Linking m5ops.h to a C project

I have a C application that is using a function from the Gem5 operations called "m5_dumpreset_stats()".

So, I did the following, I included the header file of this function:

#include "../gem5-stable/util/m5/m5op.h"

then in my source file I called the function:

void foo()
{
   m5_dumpreset_stats(0,0);
   /* For loop */
   m5_dumpreset_stats(0,0);
}

To build my project I'm using a Makefile : 

CC=arm-linux-gnueabi-gcc
CFLAGS=-g -c -Wall -O3 -mfpu=neon
LDFLAGS=-static

SOURCES=$ foo.c
OBJECTS=$(SOURCES:.c=.o)

EXECUTABLE=foo

all: $(TASKMAP) $(SOURCES) $(EXECUTABLE)

$(EXECUTABLE): $(OBJECTS) 
$(CC) $(LDFLAGS) $(OBJECTS) -lm -o $@

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

 clean: 
    rm -fr $(OBJECTS) $(EXECUTABLE)

My first guess is that I have to link the library using the Makefile but honestly, I don't know how? Could someone show me the right way to do it?

P.S : m5_dumpreset_stats(delay,period): Save and reset simulation statistics to a file in delay nanoseconds; repeat this every period nanoseconds.

Solution

  • Thank you for your contributions. This was my solution: See that I'm using ARM core for simulation I used Makefile.arm to generate a library called "m5" then I had to do following changes in my own Makefile:

    $(EXECUTABLE): $(OBJECTS) 
 $(CC) $(LDFLAGS) $(OBJECTS) -lm -L"/home/anoir/gem5-stable/util/m5" -lm5 -o $@

    and I kept the inclusion in my header file to call m5op.h like this:

      #include "/home/anoir/gem5-stable/util/m5/m5op.h"

    Finally, I've tested it in the simulator and checked the stats file and Works perfectly Thanks to you.
