Question

C language. A Makefile should have (at least) the following rules:
Rules to compile .c files into .o files (input.o, display.o, and main.o)
An all rule that will combine input.o, display.o, and main.o into an executable called "scroll".
A clean rule that will remove the executable scroll and all .o files
A run rule that will run the program.
Any extra rules you find helpful.

Solution:

I dont have any information about the input.c,display.c and main.c files so i am using my own simple coded files. But the makefile works with your files also...

Look at the code and comments for better understanding...................:-))

Screenshot of the codes:

-/QA/c/input.c - Sublime Text (UNREGISTI -/QA/c/display.c - Sublime Text (UNREGISTERE Find View Goto Tools Project Pref File Edit -/QA/c/main.c - Sublime Text (UNREGISTERED) Selection Find View Goto Tools Project Preferences Help File Edit Selection Find View Goto Tools Project File Edit Selection input.c main.c int main() #include<stdio.h> void fi() 2 display.c #include<stdio.h> void f2() { printf("From display.c\n"); { { 1 2 3 4 5 3 4 5 6 1 2 3 4 5 f10; f2(); printf("From input.c\n"); } } } Line 1, Column 1 Tab Size: Line 1, Column 18 Tab Size: 4 Line 1, Column 11 Tab Size: 4 C

Screenshot of the Makefile code:

--/QA/c/Makefile. - Sublime Text (UNREGISTERED) Project Preferences Help File Edit Selection Find View Goto Tools Makefile all: compile run #Rules to compile the input.c display.c and main.c input.o: input.c gCC -c input.c display.o: display.c gcc -c display.c #I am passing -W option to disable unwanted warnings you can remove it if you want main.o: main.c gCC -C-W main.c 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | #Rule to generate the executable scroll compile: input.o display.o main.o gcc input.o display.o main.o -o scroll #Rule to run the executable run: ./scroll #Rule to clean the file clean: rm -rf *.0 U Line 10, Column 1 Tab Size: 4 Makefile

Output:

gm@Tricia: -/QA/C File Edit View Search Terminal Help gm@Tricia:-/QA/c$ make gcc input.o display.o main.o -o scroll ./scroll From input.c From display.c gm@Tricia:-/QA/c$

Code to copy:

all: compile run
#Rules to compile the input.c display.c amd main.c
input.o: input.c
        gcc -c input.c
display.o: display.c
        gcc -c display.c
#I am passing -w option to disable unwanted warnings you can remove it if you want
main.o: main.c
        gcc -c -w main.c

#Rule to generate the executable scroll
compile: input.o display.o main.o
        gcc input.o display.o main.o -o scroll
#Rule to run the executable
run:
        ./scroll
#Rule to clean the file
clean:
        rm -rf *.o

I hope this would help.................:-))
