8. Утилита readelf

Вывести ELF заголовок программы с помощью утилиты readelf

readelf –h os2.o

9. Выводы

В ходе выполнения данной лабораторной работы мы научились автоматически собирать программу, написанную на С++, при помощи make-файла. Использовать отладчикgdb, а также использовать такие утилиты, какnm,objdump,readelf.
