[edit] Building on Mac OS X 10.6 Snow Leopard

Build succeeded using the following tools:

  • Compiler: GCC 4.2 (i686-apple-darwin10-gcc-4.2.1)
  • Build Path: SCons (part of blender sources)
  • SCons config: instructions on setting up user-config.py file found here: http://www.blender.org/forum/viewtopic.php?p=74897&highlight=#74897. (Everything needed seems to be in darwin-config.py, see instructions below. - Indy)
  • External library: FFTW3 (installed via MacPorts, see below) - Essential for fluid/smoke simulations

[edit] Dependencies

  • Install FFTW-3 via MacPorts 
sudo port install fftw-3 +universal

Make sure it says "Building fftw-3 for architecture i386". That's the 32bit version of FFTW3 for Blender.

[edit] Building Blender

This might be trivial, but here's how to get the most recent Blender sources: 

svn co https://svn.blender.org/svnroot/bf-blender/trunk bf-blender

You need to copy bf-blender/blender/config/darwin-config.py up one directory (bf-blender/blender) and rename as user-config.py. Then you change the flags at the very top to match your needs (some instructions here: http://www.blender.org/forum/viewtopic.php?p=74897&highlight=#74897). Don't actually change darwin-config.py.

FFTW3 32bit binaries aren't included in the SVN checkout. This is why you need to copy FFTW3 libraries and headers into the bf-blender/lib dir: 

mkdir -p ../lib/darwin-8.x.i386/fftw3/include
mkdir -p ../lib/darwin-8.x.i386/fftw3/lib

cp -a /opt/local/lib/libfftw3* ../lib/darwin-8.x.i386/fftw3/lib/
cp -a /opt/local/include/fftw3* ../lib/darwin-8.x.i386/fftw3/include/

Ready to bake the cake: 

python scons/scons.py

If everything went fine, the resulting blender.app will reside here: 

bf-blender/2.5-py3.1sl-build/darwin/bin/blender.app
