Introduction

Building Python-Ogre under OSX is a straight forward, if slightly lengthy process. However please don't expect it to be a classic UNIX/MAC build cycle as it's not. Python-Ogre is different in that it needs to build the underlying C/C++ libraries then create and compile the wrapper code. However all is not lost as there is a fairly simple build script and configuration that handles most of the complexity.

Note: we create all the libraries etc into the ./root/usr/... area so as to not overwrite any system libraries etc that you may have. Hence making the Python-Ogre build process a simple and "safe" one -- ie we never overwrite any system files or existing libraries.

What you need

• OS X version 10.6.x
• XCode 3.2

Step 1

On to our Python-Ogre install by creating a master development directory under your home directory and checkout Python-Ogre from the SVN. This may take a long time, go get some coffee.

cd ~
mkdir development
cd development
svn co http://python-ogre.svn.sourceforge.net/svnroot/python-ogre/trunk/python-ogre python-ogre
curl http://54.org/alfred/python-ogre/OSXBuild10.6.patch | patch -p0 -N -d python-ogre

Step 2

Download and build the support libraries. We use a single build script (BuildModule.py) that can retrieve, build, generate wrapper code and compile the Python-Ogre modules (do a -h for more info or look at the script). It basically reads a set of commands from the environment.py script and executes them. By default all the logging is to log.out so if you have any problems have a look there.

python2.5 python-ogre/BuildModule.py -r -b cmake gccxml boost pygccxml scons pyplusplus ois ogre

Then run the demos by double-clicking the .app file in the Finder:

open ogre/Mac/build/Release

Step 3

Generate the wrapper code(-g), compile(-c) and install it

python2.5 python-ogre/BuildModule.py -g -c ogre ois
python2.5 python-ogre/BuildModule.py -b install

Testing by running demos

You can now run the Python-Ogre demos

export PYTHONPATH=~/development/root/usr/lib/python2.5/site-packages
export DYLD_LIBRARY_PATH=~/development/root/usr/lib
(cd python-ogre/demos/ogre; python2.5 Demo_Smoke.py)
(cd python-ogre/demos/ogre; python2.5 Demo_SkeletalAnimation.py)
