Ubuntu下gdb远程调试--warning: Could not load vsyscall page because no executable was specified解决方案

1. 首先安装gdbserver

apt-get install gdbserver

2. 编译-g 程序

gcc -g test_gdb.c -o test_gdb

源码如下：

#include "Util.h"

void p1()

{

int j = 0;

char *p;

*p = '5';

printf("%p %c",p,*p);

{

j++;

}while(j < 10);

}

void p2()

{

int j = 0;

while(j < 20)

{

j = j + j*j;

}

int main(int argc,char **argv)

{

CreateGerneralThread(p1);

CreateGerneralThread(p2);

while(1)

{

sleep(1);

}

return 0;

}

3. 在server端执行下面语句：

gdbserver 192.168.110.138:9002 ./test_gdb

会出现下面这句话

tiger@ubuntu:/mnt/hgfs/e/Lessons/MyExercise/UtilLibs/THREAD$ gdbserver 192.168.115.250:9002 ./test_gdb

Process ./test_gdb created; pid = 23562

Listening on port 9002

在client端执行下面几句话：

1. gdb

出现下面这些东西：

[root@localhost ~]# gdb

try using the "file" command first.

0xb7fdf1d0 in ?? ()

2. 执行：

　　target remote:192.168.115.250:9002

3. 执行:

　　symbol-file remote:192.168.115.250:9002

4. 可以调用类似continue , break 等命令了
