The fact that the wrapper for python worked as it was occurred to me after I hit the send button. How does the loader work on BSD? Does it expect libraries to be in certain standard places? Perhaps Chuck ended up with the ifeffit library in some non-standard place and so needs to fix that, set an environment variable (like on SGI), or fix the loader configuration (like on linux). Anyway, I am glad to hear that such good progress is being made. I wish I could contribute more to the immediate problem. Do post the screen messages from the build, as Matt suggested. I mostly grok perl's strange and numerous messages (which must say something bad about me .... ;-) I wanted to mention that this week I made some good progress on Artemis (I had all of Monday at home watching a contractor poke holes in my walls!) There are still alot of clunky interface problems, but Artemis will run to completion a fit with one data set using any number of feff calculations and it will plot the results in a manner that rsembles Athena. That is, you can select the data, the fit, and/or any number of paths from the list in the skinny panel on the right and click a button for plotting in k, R, or q. Model building needs a lot of work, but its usable. I would love if the Mac effort could succeed soon -- that would somewhat increase the number of alpha testers ;-) B -- Bruce Ravel ----------------------------------- ravel@phys.washington.edu U.S. Naval Research Laboratory, Code 6134 phone: (1) 202 767 5947 Washington DC 20375, USA fax: (1) 202 767 1697 NRL Synchrotron Radiation Consortium (NRL-SRC) Beamlines X11a, X11b, X23b, X24c, U4b National Synchrotron Light Source Brookhaven National Laboratory, Upton, NY 11973 My homepage: http://feff.phys.washington.edu/~ravel EXAFS software: http://feff.phys.washington.edu/~ravel/software/exafs/
