[Coin-ipopt] ASL error message: "solver cannot handle CLP extensions" ?

[Andreas Waechter]

Hi David,

I think this messages means, that Ipopt cannot handle "Constraint Logic 
Programming" constraints.

This message shows up when you forget to have a "=", "<=", or ">=" for a 
constraint in your AMPL model.

I hope this helps,

Andreas
