Callgrind output does not include function calls - valgrind

Question

I have a simple .c program that makes a call to a function delcared and implemented in the same file.
I compile it using gcc:
gcc myProgram.c -o myProgram -g
Then I use valgrind with callgrind to generate the callgrind.out.* file.
valgrind --tool=callgrind myProgram
Then I use the call grind_annotate
callgrind_annotate callgrind.out.1974
But the result is something similar to what follows and it doesnt include the function call that is in the file. I tried different c code but I get similar results, any idea why?

Answer 1

Try to add these options to callgrind_annotate :
callgrind_annotate --threshold=100 --tree=both callgrind.out.*
--tree=both prints, for each functions, their callers and the called functions.
--threshold=100 will print all the events (default is 99% so now your function should be printed)
BTW, these two options can print a very important output, so you can run this command to find your function :
callgrind_annotate --threshold=100 --tree=both callgrind.out.* | grep your_function_name
EDIT 1
That's weird. Can you post your code ?
This is my code :
// myProgram.c
#include <stdio.h>
void foo(int value);
int main(void) {
foo(10);
return 0;
}
void foo(int value) {
printf("%d\n", value);
}
And this is my output :
$ gcc myProgram.c -o myProgram -g
$ valgrind --tool=callgrind ./myProgram
