If you want to skip the compilation process of both OpenCASCADE, GEOM, SMESH and pythonOCC, here are a few precompiled binaries.
Download and install the four following files:
- OpenCASCADE-MacOSX-SL-64.zip (105.5Mb) : extract the content to /Library. After that, you should have the folder /Library/OpenCASCADE/6.3.0/*
- GEOM-5.1.2.7-MacOsx-SL-64.zip (1.5Mb) : extract to /usr/local/lib. Check that the path /usr/local/lib/GEOM-5.1.2.7 contains libraries
- SMESH-5.1.2.2-MacOSX-SL-64.zip (1.2Mb) : extract to /usr/local/lib. Check that the path /usr/local/lib/SMESH-5.1.2.2 contains libraries
- pythonOCC-0.4-MacOSX-SL-64.zip (47.6Mb) : extract to /Library/Python/2.6/site-packages. Check that the path /Library/Python/2.6/site-packages/OCC/* exist
Before you can run pythonOCC, you have to care that a few env variables are defined. Add the following lines to your .bash_profile script :
# OpenCASCADE
export CASROOT=/Library/OpenCASCADE/6.3.0
export OCC_SOURCE_ROOT=${CASROOT}
export DYLD_LIBRARY_PATH=${CASROOT}/lib:$DYLD_LIBRARY_PATH
# needed to get the visualization going…
export CSF_GraphicShr=${CASROOT}/lib/libTKOpenGl.dylib
export CSF_EXCEPTION_PROMPT=1
# OCC required variables
export CSF_IGESDefaults=${OCC_SOURCE_ROOT}/src/XSTEPResource
export CSF_LANGUAGE=us
export CSF_MDTVFontDirectory=${OCC_SOURCE_ROOT}/src/FontMFT
export CSF_MDTVTexturesDirectory=${OCC_SOURCE_ROOT}/src/Textures
export CSF_PluginDefaults=${OCC_SOURCE_ROOT}/src/StdResource
export CSF_SHMessage=${OCC_SOURCE_ROOT}/src/SHMessage
export CSF_StandardDefaults=${OCC_SOURCE_ROOT}/src/StdResource
export CSF_StandardLiteDefaults=${OCC_SOURCE_ROOT}/src/StdResource
export CSF_STEPDefaults=${OCC_SOURCE_ROOT}/src/XSTEPResource
export CSF_UnitsDefinition=${OCC_SOURCE_ROOT}/src/UnitsAPI/Units.dat
# GEOM shared libraries
export DYLD_LIBRARY_PATH=/usr/local/lib/GEOM-5.1.2.7:$DYLD_LIBRARY_PATH
# SMESH shared libraries
export DYLD_LIBRARY_PATH=/usr/local/lib/SMESH-5.1.2.2:$DYLD_LIBRARY_PATH
Then, from a python console, just check the installation is ok (i.e. no linkage errors):
Python 2.6.1 (r261:67515, Jul 7 2009, 23:51:51)

Under MacOSX, unless you properly installed PyQt4-X11, you’ll need the python-xlib (0.15rc1 or higher) package in order to use the 3D viewer. You can now run the samples.

Hello,
I tried to follow these instructions and install pythonooc with python-xlib.
The simplest test
from OCC.Standard import * works.
all the other examples fail with
terminate called after throwing an instance of ‘Aspect_GraphicDeviceDefinitionError’
my own script fails with
could not open: FWOSPlugin ; reason: dlopen(libFWOSPlugin.dylib, 1): image not found
MSG:/Users/thomas/Devel/Salome/salomegeometry/tags/5.1.2_v7/src/GEOMImpl/GEOMImpl_IShapesOperations.cpp [142] : GEOMImpl_IShapesOperations::GEOMImpl_IShapesOperations
Have you heard of this one before? I’ve followed the OpenCascade forum instructions on the Aspect_GraphicDeviceDefinitionError error, but to no avail.
