I tried to solve the problem using the option --nopresol but I obtained the 
same result....
I send you the solution output  file. What's the meaning of  "Status:INTEGER 
UNDEFINED" ?

Try using the option `--nopresol' to disable the lp presolver.
If no fasible solution will be found, most probably, your lp is really
infeasible, in which case you can obtain additional information from
the solution output sheet.
