ubuntu - 在 ubuntu 中运行 ddd 时出现警告

Question

我刚刚在 Ubuntu 14.04 LTE 上安装了 ddd。如果我在命令行上运行它，我会收到以下警告:

user@user-VirtualBox:~/projects/myproject$ ddd
Warning: Cannot convert string "-*-helvetica-medium-r-*-*-*-120-*-*-*-*-iso8859-*" to type FontStruct

好像有很多人遇到这个问题，但我无法找到解决方案。这是基于谷歌搜索。

解决问题的任何帮助表示赞赏。

ddd 中似乎有一个与此相关的已知错误。见 https://lists.gnu.org/archive/html/ddd/2012-05/msg00001.html .基本上，它对安装的字体版本做出了硬编码假设。这些假设不适用于所有发行版。

对于 Debian 系统，安装 xfonts-100dpi 然后注销并重新登录应该可以消除这些消息。如果不是，您可能会受到上述问题的影响。
