When I use glpsol to solve my model (written in MathProg, with separate

am referring to a "dummy" input I use to verify the correctness of my

get the following message:

Model has been successfully generated
*glp_mpl_build_prob: row obje; constant term 84384 ignored*

Perhaps preprocessing introduces the constant term.
