Witam,
Posiadam projekt od kolegi z forum, któremu wszystko się ładnie kompiluje, a ja po dodaniu go do eclipsa i próbie kompilacji otrzymuje taki błąd:

pliki common.c


oraz common.h

Witam
wygląda na to ,że nie masz zdefiniowanej zmiennej

ram_cfg

Domyślam się tylko ,że powinna ona być gdzieś w pliku w którym
definiujesz zmienną

eem_cfg i pgm_cfg

Używasz wskaźnika na coś co się nazywa ram_cfg
a coś takiego nie jest w Twoim programie zdefiniowane.
W comm.h masz tylko coś takiego:

No i tego pliku w którym to extern jest zdefiniowane brak
