I have read a similar question here: Valgrind not showing line numbers in spite of -g flag (on Ubuntu 11.10/VirtualBox)
However, the solution does not solve my problem. See the output of valgrind below. It does not tell me the line number in my main function.
My software versions: gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) Valgrind-3.10.0.SVN
Here is the source code:
#include<stdio.h>
/* warining: this program is wrong on purpose. */
int main(){
int age = 10;
int height;
printf("I am %d years old.\n");
printf("I am %d inches tall.\n", height);
return 0;
}
Makefile:
CFLAGS = -Wall -g -static
src = ex4.c
all: $(src)
cc -o ex4 $(src)
clean:
rm -f ex4
Valgrind command:
$valgrind --track-origins=yes ./ex4
Valgrind output:
