%general-entities; ]> opencv The opencv package contains graphics libraries mainly aimed at real-time computer vision. &lfs120_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &opencv-md5sum; Download size: &opencv-size; Estimated disk space required: &opencv-buildsize; Estimated build time: &opencv-time; Additional Downloads Optional additional modules: One additional file that starts with "ippicv" (integrated performance primitives) will be automatically downloaded during the cmake portion of the build procedure. This download is specific to the system architecture. opencv Dependencies Required and Recommended , , , , , , , , , , , and Optional , , , , , ATLAS, blas, Cuda, Eigen, OpenEXR, GDAL, lapack, libdc1394, Threading Building Blocks (TBB), and VTK - The Visualization Toolkit, If you downloaded the optional modules, unpack them now: tar -xf ../opencv_contrib-&opencv-contrib-version;.tar.gz Install opencv by running the following commands: mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX=/usr \ -DCMAKE_BUILD_TYPE=Release \ -DENABLE_CXX11=ON \ -DBUILD_PERF_TESTS=OFF \ -DWITH_XINE=ON \ -DBUILD_TESTS=OFF \ -DENABLE_PRECOMPILED_HEADERS=OFF \ -DCMAKE_SKIP_RPATH=ON \ -DBUILD_WITH_DEBUG_INFO=OFF \ -Wno-dev .. && make The package does not come with a test suite. Now, as the root user: make install -DWITH_XINE=ON: This option instructs the make procedure to use . -DENABLE_PRECOMPILED_HEADERS=OFF: This option is needed for compatibility with gcc-6.1 and later. -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-&opencv-version;/modules: instructs the build system to build additional modules.
