[elephant-devel] Elephant on Windows/SBCL?

[Ian Eslick]

Elephant should work with Allegro on Win 32, it was my original  
development platform for Elephant, although I haven't tried it in some  
time.  An earlier version of Elephant worked on Lispworks/Windows  
although I think I recall some problems with the latest version of the  
unstable tree.

My impression from the last time I tried it was that SBCL was  
insufficiently mature on Win32 to be a reasonable configuration to  
target.  Has this changed?  Is it getting more use?

I would check UFFI support first - for running with BDB that's likely  
to be the hairy part.  Replacing the sb-posix calls for Windows  
shouldn't be too hard as Robert mentions.  Threads aren't needed for  
simple apps; I'm assuming you aren't going to be running this under a  
lisp web server which seems to be the most common use of Elephant.
