[Numpy-discussion] Compiling for free on Windows32

I agree with Robert

There should be no reason on earth why you cannot use an Egg to package
Numpy. Setuptools is not fragile, it's very stable but requires a bit of
understanding.

The problem I have is not packaging numpy but compiling it on Windows.
If I could compile the C I'd have built the egg in moments. The fact
that I cannot compile the current version of Numpy is almost certainly
not the fault of setuptools!

Regarding the stability of Numpy in an Egg-wrapper - we run numpy 1.1.1
as an egg on about 100 workstations, 20 servers and countless grid CPUs
with no problems at all. It's exactly as stable as Numpy installed from
an exe, only we do not have to pay somebody to manually install it on
all those computers.

Nonsense. There is no reason that numpy *has* to be built with an
optimized BLAS. We try hard to ensure that. It is David's desire to
distribute numpy builds with optimized BLASes that does not fit into
eggs, not numpy. Plain numpy eggs are really straightforward.
