当我关注苏巴姆·索尼将 emacs 与 Okular 连接起来的说明，当 emacs 尝试调用查看器“命令：（默认视图）”时，我收到错误消息“符号的函数定义是 void：nil”知道为什么会发生这种情况吗？
我的完整 .emacs 文件如下：
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(TeX-source-correlate-method (quote synctex))
'(TeX-source-correlate-mode t)

'(TeX-view-program-list (quote (("Okular" ("okular %o") "okular --unique %o#src:%n%b"))))

删除行
'(TeX-view-program-list (quote (("Okular" ("okular %o") "okular --unique %o#src:%n%b"))))
它的格式错误，而且如果你使用最新的 AUCTeX 版本（11.88 或更高版本），它就是无用的，Okular 开箱即用且配置正确。
