Re: [eclipse-clp-users] Gecode and Gurobi

Hi Giuseppe,

Gecode (currently 4.4.0) is fully included with ECLiPSe.

However, we cannot distribute Gurobi, which is a commercial solver.
Our if_gurobi50.tgz package only contains the interface layer,
so you have to obtain libgurobi50.so from Gurobi directly.


Regards,
Joachim
