[Advcomparch] Πρόβλημα κατα την εκτέλεση του sniper

[Κωνσταντινος Πανιδης]

Ακολούθησα βήμα βήμα την διαδικασία της εκφώνησης  σε VM ubuntu 18.04,   gcc
7.5.0   και όταν τρέχω την εντολή    :

./run-sniper -c gainestown -d sim_output
--pinballs=/home/ntinos/comparch/sniper-7.3/cpu2006_pinballs/gcc/pinball_short.pp/pinball_t0r1_warmup3000_prolog0_region1000000002_epilog0_001_1-00000.0.address

λαμβάνω έξοδο:
