How Can I fix 'Makefile:6: *** missing separator. Stop'.?

Question

all: elfparser

elfparser: disasm.o elf-parser.o elf-parser-main.o elf-program_read.o srec.o
    gcc -o elfparser disasm.o elf-parser.o elf-parser-main.o elf-program_read.o srec.o

elf-parser-main.o: elf-parser-main.c
    gcc -c -o elf-parser-main.o elf-parser-main.c

disasm.o: disasm.c
    gcc -c -o disasm.c

elf-parser.o: elf-parser.c
    gcc -c -o elf-parser.c

elf-program_read.o: elf-program_read.c
    gcc -c -o elf-program_read.c
    
srec.o: srec.c
    gcc -c -o srec.c

clean:
    rm -rf *o elfparser

Answer 1

This question is already VERY NICELY although slightly differently answered here

Here is a slightly better approach:

BIN=elfparser
SRC=disasm.c elf-parser.c elf-parser-main.c elf-program_read.c srec.c

# OBJ filenames are created from SRC filenames by replacing .c with .o
OBJ=$(SRC:%.c=%.o)

CC=gcc
CFLAGS=-O2 -g

default: $(BIN)

# To create the binary, build all objects first
$(BIN): $(OBJ)
        $(CC) -o $@ $(OBJ) 

# How to generate a .o from a .c rule:
%.o: %.c
        $(CC) $(CFLAGS) $(INCLUDES) -o $@ -c %< 

If you decide to cut and paste this code remember that the lines that are under the rules (i.e. commands that run in the shell to do the work) HAVE TO HAVE A <TAB> (not spaces) before them.
