All, I've decide that I'm going to tackle getting SciPy working on Mac OS X. So, my basic tasks are: 1. Patch Fortran compilation to support f2c. If I'm correct, I just have to modify build_flib.py to add the new class ? 2. Patch Other libraries as needed. So far I've found the following: In the Cephes module, I had to do the following: special/cephes/polmisc.c - replace malloc.h with stdlib.h special/cephes/polyn.c - replace malloc.h with stdlib.h Because malloc and free are defined in stdlib.h on OS X. 3. GIST won't compile so an alternate plotting library is necessary. I've been thinking of developing a plotting library on top of PyOpenGL. There are even some descriptions on getting postscript output (as a set of vector primitives) using the feedback buffer at: http://reality.sgi.com/mjk_asd/tips/Feedback.html Thoughts ? Suggestions ? Thanks, Tim Lahey
