Re: [eclipse-clp-users] 'Problem is infeasible!' in eplex goes to stdout

Hi Sergii,

I am actually in the middle of building the new Cbc binaries, which I 
have verified does resolve your issue.

Sorry this is taking so long. It took us a while to get our daily build 
system working again, and then I was away earlier this month.

Hopefully the Cbc binaries will be built and installed later today or 
tomorrow, and then our next ECLiPSe build will use these new Cbc binaries.

Cheers,

Kish
