Question

I am new to makefiles and I am a bit stuck. I have two c source files called trade.c and report.c . They both depend on a file called acc.h. The acc.h file is composed of two other header files, users.h and resellers.h. I am wondering how you write the dependency of the two header files to the acc.h file. I have so far…

OBJECTS = trade.c report.c
CC = gcc

trading: $(OBJECTS)
        $(CC) $(OBJECTS) -o trading

trade.o: trade.c accts.h
        $(CC) -c trade.c

report.o: report.c accts.h
        $(CC) -c report.c

Any help is greatly appreciated.

Answer 1

You have no other choice than to add all the header files in the dependency list for the object file, as follows.

trade.o: trade.c accts.h users.h resellers.h
        $(CC) -c trade.c
