numarray on 64 bits
Did anybody use numarray on a 64 bits platform ? (e.g. SGI/Irix) The package works on our 64 bits platforms... using 32 bits mode, but not using 64 mode. Big crash in _ufunc... Is there a flag to set somewhere, trick, hint, noway ? -MP- ----------------------------------------------------------------------- Marc POINOT Alias: marcvs Email: poinot@onera.fr ONERA -MFE/DSNA/ELSA Tel: 01.46.73.42.84 Info: elsa-info@onera.fr 29, Div.

Numarray has been used on Compaq Alpha/Tru64 and also SGI Altix, but neither is an everyday platform for us at STScI.

This is probably a bug which has was created since we dropped Tru64 at STScI. A gdb traceback would be useful here to help understand where the crash occurred. Generally, crashes result from the improper use of ints/longs in the numarray C-code.

There's really only one flag that matters for 64-bit operation on UNIX: LP64. It's controlled/propagated in the file generate.py. LP64 asserts that longs and pointers are 64-bit, while ints remain 32-bit. I imagine you've already set this. Regards, Todd -- Todd Miller <jmiller@stsci.edu>
