I have just started looking at pyfort (see http://www-pcmdi.llnl.gov/software/cdat/index.html) to add Fortran extensions. Running pyfort produces a C file that contains an include: #include "Numeric/arrayobject.h" I have implemented Numeric Python, but nowhere can I find the above include file in the source. Any pointers would be appreciated. -- Fred Clare fred at ucar.edu
