[Help-glpk] Problem Has no Primal Feasible Solution

[Daniele Micarelli]

Hi,
i'm attaching the two file  .mod and .dat to let you know

When i run these files with glpsol,  i get these two messages at the end:

Model has been successfully generated
and
PROBLEM HAS NO PRIMAL FEASIBLE SOLUTION

in my opinion should exist one solution

it's possible?
