Precompiled libraries

Mac OS: the necessary libraries are in our SVN: (https://svn.blender.org/svnroot/bf-blender/trunk/lib/darwin-9.x.universal/)

For Linux, use the new Script in SVN to compile the dependencies.

Windows: the libraries are in SVN too. (lib/windows and lib/win64)

Compile OSL on Linux

Note: This guide is only here for reference, to get Blender + OSL see above^^.

Requirements

Boost 1.49/1.50/1.51 (http://www.boost.org/)

OIIO 1.1 or higher (https://github.com/OpenImageIO/oiio)

OSL master or 1.3 (https://github.com/imageworks/OpenShadingLanguage)

LLVM 3.0 / 3.1 or Clang 3.1

flex, bison, can be installed from the Ubuntu Repository.

ATTENTION: Make sure you use right versions, as noted above. Especially important is use recent OSL and OIIO versions. Other versions probably won't work!!

Boost

Compile

./bootstrap.sh
 
./bjam -j4 variant=release link=static threading=multi --with-filesystem --with-thread --with-regex --with-system --with-date_time stage cxxflags=-fPIC

OpenImageIO

Go into the OIIO source folder.
Create the directory build/linux and cd into it.

Compile static libraries:

Replace /path_to_includes with your path to Boost includes (example: ./lib/linux64/boost/include)
Replace /path_to_libs with your path to Boost libs (example: ./lib/linux64/boost/lib)

cmake ../../src/ -DBUILDSTATIC=1 -DBOOST_CUSTOM=1 -DBoost_INCLUDE_DIRS=/path_to_includes -DBoost_LIBRARY_DIRS=/path_to_libs -DBoost_LIBRARIES="boost_date_time;boost_filesystem;boost_thread;boost_regex;boost_system" -DCMAKE_CXX_FLAGS=-fPIC -DCMAKE_INSTALL_PREFIX=`pwd`/../../dist/linux64

make install

Open Shading Language

Set environment variables for OIIO, BOOST and LLVM. Replace the example paths with the ones of the previously compiled libraries on your system.

export OPENIMAGEIOHOME=path/to/OIIO
export BOOST_HOME=path/to/BOOST
export LLVM_VERSION=3.0
export LLVM_DIRECTORY=path/to/LLVM

run "make cmakesetup"

ccmake ./build/linux64 (this path might be different on your OS)

Change the following options in cmake:

BUILDSTATIC=ON
LINKSTATIC=ON
BUILD_TESTING=OFF

run "make" again.

Blender

Copy all libs to the Blender libfolder (lib/linux64/), cmake should find them.

Set the following CMake options:

CYCLES_OSL=ON
WITH_LLVM=ON

After updating cmake you will currently have to change some options again (this is a bit stupid, will be fixed):

Set these to same values as in OSL:

LLVM_VERSION
LLVM_DIRECTORY

Then run cmake update again and build as usual.

Change the "Shading System" to "Open Shading Language" in the Properties Editor. Enjoy.
