I have three files say

common_defs.h

main.c
#includes common_defs.h as well as common_defs.h
contains the main function

abc.c
#includes common_defs.h


i compile main.c and abs.c separately to creeate
the respective .o files
Now for the final compilation, my compiler (icc) gives multiple declaration error for all the constants defined in common_defs.h

Any solution,
