This script builds Blender from its source code, rather than repackaging an existing binary version. The process is therefore more complex and time consuming but allows finer tuning of capabilities of the resulting package. Working through the prerequisite packages from the REQUIRES field of Blender.info results in the following basic build order: multimedia/ffmpeg audio/jack libraries/opencv graphics/opencollada libraries/OpenAL python/python3 python/python-requests development/valgrind libraries/libwebp development/numpy3 development/SDL2 graphics/opencolorio graphics/openimageio libraries/freealut graphics/Blender When generating a new build order, python3 should first be added to the REQUIRES field of python-requests.info. To facilitate the greatest utility for Blender, its is strongly suggested that a number of standard SBo packages be built with a more complete set of features than provided by the default scripts: 1. the opencv package could/should first be built with additional features by preinstalling some other packages e.g. REQUIRES=" opencl-headers libjpeg-turbo ffmpeg Sphinx libdc1394 numpy3 gtkglext tbb jdk " The cmake configuration in opencv.SlackBuild can be replaced with: cmake \ -DCMAKE_C_FLAGS="$SLKCFLAGS" \ -DCMAKE_CXX_FLAGS="$SLKCFLAGS" \ -DCMAKE_BUILD_TYPE="Release" \ -DCMAKE_INSTALL_PREFIX=/usr \ -DBUILD_SHARED_LIBS=ON \ -DENABLE_PRECOMPILED_HEADERS=OFF \ -DLIB_SUFFIX=$LIBDIRSUFFIX \ -DWITH_TBB=ON \ -DWITH_OPENCL=ON \ -DWITH_OPENGL=ON \ -DWITH_QT=ON \ -DWITH_XINE=ON \ -DBUILD_EXAMPLES=ON \ -DINSTALL_C_EXAMPLES=ON \ -DINSTALL_PYTHON_EXAMPLES=ON \ -DBUILD_NEW_PYTHON_SUPPORT=ON \ -DWITH_FFMPEG=ON \ -DCMAKE_SKIP_RPATH=ON \ -DWITH_1394:BOOL=ON \ .. If resources allow, the very large cudatoolkit package is another possible package which may be preinstalled and be utilised by the opencv build process. Blender itself can also use cudatoolkit to provide GPU rendering in systems with NVidia GPU cards. In this case, the SlackBuild will enable CUDA support if a cudatoolkit installation is detected at build time. In the unlikely CUDA support is not wanted despite cudatoolkit being available at build time, set the CUDA environment variable to "no" when running the SlackBuild e.g. CUDA=no sh ./Blender.SlackBuild 2. the ffmpeg package could/should first be built with additional features by preinstalling some other packages e.g. REQUIRES="lame x264 speex libbluray xvidcore OpenAL libmodplug frei0r libdc1394 libavc1394 libiec61883 ladspa_sdk gsm rtmpdump libva twolame celt faac dirac schroedinger" 3. the numpy SlackBuild at SBo does not build the python3 modules which are needed to be useful for any numpy-related python scripting in blender. It is therefore numpy3 which is the prerequisite for this build of blender.
