Maxima Problems

maxima-mode C-c C-d 帮助系统出错：

Search failed: "Menu:"

原因很有可能是没有设置正确的 maxima-info-dir. 把这些行加入 .emacs:

(setq maxima-info-dir "/usr/share/info/")

注意！ "/usr/share/info/" 最后的 "/" 必不可少！

Emacs 的 maxima-mode 起动 maxima 进程时出现错误：

Symbol's value as variable is void: comint-output-filter-functions

这很有可能是因为 maxima 起动失败。看下一个问题：

maxima 起动时出现 crash:

很有可能是因为 ~/.inputrc 里出现

$if Bash
...
$endif

这样的条件语句。这有可能时是 Maxima readline 部分的一个 bug. 我已经向 Maxima 的 mailing list 报告了这个问题。
