GCC compiler error

Question

main: main.o print.o credits.o hello.o
        gcc -o main main.o print.o credits.o hello.o

main.o: main.c hello.h
        gcc -c -o main.o main.c

print.o: print.c hello.h
        gcc -c -o print.o print.c

credits.o: credits.c hello.h
        gcc -c -o credits.o credits.c

hello.o: hello.h
        gcc -c -o hello.o hello.h

I get this error when I use the make command

/usr/bin/ld:hello.o: file format not recognized; treating as linker script
/usr/bin/ld:hello.o:1: syntax error
collect2: error: ld returned 1 exit status
make: *** [main] Error 1

Answer 1

You should change the second last and last line -

hello.o: hello.h to hello.o: hello.c hello.h

gcc -c -o hello.o hello.h to gcc -c -o hello.o hello.c

The input here should be a c file.

For more understanding I would recommend you look at this link

Answer 2

I think the problem is that you are trying to compile a .h file,ie hello.h It should be hello.c that you should be compiling

main: main.o print.o credits.o hello.o
    gcc -o main main.o print.o credits.o hello.o

main.o: main.c hello.h
    gcc -c -o main.o main.c

print.o: print.c hello.h
    gcc -c -o print.o print.c

credits.o: credits.c hello.h
    gcc -c -o credits.o credits.c

hello.o: hello.c hello.h
    gcc -c -o hello.o hello.c

Should Work
