Я должен отредактировать сложный код, написанный на Фортране. На самом деле, у меня нет хороших знаний о Фортране. Поэтому в этом посте я надеюсь получить вашу помощь.
В этом коде кто-то объявляет переменные по заголовку file-commonkb.h:
common/cntrl2/SWNU,BB6(500,500)
real*8 SWNU,BB6
при запуске:
valgrind --tool=memcheck --leak-check=full --log-file=log ./main
У меня ошибка:

Как я могу решить эту проблему?
