我使用的target板子是s3c2410(arm9)，host PC是FC1. 下载了最新的gdb-6.3.tar.gz之后，解压进入gdb/gdbserver，./configure --target=arm-linux --host=arm-linux, 并修改Makefile 的CC为arm-linux-gcc，然后make，生成gdbserver可执行文件。 把gdbserver和所需lib库拷入root文件系统，并制作root.cramfs烧入flash中。 有一个简单的程序x.c，在host PC上arm-linux-gcc x.c -g生成文件a.out，拷入target中。然后进行下面的调试。可是出现问题，但不知道怎么解决。 在target板子上执行下面的操作： # ./gdbserver 172.16.0.1:5000 a.out Process a.out created; pid = 34 Listening on port 5000 Remote debugging from host 172.16.0.1 可以看出gdbserver应该是运行正常的。 在host PC上执行下面的操作： [root@localhost root]# gdb a.out GNU gdb Red Hat Linux (5.3.90-0.20030710.41rh) Copyright 2003 Free Software Foundation, Inc.

Use the "file" command. (gdb) 可是，从上面可以出现No symbol table is loaded错误。郁闷啊，一直未解决。 请斑竹和各位大侠不吝赐教，非常着急！
