[f2py] Difficulties working on 64 bit windows platform.

[David Wainwright]

Hello,

I'm having difficulty building an f2py extension.
I have 64 bit Windows 7, running intel fortran (composerXE-2011) and am trying to create 64-bit modules to call from python.
I've attached a trace of my input command and the results below
It appears to be finding and using the fortran compiler correctly & building X64 modules,

However, when it tries to link, I get a fatal error indicating that the module machine type 'x64' conflicts with the target machine 'x86'.

It seems that the wrong linker may be being used, but I am unsure, there appears to be an alternative linker available in an /amd64 subdirectory.

Can anyone provide clues as to where I might look to fix this?

Many thanks,

David.
