在ubuntu中运行ddd时发出警告

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

似乎有很多人遇到了这个问题,但我无法找到解决方案.这是基于谷歌搜索.

任何帮助解决问题的人都表示赞赏.

ddd中似乎有一个与此相关的已知错误。参见https://lists.gnu.org/archive/html/ddd/2012-05/msg00001.html。基本上，它会对安装的字体版本进行硬编码假设。这些假设并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消除这些消息。如果不是这样，您可能会受到上述问题的影响。
