windows,linux下eclipse搭建环境配合gdbserver调试应用环境

linux下的配置

Ubuntu 9.10,
Eclipse ---Version: 3.5.1 Build id: M20090917-0800
gdb版本(gdbserver版本和gdb版本一样)

book@book-desktop:~/sgy/second_video/j_gdb$ /bin/arm-linux-gdb 
GNU gdb (GDB) 7.8.1
Copyright (C) 2014 Free Software Foundation, Inc.

使用的源文件test_debug.c

#include 
void C(int *p)
{
    *p = 0x12;
}
void B(int *p)

{
    C(p);
}

void A(int *p)
{
    B(p);
}
void A2(int *p)
{
    C(p);
}

int main(int argc, char **argv)
{
    int a;

    int *p = NULL;
    A2(&a);  // A2 > C
        printf("a = 0x%x\n", a);

    A(p);    // A > B > C
    return 0;
}

编译应用程序

book@book-desktop:~/sgy/second_video/j_gdb$ arm-linux-gcc -g -o test_debug test_debug.c

新建工程也可以参考网上的教程,如果没有c project这个选项,需要安装一个cdt的插件

windows下的操作

arm-2014.05-29-arm-none-linux-gnueabi.exe

Eclipse IDE for C/C++ Developers
Version: Helios Service Release 2
Build id: 20110301-1815

$ arm-none-linux-gnueabi-gdb.exe
GNU gdb (Sourcery CodeBench Lite 2014.05-29) 7.7.50.20140217-cvs

linux上会有报一个错,应该是建立的是makefile工程,在进行debug的时候会自己去make我们的工程,这个问题应该不影响.见windows下的屏蔽错误.

开发板上的操作

windows上的操作

步骤是一样的,区别在于gdb工具得选windows上的exe文件,这个gdb版本可能跟gdbserver版本不一样,网上说会有问题出现,但是这样也能使用.后续出问题再说吧!
这里不要make工程,就不会报错了

报错

disable auto make

让程序在开发板上直接运行，当它发生错误时，令它产生core dump文件
然后使用gdb根据core dump文件找到发生错误的地方
在ARM板上：

1. ulimit -c unlimited
2. 执行应用程序 : 程序出错时会在当前目录下生成名为core的文件

在ubuntu下执行命令

book@book-desktop:~/sgy/second_video/j_gdb$ /bin/arm-linux-gdb ./test ./core
