I am not quite sure what you mean by `interactive constraint solving'.
ECLiPSe is a programming language (rather than just a `constraint 
solver'), so you can write programs to do what you require.

If you mean some sort of real time interaction with the user, where the 
user can add constraints to the problem, then ECLiPSe does not provide 
any `ready-made' tools for you to enter constraints interactively, i.e. 
you need to program it to do so, and ECLiPSe itself may not be the best 
language to do this sort of GUI application. However, ECLiPSe does have 
interfaces to languages which are more suitable for this, like Java and

Some support is provided for monitoring violated constraints in 
libraries: lib(repair) and the newer lib(tentative). Note that these are
libraries and you need to write your own code (in ECLiPSe) to use them,
and are not `ready-made' tools.

Additionally, if you are using lib(eplex) [which interfaces to external
Mathematical Programming solvers], then in ECLiPSe 6.0, you can obtain 
the Minimal Conflict set for an infeasible problem if this is supported 
by the external solver (e.g. CPLEX).
