[Cbc] Compiled cbc for ampl (ASL)

[shlomo bauer]

Hi,

I have yet to get cbc to work with ampl.

I am using the student version -- as reported by the -v option:

ampl -v

AMPL Student Version 20090611 (MS VC++ 6.0)

it works with lpsolve and other solvers.

Cbc on the other hand doesn't appear to work ampl.

I've compiled it with the ASL option --

any ideas?

Cbc appears to work ok with mps files.
