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. |
