Linux下使用addr2line来定位进程崩溃

废话不讲。

测试代码：

main_entry.c

#include <stdio.h>
#include "mylib.h"

int main(void)
{
    test_funcA();
    return 0;
}

mylib.h

#ifndef MY_LIB_H
#define MY_LIB_H


void test_funcA(void);

#endif // MY_LIB_H

mylib.c

#include <stdio.h>
#include "mylib.h"


void test_funcA(void)
{
    printf("Init  test_funcA called\r\n");

    int *pX = 0;
    *pX = 100;

    printf("test_funcA called\r\n");
}
