Hi, I just updated my coin-Cbc copy from /svn/Cbc/trunk. The command make end up with the following error : .../coin-Cbc/CoinUtils/src/CoinFinite.hpp:80: error DBL_MAX undeclared first .... Thanks for help. Cheers, Hacene Hacene Ouzia Ph.D student Laboratoire d'Informatique de Paris 6. hacene.ouzia at lip6.fr
