Can you clarify the people you think will get stuck? I think I'm right in saying that anyone with a C extension should be able to build them against numpy, by installing the free (as-in-beer) MS tools? So do you just mean people needing a Fortran compiler? That's a small constituency, I think.
Off the top of my head there's SciPy and pymc...
Anyway, I'm butting in because I wish this discussion could separate between the user perspective and the developer perspective.
FWIW,
1) From a user's perspective, I don't understand this either. If you are already using a closed source, not-free-as-in-beer operating system, why would you not use (or buy!) a closed source, not-free-as-in-beer Fortran compiler?
Indeed. Though I really have no clue on the Windows use cases. Maybe most Windows users don't want to compile anything, just use numpy and scipy from Python?
Well - yes - as a packager I really want to be able to provide a binary so my binary consumers don't have to have a C compiler installed. I imagine it's the same for all of us packagers out there.
2) BUT, the argument I've seen that I can at least understand is that the release manager should be able to do a release using only open source tools (even using Wine instead of Windows) and not rely on a limited number of licenses. And that the release manager must be able to perform all the official builds directly.
As the release manager, I really only have two requirements:
* I want to ssh in there from my Ubuntu * I want to automate the whole process
For Mac, linux and Wine I can do that. So I have just spend few hours browsing the net and it looks like that the combination of Windows PowerShell 2.0:
http://en.wikipedia.org/wiki/Windows_PowerShell
and some SSH server, there are quite a few, one commercial but free for one user one connection (perfect for me!):
http://www.powershellinside.com/powershell/ssh/
So if I understand the pages correctly, I can login there from linux, and then I use the PowerShell commands to script anything. It looks like I can even use my Fabric fabfiles with powershell:
https://gist.github.com/diyan/2850866
I can also use git with PowerShell:
http://windows.github.com/ http://haacked.com/archive/2011/12/13/better-git-with-powershell.aspx
So the final problem is how to execute MSVC and Fortran from Power Shell on Windows. These links might help for MSVC:
http://stackoverflow.com/questions/4398136/use-powershell-for-visual-studio-... http://geekswithblogs.net/dwdii/archive/2011/05/20/automating-a-visual-studi...
Finally, for Intel Fortran + powershell:
http://software.intel.com/en-us/forums/topic/284425
So I think it is all possible. If somebody can provide a machine with Windows, MSVC, PowerShell2.0, SSH server and some Fortran compiler, it should be possible for me to automate everything from Ubuntu using my Fabric files (https://github.com/certik/numpy-vendor).
Many many thanks for trying to solve this. I had really started to give up hope. I think you will need a developer's license for MKL for Numpy. Ralf - any ETA for those? I think I'm right in thinking you'll need a Fortran compiler for Scipy but not Numpy? Can we defer the Scipy build until after the Numpy build? I will try to get you set up with ssh on my Windows 7 machine in case you can use it. It has the MS tools. Thanks again, Matthew
