For the following make file copied below, I am getting the missing separator error. Nothing seems to be wrong with the tabspace.

OBJS = driver.o snapshot.o
SHOBJS = malloc.o mymemory.o
CC = g++
DEBUG = -g
CFLAGS = -Wall -c $(DEBUG)
LFLAGS = -Wall $(DEBUG)
Snapshot: $(OBJS)
  $(CC) $(LFLAGS) $(OBJS) -o Snapshot
driver.o: snapshot.h driver.cpp
  $(CC) $(CFLAGS) driver.cpp
snapshot.o: mymemory.h snapshot.h snapshot.cpp
  $(CC) $(CFLAGS) snapshot.cpp
libmymemory.so: $(SHOBJS)
  gcc -shared -o libmymemory.so malloc.o mymemory.o
malloc.o: malloc.c
  gcc -fPIC -g -c -Wall malloc.c
mymemory.o: mymemory.cpp
 gcc -fPIC -g -c -Wall mymemory.cpp 
clean:
 \rm *.o *~ Snapshot

Answer

Line 18 is gcc -fPIC -g -c -Wall mymemory.cpp. Make is expecting a separator, typically :. It's not detecting this line as a command. You mistyped the intendation: you have spaces where you should have a tab.

Good editors highlight makefile lines that begin with spaces but look like they should begin with a tab instead.
