Hi, I had a mini-vacation and I spent a while trying to get sage working with VTK on a Macbook. The machine is somewhat slow and experimenting takes a long while. I've managed to get VTK built with Sage but required a framework build. Here are the details.
I've been using sage-3.4 (since thats what I had with me). I have a fresh sage (3.4) install where I installed cmake from Jaap's package here: http://sage.math.washington.edu/home/jsp/SPKGS/MayaviOSMesa/ I then got http://sage.math.washington.edu/home/jsp/SPKGS/MayaviOSMesa/vtk-cvs-20090316osmesa.spkg and changed the spkg-install so it builds on the Mac. I first tried building VTK with the existing sage python build but kept running into build errors with VTK unable to find several Python symbols. I configured VTK to build with the libpython2.5.a but that failed to build with link errors that I forgot to note down (I must have tried 10 different things trying to get this going). After various failed attempts I finally decided to change the way sage builds its Python and added: --enable-framework="$SAGE_LOCAL/Frameworks" to the configure command in the spkg-install of python-2.5.2.p9 that ships with sage-3.4. This built successfully. I basically untarred the standard spkg, changed the spkg-install suitably and ran it within a sage -sh session. I then built VTK with the following configuration for cmake: -DPYTHON_EXECUTABLE:FILEPATH=$SAGE_LOCAL/Frameworks/Python.framework/Versions/2.5/bin/python\ -DPYTHON_INCLUDE_PATH:PATH=$SAGE_LOCAL/Frameworks/Python.framework/Headers\ -DPYTHON_LIBRARY:FILEPATH=$SAGE_LOCAL/Frameworks/Python.framework/Versions/2.5/Python\ -DVTK_USE_CARBON:BOOL=ON This built VTK perfectly. I initially ran into problems like so: sage: import vtk Fatal Python error: Interpreter not initialized (version mismatch?) $SAGE_LOCAL/bin/sage-sage: line 205: 1407 Abort trap sage-ipython "$@" -i But figured that my existing builds were confusing matters and once I moved that old build out of the way, everything worked great. I was able to do this: sage: import vtk sage: c = vtk.vtkConeSource() [...] I have the following questions: 1. Why isn't --enable-framework turned on by default for the sage python build on the Mac? If this isn't a hassle can you please consider making this the default? 2. What else would it take to get the VTK package to optional quality? Thanks! cheers, prabhu --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
