arm-linux-gdb show "Don't know how to run"

[΀¶«Éœ]

1. I have install gdb5.3 as follow:
./configure --target=arm-linux
make
make install

2. I wrote a simply program "hello.c":
arm-linux-gcc -g -o hello hello.c

3. When i used the arm-linux-gdb to debug, it showed:

#arm-linux-gdb hello

./configure --target=arm-linux

This is a cross debugger.

Don't know how to run. Try "help target".

You have to tell it how to connect to your target. For arm-linux, you
should probably read the documentation for "gdbserver".
