Configure, Build, Install & Setup Qt 5.15.2 Source on Ubuntu 18.04 with X11 Support
This tutorial will teach you how to compile from source via CLI (command-line interface) and enable customization for building Qt5 apps on different operating systems andor hardware architectures like RPI400.
When compiling Qt5 yourself, you are empowered with a configuration that is constant throughout the Linux Universe. This process is also very similar with compiling Qt apps on your (AArch64) ARM64 devices like RPi 400, Rock64 & PineBook64.
Note: This tutorial doesn't include json Qtwebengine
What is Qt?
"Qt is a cross-platform application development framework for desktop, embedded and mobile." [Qt Wiki]
Let's Begin!
Remove & purge all Qt packages
sudo apt -y remove qt5* libqt5* qtcreator && sudo apt autoremove
Download Qt 5.15.2 Source to qt5-sources folder
mkdir qt5-sources && cd qt5-sources && mkdir build-shadow
wget https://download.qt.io/official_releases/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.tar.xz
Verify MD5 hash
md5sum qt-everywhere-src-5.15.2.tar.xz
e1447db4f06c841d8947f0a6ce83a7b5 qt-everywhere-src-5.15.2.tar.xz
Un-tar Qt5 archive
tar xf qt-everywhere-src-5.15.2.tar.xz
Move into build-shadow directory to configure your Qt 5.15.2
cd build-shadow
Install Qt5 Minimal Dependencies
sudo apt update
sudo apt 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
(Optional) Install VC4 Drivers for RPi 4 type devices (i.e. cortex-a53 & cortex-a72)
sudo apt install libgles2-mesa-dev libgbm-dev libdrm-dev
Install X11 Support Dependencies
sudo apt install libx11-dev libxcb1-dev libxext-dev libxi-dev libxcomposite-dev libxcursor-dev libxtst-dev libxrandr-dev libfontconfig1-dev libfreetype6-dev libx11-xcb-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-util0-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev
Configure Qt 5.15.2
../qt-everywhere-src-5.15.2/configure -v -bundled-xcb-xinput -opensource -confirm-license -release -ssl -glib -no-feature-geoservices_mapboxgl -qt-pcre -nomake examples -no-compile-examples -nomake tests -reduce-exports -system-freetype -fontconfig -qpa xcb
Make the configuration (-j 4 is number of cpus you want to use)
make -j 4
Install Qt5 into: (default) /usr/local/
sudo make install
Note: Check and make sure ./configure has required deps; if you installed the deps, but still receiving errors, remove config.cache and ./configure again.
Tip: If you want to view your configuration summary, you may do so via nano config.summary from build-shadow directory
Update profile to know where Qt5.15.2 bins are
nano ~/.bashrc
Add this at the bottom of your .bashrc file.
# set PATH for Qt 5.15.2
export PATH="/usr/local/Qt-5.15.2/bin:$PATH"
Reload your ~/.bashrc file & create new shell window.
source ~/.bashrc
CTRL+SHIFT+T
ALT+1
exit
Verify Qt 5.15.2 has been installed
qmake --version
QMake version 3.1
Using Qt version 5.15.2 in /usr/local/Qt-5.15.2/lib
Build your happy Qt5 app
./build.sh
