Do you mean that your problem has more than two billions coefficients?
Or you just need to use long int's due to some other reasons? If the
former, it is doubtful that glpk is able to solve such huge problem.

Using 64-bit mode is only reasonable to address more space than 4Gb
on solving large instances. To compile glpk in 64-bit mode you should
specify appropriate hardware model options; for details see:
