appreciated! Thanks

For cross-compilation, this is by far the best tutorial: https://wiki.qt.io/RaspberryPi2EGLFS . The only thing that is missing from there, is that you have to disable gold linker in configure: -no-use-gold-linker. If you want to build natively, this should work: sudo apt-get build-dep qt5-default sudo apt-get install libiconv-hook-dev libinput-dev libts-dev bluez libbluetooth-dev libgstreamer1.0-dev libegl1-mesa # extract Qt to 5.9.0-src mkdir 5.9.0-bin 5.9.0-build cd 5.9.0-build ../5.9.0-src/configure -prefix $PWD/../5.9.0-bin -confirm-license -opensource -nomake examples -skip qtwebview -skip qt3d -skip qtquick1 -skip qtwayland -skip qtvirtualkeyboard -skip qtwebchannel -skip qtwebengine -no-use-gold-linker -opengl es2 make -j 5 make install Your Qt will be installed to 5.9.0-bin folder (the other 2 dirs can be removed). QtBase can be compiled this was 100%. For GUI parts... you'll have to check. If it fails, try the raspberry pi 3 makespecs (but you will have to tweak it a bit, because it was prepared for cross compilation).

G'day,

I've attempted cross-compiling Qt for Raspberry Pi 2/3 on my Ubuntu machine, trying each and every tutorial I've found online. I've had issues with each approach, and have decided to compile Qt natively on the Pi itself for simplicity.

Unfortunately, all the native RPi Qt compiling tutorials I've attempted have caused issues as well (I don't have any error outputs on hand, but can provide them if need be). Can someone point me to a step-by-step that will allow me to build Qt on a Raspberry Pi 2/3? I'm weary of the age of some of the tutorials I've attempted (~2015), so a more recent tutorial would be greatly appreciated.

Once Qt is configured correctly on the RPi, I will be attempting to build PyQt5 on the RPi as well. My only requirement is to run PyQt5-based .py files in fullscreen mode without an X server (EGLFS, etc.)

Any input would be greatly appreciated!

Thanks
