One of the things I am confused about is how to link to numpy on a windows NT. In the docs, it basically just says to include objectarray.h. But, I assume I must also include a static lib or a DLL. I also assume that the pyd files are just dlls under windows. Since they don't have the dll extension, I must manually load them. Is this correct? I just plan to export a 2D array via PyArray_FromDimsAndData. The let a user run a python script and wait for it to finish. -- Cheers, Karl Bellve ICQ # 13956200 Biomedical Imaging Group TLCA# 7938 University of Massachusetts Email: Karl.Bellve@umassmed.edu Phone: (508) 856-6514 Fax: (508) 856-1840 PGP Public key: finger kdb@molmed.umassmed.edu
