[Coin-discuss] Re: Turn off all output by default in bcp (Paul Pacheco)

[John J Forrest]

I don't know enough about bcp to explain why Clp0000 message is happening. 
 It does not when using CBC and setting logLevel 0 should have done it. If 
you are using ClpSimplex to read mps file then that should work as well. 
If using CoinMpsIO directly then you can set logLevel there as well.  If 
you use the stand-alone version of clp you can check that this is possible 
e.g.

clp -loglevel 0 -import ../Mps/Netlib/25fv47.mps -duals -loglevel 1 
-primals 

switches output off until last bit.

This is generated in CoinMpsIO.cpp, I believe. I don't know of an easy way
to disable it. You can modify your copy of the code to disable it.

Comment out line 65 of BB_tm.cpp

This is an irritating message from Clp, I agree. If someone could tell
me how to disable it, I would be happy too. I am able to disable
some of these by using:

   OsiClpSolverInterface * clp = new OsiClpSolverInterface;
   clp->messageHandler()->setLogLevel(0);

in BB_lp::initialize_solver_interface(). I believe that this should be
disabled if log level is zero, but it is not always so.

Set BCP_TmVerb_FinalStatistics 0
