% Tested on Ubuntu 20.04.4 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS and
|
|
% Fedora Linux 41 (Workstation Edition)
|

|
|
1. Prerequisites for building zint
|
|
==================================
|
|
|
|
Prerequisites are git, cmake, make, gcc and gcc-c++, e.g. Ubuntu/Debian
|
|
|
|
sudo apt install git cmake build-essential
|
|
|
|
or Fedora (git, make and gcc should already be installed)
|
|
|
|
sudo dnf install cmake gcc-c++
|
|
|
|
libpng is optional but necessary for PNG support, e.g. Ubuntu/Debian
|
|
|
|
sudo apt install libpng-dev
|
|
|
|
or Fedora
|
|
|
|
sudo dnf install libpng-devel
|
|
|
|
Then either download the source code tarball
|
|
|
|
wget -O zint-2.15.0-src.tar.gz \
|
|
https://sourceforge.net/projects/zint/files/zint/2.15.0/zint-2.15.0-src.tar.gz/download
|
|
tar xf zint-2.15.0-src.tar.gz
|
|
cd zint-2.15.0-src
|
|
|
|
or clone the latest source
|
|
|
|
git clone https://git.code.sf.net/p/zint/code zint
|
|
cd zint
|
|
|
|
|
|
2. Prerequisites for building zint-qt
|
|
=====================================
|
|
|
|
zint-qt can be built with either Qt5 (preferred) or Qt6. First, install mesa (for OpenGL), e.g.
|
|
Ubuntu/Debian
|
|
|
|
sudo apt install mesa-common-dev libglu1-mesa-dev
|
|
|
|
or Fedora
|
|
|
|
sudo dnf install mesa-libGL mesa-libGL-devel
|
|
|
|
zint-qt has issues running on Wayland so sets X11 as the Qt platform (via the environment variable
|
|
"QT_QPA_PLATFORM=xcb") on startup unless already set.
|
|
|
|
2.1. Using Qt packages
|
|
----------------------
|
|
|
|
If packages for Qt exist for your distro, it might be easiest to use them, although knowing
|
|
what their ever-changing names and contents are isn't. A complication is that zint-qt uses 2 Qt
|
|
components beyond the basic setup: Qt UI Tools (for dynamically loading the symbology-specific
|
|
tabs), and Qt SVG (for rendering icons).
|
|
|
|
E.g. on Ubuntu 22.04 or 24.04
|
|
|
|
sudo apt install qtbase5-dev qttools5-dev qttools5-dev-tools libqt5svg5-dev
|
|
|
|
or Ubuntu 20.04
|
|
|
|
sudo apt install qt5-default qt5-uitools
|
|
|
|
or Fedora (not recommended)
|
|
|
|
sudo dnf install qt5-qtbase-devel qt5-qttools-devel qt5-qttools-static qt5-qtsvg-devel
|
|
|
|
You may need to tell CMake where to find the ".cmake" modules:
|
|
|
|
export CMAKE_MODULE_PATH=<cmake-module-path>/Qt5
|
|
|
|
e.g. CMAKE_MODULE_PATH=/usr/lib/x86_64-linux-gnu/cmake/Qt5
|
|
|
|
2.2. Using the Qt Maintenance Tool
|
|
----------------------------------
|
|
|
|
Alternatively, for a more consistent experience, sign up and download the Qt Maintenance Tool
|
|
from
|
|
|
|
https://www.qt.io/download-qt-installer
|
|
|
|
On Ubuntu/Debian you may need to install xinerama to run the tool:
|
|
|
|
sudo apt install libxcb-xinerama0
|
|
|
|
Launch the tool and install the "Desktop gcc 64-bit" component for either Qt 5.15.2 (preferred)
|
|
or Qt 6 (>= 6.1).
|
|
|
|
Once Qt is installed you may need to tell CMake where it is:
|
|
|
|
export CMAKE_PREFIX_PATH=<qt-version-dir>/gcc_64
|
|
|
|
e.g. export CMAKE_PREFIX_PATH=/opt/Qt/5.15.2/gcc_64
|
|
|
|
|
|
3. Build
|
|
========
|
|
|
|
The rest is standard CMake
|
|
|
|
cd zint
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
make
|
|
sudo make install
|
|
|
|
4. Run
|
|
======
|
|
|
|
On Fedora you may have to set LD_LIBRARY_PATH for zint ("libzint.so") and zint-qt (Qt libraries):
|
|
|
|
export LD_LIBRARY_PATH=/usr/local/lib64:<qt-version-dir>/gcc_64/lib
|
|
|
|
|
|
5. CMake options
|
|
================
|
|
|
|
A number of options are available:
|
|
|
|
ZINT_COVERAGE:BOOL=OFF # Set code coverage flags
|
|
ZINT_DEBUG:BOOL=OFF # Set debug compile flags
|
|
ZINT_FRONTEND:BOOL=ON # Build frontend
|
|
ZINT_NOOPT:BOOL=OFF # Set no optimize compile flags
|
|
ZINT_SANITIZE:BOOL=OFF # Set sanitize address/undefined
|
|
ZINT_SANITIZEM:BOOL=OFF # Set sanitize memory (ignored if ZINT_SANITIZE)
|
|
ZINT_SHARED:BOOL=ON # Build shared library
|
|
ZINT_STATIC:BOOL=OFF # Build static library
|
|
ZINT_TEST:BOOL=OFF # Set test compile flag
|
|
ZINT_UNINSTALL:BOOL=ON # Add uninstall target
|
|
ZINT_USE_PNG:BOOL=ON # Build with PNG support
|
|
ZINT_USE_QT:BOOL=ON # Build with Qt support
|
|
ZINT_QT6:BOOL=OFF # If ZINT_USE_QT, use Qt6
|
|
|
|
which can be set by doing e.g.
|
|
|
|
cmake -DZINT_SANITIZE=ON ..
|
|
|
|
Note that ZINT_SANITIZEM (Clang only) is incompatible with ZINT_SANITIZE, and also with
|
|
ZINT_USE_PNG, unless libpng has also been instrumented with -fsanitize=memory.
|
|
|
|
