Has anybody been successful getting C integrators (Radau, Dopri) to work on OS X 10.8?
When I run one of the tests (dopri_event_test.py), the traceback indicates that the error originates with the method:
compileLib(self, libsources, libdirs)
included in Dopri_ODEsystem module. I'm assuming this has to do with the 64-bit incompatibility?
My scipy package was installed with Homebrew, rather than the recommended Fink. Is this the only explanation? And if so, why? I guess I'm reluctant to resort to Fink unless there are no other options. Has anybody overcome these issues?
I've been using PyDSTool on OS X 10.8, and also have trouble getting Radau or Dopri to work. The AUTO version (continuation of periodic orbits) of PyCont had some of the same issues, and I was able to modify that code so that it compiles on OS X 10.8. It was a nontrivial fix. I was thinking at some point of looking at the Radau and Dopri code to try something similar, I just haven't gotten around to it. It's on my list!
What modifications did you make to PyCont to get it working on OS X 10.8? Any luck with Radau or Dopri?
Unfortunately, event detection is prohibitively slow with the scipy VODE integrator. The C integrators use a much more efficient algorithm for event detection, one based on interpolation rather than time-step refinement.
