emacs - Flymake 提示 X 不可用，即使配置为不使用 X

Question

在文本模式控制台 Emacs session 中运行 Flymake 模式，我如何告诉 Flymake 在文本控制台中显示其消息而不是尝试与 X 通信？

Emacs 23 运行在各种环境中，包括 Debian 和 Ubuntu。

我将flymake-gui-warnings-enabled设置为nil，但是当我flymake-display-err-menu-for-current-line 它提示:

X windows are not in use or not initialized

是的，我知道； Emacs 在没有 X 的情况下通过 SSH 连接运行。这就是我禁用 Flymake 使用 GUI 的原因。我怎样才能告诉 Flymake 不要尝试使用 GUI，而是在 Emacs 窗口中说出它必须说的话？

我发现“工具提示”错误消息无论如何都很烦人，所以我在我的 .emacs 中有这个，它在迷你缓冲区中显示 flymake 错误消息。这是我在某个地方从网上得到的东西。它被称为 flymake-cursor.el。信用属于第一个写它的人。您不需要我用作 flymake 助手的 Python 工具特有的 pyflake 位。主要功能是 show-fly-err-at-point，它允许您使用常规光标悬停在消息的突出显示行上。
