My Development Setup

I have several machines I switch between when developing for Blender. Some machines I have at home and I have a machine at the Blender Institute for the work I perform there. Basically all those machines have a ubuntu 18.04 installed. I also have a dual boot to run Windows, but I only use that to fix AMD/WIntel related issues in the 3d viewport.


As main IDE I use Visual Studio Code with the next plugins

  • C/C++ - Microsoft
  • C/C++ Clang Command Adapter - Yasuaki MITANI
  • Clang-Format - caver
  • Code Spell Checker - Street Side Software
  • RST Preview - homas Haakon Townsend
  • Shader language support for VS Code - slevesque

GPU development

  • renderdoc Need to know what is going on inside a specific GPU task. This tool will give you insight in the commands, input data, output data and pipeline status. Useful to detect issues when developing OpenGL or doing driver support.

Ninja build system

Bare instructions to build blender using the ninja build system. The build system is supported by CMake, but when using blender there are still some rough edges that needs to be dealt with. The next steps are how I setup the ninja build system to compile Blender.

The nice time saver when using ninja is the condensed warning/error output when compiling. If something is right it doesn't show it. When developing Blender without this you sometimes need to scroll several hundred lines of output to figure out what the actual error is.

sudo apt-get install ninja-build
cd blender-git
rm -Rf build_linux
cd blender

Add -G Ninja to the BUILD_CMAKE_ARGS and use make ninja for example.

make ninja -j8 BUILD_CMAKE_ARGS="-G Ninja -U *SNDFILE* -U *PYTHON* -U *BOOST* -U *Boost* -U *OPENCOLORIO* -U *OPENEXR* -U *OPENIMAGEIO* -U *LLVM* -U *CYCLES* -U *OPENSUBDIV* -U *OPENVDB* -U *COLLADA* -U *FFMPEG* -U *ALEMBIC* -D WITH_CODEC_SNDFILE=ON -D PYTHON_VERSION=3.7 -D WITH_OPENCOLORIO=ON -D OPENCOLORIO_ROOT_DIR=/opt/lib/ocio -D WITH_OPENIMAGEIO=ON -D OPENIMAGEIO_ROOT_DIR=/opt/lib/oiio -D WITH_CYCLES_OSL=ON -D WITH_LLVM=ON -D LLVM_VERSION=6.0 -D OSL_ROOT_DIR=/opt/lib/osl -D WITH_OPENSUBDIV=ON -D OPENSUBDIV_ROOT_DIR=/opt/lib/osd -D WITH_OPENVDB=ON -D WITH_OPENVDB_BLOSC=ON -D OPENVDB_ROOT_DIR=/opt/lib/openvdb -D BLOSC_ROOT_DIR=/opt/lib/blosc -D WITH_ALEMBIC=ON -D ALEMBIC_ROOT_DIR=/opt/lib/alembic -D WITH_CODEC_FFMPEG=ON -D FFMPEG_LIBRARIES='avformat;avcodec;avutil;avdevice;swscale;swresample;lzma;rt;theora;theoradec;theoraenc;vorbis;vorbisenc;vorbisfile;ogg;x264;openjp2'"

Both changes are needed otherwise one for initializing the ninja build system and the other to compile using ninja.

I would propose that this can be streamlined a bit. Go into your build folder and start the ninja build.
