Failure to build QT5 5.12.3 on Raspberry Pi zero

Question

Following the instructions in https://www.tal.org/tutorials/building-qt-512-raspberry-pi,:

wget http://download.qt.io/official_releases/qt/5.12/5.12.3/single/qt-everywhere-src-5.12.3.tar.xz
tar xf qt-everywhere-src-5.12.3.tar.x

z git clone https://github.com/oniongarlic/qt-raspberrypi-configuration.git

cd into the clone repository and run (adjust DESTDIR in case your Qt sources are extracted somewhere else):

cd qt-raspberrypi-configuration && make install DESTDIR=../qt-everywhere-src-5.12.3

apt-get update
apt-get install build-essential libfontconfig1-dev libdbus-1-dev libfreetype6-dev libicu-dev libinput-dev libxkbcommon-dev libsqlite3-dev libssl-dev libpng-dev libjpeg-dev libglib2.0-dev libraspberrypi-dev

So for running the configure file i entered this command to terminal: export PATH="$PATH:/usr/lib/llvm-3.8

 sudo PKG_CONFIG_LIBDIR=/usr/lib/arm-linux-gnueabihf/pkgconfig:/usr/share/pkgconfig \
    ../qt-everywhere-src-5.12.3/configure -platform linux-rpi-g++ \
    -v \

    -force-pkg-config \
    -nomake examples -no-compile-examples \

    -fontconfig \
    -glib \
    -prefix /opt/Qt5.12 \
    -qpa eglfs \
    -qt-xcb

I have gone until the configure process so get this output:

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
On macOS, you can use Homebrew's llvm package.
On Windows, you must set LLVM_INSTALL_DIR to the installation path.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/opt/Qt5.12'.

Prior to reconfiguration, make sure you remove any leftovers from

and by running make -j2 i get this output:

My question link via Qt forum:

https://forum.qt.io/topic/103934/failure-to-build-qt5-5-12-3-on-raspberry-pi-zero

So, what can i do to solve this problem?

thanks

Answer 1

I've managed to build Qt5.12 on a pi-4.

I used the following script cobbled together from a couple of sources:

# Qt 5.12 build

# Different approach: https://github.com/plexydesk/cross-compile-tools/blob/master/build-qt5

#get source and configure repository

git clone git://code.qt.io/qt/qt5.git
cd qt5
git checkout 5.12
perl init-repository
cd ..

#setup for build
# needed for qdoc - can't get to work on rpi at the moment
# export LLVM_INSTALL_DIR=/usr/lib/llvm-9/

# build out of source
mkdir build_qt
cd build_qt
../qt5/configure -developer-build -opensource -confirm-license

make -j5
make -j5 module-qtscript
sudo make install
cd ..

export PATH=/opt/Qt5.12/bin/:$PATH
export LD_LIBRARY_PATH=/opt/Qt5.12/lib/:$LD_LIBRARY_PATH

You may need to install more packages then installed by the script for the build to work.

On a Pi-0 reduce the number of cores used to build.

You may have issues around OpenGL/EGL support on the Pi-0.

You will need to increase your swap space as amount of memory is only 512Mb.

Make sure you use a fast decent sized SD card.

Once you have Qt built and installed qtcreator build is straight forward.

NOTE: parts of Qt are licenced as GPL so if you are building a commercial app be careful to make sure you avoid these libraries/components.
