Ah yes, forgot about mayavi. The problem with more recent versions of vtk is that in python "import vtk" does not work, because of linking problems of the python modules. There are several different ways of resolving the python-supplied symbols in python modules, and so far I have not had success with any of them. This is a very time-consuming process, not only because vtk takes a long time to compile, but mainly because of the cmake build system, which is a royal PITA in this situation. Trying to convince it to use a certain linker flag and to link or not to link to a certain library is a major hacking challenge. If anyone on the list wants to give it a try, I'd be happy. The possibilities are: 1. Let cmake do what it wants (after setting a lot of cmake flags, of course). This resolves undefined symbols from libpython2.5.dylib and links the modules with that dylib. For many python modules (and this happens with vtk52 and vtk54, but strangely not with vtk50), this situation leads to the famous "interpreter version mismatch" crash when the module is imported into python. I think this problem might disappear with python2.6, but I haven't had time to check. 2. Add the "-bundle_loader /sw/bin/python2.5" linker flag. This uses the python executable to resolve symbols. It is the recommended method for linking python modules, but most of the time leads to linker errors. 3. Try to get rid of libpython.dylib on the linker line and add either "-undefined dynamic_lookup" or "-flat_namespace -undefined suppress". This works for many python modules, but with vtk I got linker errors, too. I'll continue trying this, but I cannot estimate when I will succeed. In any case, I will never try to fix anything that involves funny java compiler errors. -- Martin ------------------------------------------------------------------------------ Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev _______________________________________________ Fink-devel mailing list Fink-devel@lists.sourceforge.net http://news.gmane.org/gmane.os.apple.fink.devel Subscription management: https://lists.sourceforge.net/lists/listinfo/fink-devel
