Makefile not creating .o for a dependency

[Tidey]

Hello there,

I've been searching to see if I can find an issue to this problem but so far I haven't found anything that really helps.

I was making changes to one of the .h files of my project, nothing big simply commenting some unnecessary lines. When I tried running the makefile again, it updated all modules except for that one (security.h). I went ahead and added a 'clean' in efforts to force the makefile to make everything again.

Since then I've been getting the following error:

[Kalico@Kalico Modular_Prog]$ make
gcc -c main.c
gcc -c user.c
gcc -c menu.c
gcc -c security.h
gcc -o main main.o user.o menu.o security.o
gcc: error: security.o: No such file or directory
make: *** [main] Error 1
[Kalico@Kalico Modular_Prog]$

As the error says, security.o isn't created. In it's place I have security.gch.

I'm not certain why exactly it's causing this error, the first time I ran the makefile it compiled everything perfectly and I didn't change any lines, simply added the clean command.

# Makefile for the main application

main: main.o user.o menu.o security.o
        gcc -o main main.o user.o menu.o security.o

main.o: main.c user.h menu.h security.h
        gcc -c main.c

user.o: user.c user.h
        gcc -c user.c

menu.o: menu.c menu.h
        gcc -c menu.c

security.o: security.c security.h
        gcc -c security.h

clean:
        \rm *.o                                         
"makefile" 19L, 325C

Any insight is appreciated. Thanks!

This command in your makefile is not right
gcc -c security.h

You probably want

gcc -c security.c

Actually your entire makefile would be better off using the default rules like ....

# Makefile for the main application
main: user.o menu.o security.o

main.o: user.h menu.h security.h
user.o: user.h
menu.o: menu.h
security.o: security.h

clean:
	\rm *.o
