No such file or directory, confused??

[Brandon77]

I have the following makefile that should compile a list of source files into an executable. When trying to make, I get the error shown. I can't understand why I am getting it since all the source files exist and are in the same directory. Any ideas?

Makefile:

SOURCE_DIR = $(top_srcdir)
SOURCE_INCLUDE_DIR = $(SOURCE_DIR)/../../include
SOURCE_COMMON_DIR = $(SOURCE_DIR)/
SOURCE_LDSCRIPT_DIR = $(SOURCE_DIR)

BUILD_DIR = $(top_builddir)
BUILD_PROM_DIR = $(BUILD_DIR)


CC=gcc
CFLAGS=-c -Wall
LDFLAGS=-M -T $(SOURCE_LDSCRIPT_DIR)/Linker.ld  
SOURCES= Main.c \
         ErrorHandler.c \
         ScriptProcess.c \
         Queues.c \
         Commands.c \
         Processes.c \
	 Utilities.c \
     	 Executive.s \
	 time.o \
         $(SOURCE_COMMON_DIR)/Esr.c \
	 $(SOURCE_COMMON_DIR)/bitset.s

OBJECTS=$(SOURCES:.c=.o)
EXECUTABLE=Program1

all: $(SOURCES) $(EXECUTABLE)
	
$(EXECUTABLE): $(OBJECTS) 
	$(CC) $(LDFLAGS) $(OBJECTS) -o $@

.c.o:
	$(CC) $(CFLAGS) $< -o $@
.s.o:
	$(CC) $(CFLAGS) $< -o $@

Error:

Fixed for now by adding absolute path to files in directory. Seems like it shouldn't matter, but I'm not getting the error anymore
