These indications are for Windows. If you use Linux/MacOSX, see build page.

We will use TortoiseSVN for repository access and patch application. Examples are given with screenshots using the GUI version of TortoiseSVN, but you can achieve same result using command-line (in any case, its a good idea to install command-line tools of svn when installing TortoiseSVN).

Using TortoiseSVN contextual menu in your BlenderWorkspace directory, check-out https://webdev.limsi.fr/svn/blenderCAVE/trunk (the trunk or a specific releases/X.Y release of blenderCave you need) into a blenderCave_svn/ directory:

Wait until it is completly downloaded.

You must download the sources of the blender version corresponding to the downloaded blenderCave patch version. You can find that version number in the patch filename: blenderCave_svn/patch/blender_revision_xxxxx.patch.

You can find this version on blender web site

Then unzip it inside the C:\BlenderWorkspace\blender-src\.

Using TortoiseSVN contextual menu on blender_src/ directory, select submenu TortoiseSVN then submenu Apply patch….

Select the patch file from blenderCave_svn/patch/ directory.

When the list of patched files is opened, click “Patch all items”.

When finished, if you update your Windows Explorer, you can see that blender_src/ directory is marked dirty by TortoiseSVN (because its patched).

We use Visual Studio Express 2013 for Windows Desktop.

Download ad-hoc revision of precompiled libraries for Visual Studio 2013 64 bits under Windows, from svn repository https://svn.blender.org/svnroot/bf-blender/trunk/lib/win64_vc12/ and install it into BlenderWorkspace\lib\win64_vc12.

Beware to select the revision 61323. The others include wrong libraries.

Within CMake, select Unix makefile.

Follow the build procedure (adapted to our paths). Here are some notes from our build experience.

We used mingw-get-setup from MinGW site.

CMake failed to find numpy, we installed Python 3.3 from Python site (for win32) in standard C:\Python33\ directory (with PATH modification to find it on command line), and Numpy for Python 3.3, then we adapted CMakeLists.txt to target this Python installation:

Missing pthread library – it was not installed with standard MinGW install – can be installed via gui interface, selecting mingw32-pthreads-w32 dev package:

Or via the command line with:

mingw-get install mingw32-pthreads-w32-dev

Command to build the project, within C:\BlenderWorkspace\blender_build\ directory:

mingw32-make
