请教GDB调试的问题

humingmao

最近一直在建嵌入式交叉开发环境(在linux(fedora4)与ARM(S3C44B0)之间的连接)，可是GDB(gdbserver/gdb)调试一直弄不好，有哪位好心人可以帮帮我,不胜感激！我的情况时：

client:
/mnt/hu> gdbserver :2000 hello &
[30]
/mnt/hu> Process hello created; pid = 31

server:
[root@localhost arm]# arm-elf-gdb

(gdb) file hello.gdb
Reading symbols from hello.gdb...done.

(gdb) target remote 192.168.253.2:2000
Remote debugging using 192.168.253.2:2000
0xce30050 in _start ()

client:
/mnt/hu> Process hello created; pid = 31
Remote debugging from host 192.168.253.8
code at 0xce30040 - 0xce35d20, data at 0xce35d24

server:
(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y
Starting program: /root/arm/hello.gdb
You can't do that without a process to debug.
(gdb)

client:
/mnt/hu> Process hello created; pid = 31
Remote debugging from host 192.168.253.8
code at 0xce30040 - 0xce35d20, data at 0xce35d24
Killing inferior

sh 16: Child 30 died
为什么输入run命令是会出现：You can't do that without a process to debug.
