Yes, it does, I think I tried it. But this mean duplicating dll, and 
more worrying, filesystem manipulations, which I don't like much 
(windows having this extremely annoying 'feature' of locking files by 
default, which is another thing I would have to care about).

I agree, but once you've said modifying PATH and system32 are not the 
right way, and there is no other way to do it, what's your conclusion :)

The first solution may indeed work (perhaps in C:\Python2x\Lib as well ?)
but the second does not. I tried it several times (same with Linux BTW), the
library search is then the default one, not Python's one.

Well, I don't see that happening unintentionally. Installed modules have 
a directory architecture, so this is not much of an issue, or am I 
missing something ?

Have you tried installing the DLLs to C:\Python2x or to the same
directory as the numpy .pyd? As far as I know, this should work.

Obviously there are some issues: multiple modules might be linked to
MKL, in which case you would be duplicating a lot of files, but hey,
so it goes. Ideally, all the modules should be using one module to
interact with native BLAS and LAPACK.

In my opinion, modifying the PATH or installing to System32 are not
ways to properly deploy DLLs on Windows.

It is exactly the same problem, yes. Right now, my installer does not 
modify the environment at all (like MKL or ACML, actually), and you have 
to do it manually (add PATH, or put in system32).

numpy 'dll' (they are technically dll, but are named .pyd on recent 
version of windows) are mandatory, and is not a problem: it is handled 
by python (whose import mechanism knows how to import dll not in the 
path env var).

Well, neither ACML or MKL does it, at least the versions I looked into. 
You have to launch a special cmd.exe (like for VS2005) which import the 
variables.

Now that you provide an installer for Atlas, it may become the same problem
as MKL, can't it ?

Yes, they will complain to you for sure, but I can't see where dynamic
libraries can become a problem :
- are they numpy dlls ? is so there is a problem, I agree with you
- are they external dlls ? If so, the installer must have set up everything
so that everything works, but this is where people bark at the wrong people
: the users of the dll and not the installers.

You seem to indicate that the problem is the last dlls, am I correct ?

Atlas is not a problem, because if you know how to build a dll for 
ATLAS, you know how to handle environment variable problems. It is not a 
purely technical problem, but a combination of both cultural and 
technical. I know that if I tell you, Matthieu, to put you library path 
in your path, you won't tell me it does not work if the PATH is changed 
or something similar. But that's not how most windows users work in my 
experience.

As for the problem: if you use PATH for dll, you need:
- to use PATH inside scons, that is polluting the build environment 
with a variable you cannot control at all.
- to add the path of the used libraries into the user environment.
I can imagine many things going wrong in this scenario. And guess who a 
user will complain to if something is messed up ? :)

Yes, it is a problem, at least it is advertised as such on mkl release 
notes (static vs dll). I could use PATH and get away with it, but I am 
reluctant to do that, because it is really fragile. If I could be sure 
that nobody would complain about it when it does not work, then I would 
do it in a minute (codewise, it is trivial; actually, the development 
version of numscons does it, because it is useful for debugging).

But by experience with all my other packages, windows installation is 
always  what get me the most emails, because windows is more fragile, 
and its users less aware of technical issues. I am okay spending time on 
code, much less spending time on a platform which I do not use, on a 
project which I am working for free. So it really boils down to either 
someone pays me to do it, or someone tells me how to do it reliably (I 
would of course do something which works reliably, if anyone can explain 
to me how to).

If you use an installed ATLAS/MKL/... library, I don't know where is the
problem wit linking with them :|

Good stuff. I noticed that the Launchpad page says:

"I decided not to support dynamic linking against 3rd party dll.
Because of intrinsics windows limitations, it is impossible to do it
in a reliable way without putting too much burden on the maintainer."

I might note that I had problems with NumPy and other C code crashing
randomly when statically linked against MKL 9.1 on Win32 (probably
when using multiple cores). Dynamically linking fixed the problem. I
haven't tested with MKL 10 yet.

[Numpy-discussion] [ANN] numscons 0.4.1. Building numpy with MS compiler + g77 works !

2008-02-18 Thread David Cournapeau
Hi,

I've just finished a new release of numscons. This version is the
first one to be able to compile numpy using MS compilers and g77
compiler on windows, which was the last "big" platform not supported
by numscons.

This also means I can now refocus on building scipy with numscons, so
that the whole numpy/scipy framework can be built with numscons on all
platforms. This release is available through pypi (just use
easy_install numscons, or easy_install -U numscons to upgrade a
previous install), as well as on launchpad:

https://launchpad.net/numpy.scons.support/0.4/0.4.1
