[Couenne] Couenne and Cplex

[Giacomo Nannicini]

Hi,
if I set the option:

couenne.lp_solver cplex

and try to use Cplex as LP solver, I get a huge amount of error messages:

CPX0000  CPLEX Error  1217: No solution exists.

I didn't look into the problem, but maybe somebody knows what is the
cause of this problem and save me some time? Is this just a
visualization issue, i.e. the LPs are actually correctly solved and
simply turning off the output on screen is the right thing to do?

Thanks

Giacomo
