-updated for Linux on 03/01/2013
-
-get the source version through svn :
-
-svn co https://pure-data.svn.sourceforge.net/svnroot/pure-data pure-data
-cd pure-data/trunk/externals/pix_opencv
-
-you need a working build toolchain
-
-pix_opencv depends on OpenCV 2.x and >1.5 (for old externals)
-
-===== GNU/Linux ===== 
-
-# (actually only tested in GNU/Linux Ubuntu)
-# this new version requiered OpenCV 2.3, available with apt-get since 12.04 :
-apt-get install libopencv-dev
-
-# for other systems, you can build the lib from source, see this :
-# http://opencv.willowgarage.com/wiki/InstallGuide
-
-# get the source : 
-svn co https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/externals/pix_opencv pix_opencv
-
-cd pix_opencv
-make 
-
-# To use the binaries you can either put them into the same folder as your patch or to add this folder to the search paths of Pd
-
-===== MAC OSX (intel and powerPC) =====
-
-# install opencv with fink :
-fink install opencv-dev
-
-# if you don't have fink, you can build it from source by following this guide :
-# http://opencv.willowgarage.com/wiki/InstallGuide
-
-# then get the sources and compile :
-svn co https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/externals/pix_opencv pix_opencv
+1. Prepare you machine
+You need to have puredata and Gem installed on your system.
+And you need to know where they are…
+
+You also need a compiling toolchain, e.g. GCC on Linux/Mac or Microsoft Visual C++ on Windows.
+
+2. Get the sources :
+Download the pix_opencv sources from Puredata external repository :
+svn co svn://svn.code.sf.net/p/pure-data/svn/trunk/externals/pix_opencv
+or if you don't have svnl, can get a "snapshot",i.e. a zip file with the current code, here :
+https://sourceforge.net/p/pure-data/svn/HEAD/tree/trunk/externals/pix_opencv/
+
+3. Get opencv :
+Ubuntu/Linux
+The easiest way to get it is to install it from the repository :
+sudo apt-get install libopencv-*
+
+Mac OSX :
+The easiest way is to get from some packaging repository like Macports, fink or homebrew.
+with fink :
+sudo fink install opencv-dev
+with macport :
+sudo port install opencv
+
+Windows : 
+Download the binary release on opencv.org
+You can follow the quickstart guide on opencv.org to setup environment variables.
+
+4. Build the Sources :
+
+Ubuntu/Linux & MacOSX
+Go to the fresh created folder, i.e. « pix_opencv » and build the things :
 cd pix_opencv
-make PD_PATH=/path/to/pdextended-app/Contents/Resources/
-
-# PD_PATH should be ended by something like that : Pd-0.43.4-extended-20121231.app/Contents/Resources/
+make
+
+If you see something like « can’t find m_pd.h », you need to tweak pd’s path with this command :
+make --with-pd=/path/to/pd
+If you see something like « can’t find Base/GemPixObj.h », you need to tweak Gem’s path with this command :
+make --with-gem=/path/to/gem
+You can combine options like :
+make --with-pd=/path/to/pd --with-gem=/path/to/gem
+
+Windows
+You need Visual C++ (at least the free express edition) to build pix_opencv on Windows.
+There is a solution in build/vs2010 folder.
+It was made with Visual C++ Express 2010 and surely need some tweaks before producing any DLL.
+You need to change the include and the library paths.
+The include must contain the following :
+  - puredata include (pd-extended) or src (vanilla) folder : path\to\pd\src or path\to\pd-extended\include
+  - Gem include folder : path\to\Gem
+  - OpenCV include path, wich is ususally $(OPENCV_DIR)\..\..\include if you setup OPENCV_DIR according to Windows quickstart guide on opencv.org.
