The QR-Code-generator package provides a QR code generator.
First unpack the CMake files:
tar -xf ../qrcodegen-cmake-1.8.0-cmake3.tar.gz &&
cp -vR qrcodegen-cmake-1.8.0-cmake3/{cmake,CMakeLists.txt} . &&
rm -rf qrcodegen-cmake-1.8.0-cmake3
Install QR-Code-generator by running the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=Release \
-D CMAKE_SKIP_INSTALL_RPATH=ON \
-D BUILD_SHARED_LIBS=ON \
-G Ninja .. &&
ninja
Now, as the root user:
ninja install
-D
CMAKE_SKIP_INSTALL_RPATH=ON: This switch makes
cmake remove
hardcoded library search paths (rpath) when installing a binary
executable file or a shared library. This package does not need
rpath once it's installed into the standard location, and rpath may
sometimes cause unwanted effects or even security issues.
-D BUILD_SHARED_LIBS=ON:
This ensures shared libraries are built.
