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 = ;
char *p; *p = ''; printf("%p %c",p,*p);
do
{
j++;
}while(j < ); } void p2()
{
int j = ; while(j < )
{
j = j + j*j;
} } int main(int argc,char **argv)
{ CreateGerneralThread(p1); CreateGerneralThread(p2); while()
{
sleep();
}
return ;
}
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

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
