I though I'd mention this to see if anyone else had this problem:
When I first tried to make the Numeric,
make Makefile -f Makefile.pre.in
sent my machine into infinite loop.
I mucked around a bit and got it to work. However, when I tried to
recreate it I got stumped. Once I unpacked it fresh and it looped
again. When I copied the Makefile.pre.in from the working version of
NumPy over, it worked.
"AH HA! I just need to dof a diff and I'll know the problem." So I
did a diff against the original and there was NO DIFFERENCE. So I
unpacked NumPy again into another directory and this time it worked.
And it worked several more times. So now I'm stumped.
Did anyone else see this?
On a different note: zeros is sort of uninformative if you give it a
number instead of a tuple (an easy mistake...).
>>>* from Numeric import *
*>>>* zeros(5)
*Traceback (innermost last):
File "<stdin>", line 1, in ?
AttributeError: __len__
>>>* zeros((5))
*Traceback (innermost last):
File "<stdin>", line 1, in ?
AttributeError: __len__
>>>* zeros((5,))
*0 0 0 0 0
