Thanks for the tips! They were very helpful, and I'm getting there.
I still have some questions:
1. I uninstalled Python 2.4 and installed Python 2.3, figuring that
SciPy binaries built against Python 2.3 would be upwardly compatible,
but perhaps not vice versa. Is this true? I noticed you built
separate binaries for NumPy for Python 2.3 and 2.4 on Windows but
just one set on Linux -- why?
2. I've been getting various LAPACK errors since I moved away my
custom-rolled ATLAS/LAPACK libraries, but things are looking better
now. I presume that the Linux binaries should be built without an
ATLAS dependency? If I link against /ed's/own/atlas/library.so, the
binaries will be useless to anyone but me, right? ...
It makes me wonder if we need Linux binaries at all. I've noticed
that numarray only distributes Windows binaries, probably since the
source tarball is generally far more useful, and because Linux
distributors will soon package SciPy themselves anyway. Could we do
3. Are there any Windows linking traps to be aware of? I presume we
link SciPy against an ATLAS DLL that gets rolled up into the .exe
Just out of interest, it seems Mandrake 10 ships with an incomplete
LAPACK (4.3 MB, rather than Debian's 5.3 MB), with various missing
symbols. Why do they *do* this?! And the NumPy / SciPy setup
scripts are really very smart -- good job, guys! Witness this:
libraries = ['f77blas', 'cblas', 'atlas']
library_dirs = ['/home/schofield/Tools/lib/atlas_moved_away']
language = c
