emacs 21中的emacs限制模式

Question

For my job, I HAVE to use CentOS 5 as a development machine. CentOS 5 only comes with emacs 21, and I don't want to compile from source or use an RPM not approved for this OS, so I'm stuck with emacs 21.

The trouble is, (global-linum-mode 1) doesn't work.

I've installed linum.el and whitespace.el . Whitespace works fine, and if I do Mx linum-mode it works. How come emacs can't automatically just turn linum-mode on from the .emacs file? Isn't there a way to do that? Every page I come across says, 'yes, by entering (global-linum-mode t) ' into your .emacs file, but that doesn't work in emacs 21.

Ideas?

Answer 1

用easy-mmode-define-global-mode替换define-globalized-minor-mode ，然后重试。

Answer 2

Check out http://www.emacswiki.org/emacs/LineNumbers . There are a number of line numbering implementations that date from before linum.el was made part of the standard emacs distribution.

In particular, line-num.el from the above page claims to be compatible with emacs 21.
