====== blendreCave Windows build ======

<note warning>This version is not up to date !</note>

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

<note tip>To ease further references, lets suppose we work in a folder named ''C:\BlenderWorkspace''. Any file or directory creation, if not mentioned otherwise, takes place in that folder.</note>

We will use [[http://tortoisesvn.net/|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).

===== Download blenderCave sources =====

<note important>**Next blenderCave version coming**

We are on the way of realeasing blenderCave 3.6 (latest is 3.2, intermediate releases are for internal use) --  it will be downloadable when ready.
</note>

==== From LIMSI ====

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:

{{ :doc:checkout_blendercave.png?nolink |Checkout blendercave}}

Wait until it is completly downloaded.

{{ :doc:checkout_blendercave_finished.png?nolink&500 |Checkout blendercave finished}}

===== Download blender sources =====

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 [[http://www.blender.org/download/|blender web site]]

Then unzip it inside the ''C:\BlenderWorkspace\blender-src\''.
===== Apply the patch =====

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

{{ :doc:tortoise_svn_apply_patch.png?nolink |TortoiseSVN apply patch command}}

Select the patch file from ''blenderCave_svn/patch/'' directory.

{{ :doc:tortoise_select_patchfile.png?nolink |Selection of blenderCave patch file}}

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

{{ :doc:tortoise_select_patched_files.png?nolink |Patch all blender files}}

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

{{ :doc:blender_source_dirty.png?nolink |Blender source is patched}}


===== Compile patched blender =====

==== Install compiler and build tools ====

We use [[http://www.visualstudio.com/en-us/products/visual-studio-express-vs.aspx|Visual Studio Express 2013 for Windows Desktop]].
==== Download precompiled libraries ====
 
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.

{{ :doc:checkout-precompiled-libs.png?nolink |Checkout precompiled libs for MinGW-w64 under Windows}}

==== Prepare makefiles ====

Within CMake, select Unix makefile.

Follow the [[http://wiki.blender.org/index.php/Dev:Doc/Building_Blender/Windows/MinGW/CMake|build procedure]] (adapted to our paths). Here are some notes from our build experience.

We used [[http://sourceforge.net/projects/mingw/files/latest/download|mingw-get-setup]] from [[http://www.mingw.org/|MinGW]] site.

CMake failed to find numpy, we installed [[https://www.python.org/downloads/|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:

{{ :doc:mingw32-pthread-library.png?nolink |Install MingGW pthread library dev files}}

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
