Hi all, I have received a report that the Fortran kD tree does not build correctly on Mac OS X 10.8. For Brian Crosby, when he runs: from yt.utilities.kdtree import fKD he gets: ImportError: dlopen(/Users/crosby/yt-x86_64/lib/python2.7/site-packages/yt-2.5dev-py2.7-macosx-10.4-x86_64.egg/yt/utilities/kdtree/fKDpy.so, 2): Symbol not found: _fkdgetpointerchunk_tags_ Referenced from: /Users/crosby/yt-x86_64/lib/python2.7/site-packages/yt-2.5dev-py2.7-macosx-10.4-x86_64.egg/yt/utilities/kdtree/fKDpy.so Expected in: flat namespace I'm wondering if any other users of 10.8 can run the import command above, and tell me what you get? I'd like to narrow this down to Brian's 10.8, or 10.8 in general. If you get an error like "ImportError: No module named fKD", I'd like you to please try the following: - Make sure you have Forthon installed. Try "Forthon" from the command line, if it prints some stuff, you're set. If not, you can get it here http://hifweb.lbl.gov/Forthon/ - Go to your yt install directory, and navigate to the src/yt-hg/yt/utilities/kdtree directory. In there, please type "make". - Navigate up three levels (cd ../../..) and type "python setup.py install" with this done, please try the first import command above again, and if you get an interesting error message, please send it back.
