[Couenne] cannot get .sol file

[Zeynep Erkin]

Hello.

I'm new to Couenne and having trouble with getting the .sol file. I believe
my installation has no problem as 'make unitTests' work fine. When I solve
a small problem, which is attached, on command line with 'couenne
example2.nl', I get the following message:

.......:bin ......$ couenne example2.nl

Couenne 0.5.5 -- an Open-Source solver for Mixed Integer Nonlinear
Optimization

Mailing list: couenne at list.coin-or.org

Instructions: http://www.coin-or.org/Couenne
couenne: jacdim: got M = 0, N = 0, NO = 0

Does this mean that there is a problem with the format of example2.nl - no
columns, no rows? When I feed the same problem to the NEOS server (
http://www.neos-server.org/neos/solvers/minco:Couenne/AMPL.html) I'm able
to get an output. Could you please help?

Thanks,

Zeynep
