C 基础 - GDB调式工具

 

安装

brew install gdb 

 

一、单步执行和跟踪函数调用

/* main.c -- 学习gdb调试工具 */
#include <stdio.h>

int add_range(int low, int high)
{
    int i, sum;
    for (i = low; i <= high; i++)
        sum = sum + i;
    return sum;
}

int main(void)
{
    int result[100];
    result[0] = add_range(1, 10);
    result[1] = add_range(1, 100);
    printf("result[0]=%d\nresult[1]=%d\n", result[0], result[1]);
    return 0;
}

 

 

第一步：使用-g生成目标文件

gcc -g main.c -o main
