% Tested on FreeBSD 13.2-RELEASE (with X11 + GNOME installed) and OpenBSD 7.3 (with X11)
1. Prerequisites for building zint
==================================
Prerequisites are git, cmake, make, gcc (or clang) and, for PNG support, libpng, e.g. FreeBSD
su
pkg install git cmake gmake gcc graphics/png
exit
or OpenBSD (make and clang should already be installed):
su
pkg_add git cmake png
exit
Then clone the latest source
git clone https://git.code.sf.net/p/zint/code zint
cd zint
2. Prerequisites for building zint-qt
=====================================
On FreeBSD:
su
pkg install qt5-core qt5-uitools qt5-buildtools qt5-qmake qt5-svg
exit
On OpenBSD:
su
pkg_add qtbase qttools qtsvg
exit
3. Build
========
The rest is standard CMake (allowing for absence of sudo)
mkdir build
cd build
cmake ..
make
su
make install
exit
except that on OpenBSD you need to use
cmake -DCMAKE_PREFIX_PATH=/usr/local/lib/qt5/cmake ..
instead.
3. CMake options
================
See "README.linux". Note for running the test suite on FreeBSD, if using the default csh, to set LD_LIBRARY_PATH use:
setenv LD_LIBRARY_PATH ${PWD}/backend
Also, for Qt5 test on FreeBSD, need:
su
pkg install qt5-testlib
exit
