Trouble with global-set-key to map meta-g with 'goto-line

[David Lee]

Hi, all
I am a beginner with GNU Emacs(21.3.1). I added this line to ~/.emacs
        (global-set-key [(meta-g)] 'goto-line)
but it doesn't work for me, and minibuffer gave this hint:
  Set face: default (M-g d), bold (M-g b), italic (M-g i)..

Seems that my settings didn't take effects.

Anything wrong?

[ I'm using SuSE 10.0, and I tried with failure under FC5, either. ]

Thanks in advance.
