Hi Sergii,

Unfortunately we had a sudden and unexpected change to the machines we 
build ECLiPSe on, and we are in the process of migrating to new 
machines, but there are some difficulties, and it is unlikely we will be 
able to produce new distributions in the next few days.

John Forrest (the main implementer of the CBC and CLP solvers) have 
kindly updated CBC with the changes so that those messages are no longer 
sent directly to stdout. I had wanted to update the CBC in our binary 
ECLiPSe distributions, but this will need to wait till we restart our 
daily builds.

The CBC/CLP solvers are third-party solvers and not part of ECLiPSe; 
these solvers are distributed with our binary distributions for 
convenience and because their license allow us to do so. Eplex can also 
interface to other MP solvers, and your examples should run regardless 
of the actual MP solver used.

Cheers,

Kish
