在ubuntu中运行ddd时发出警告

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中似乎存在与此相关的已知错误.请参阅
https://lists.gnu.org/archive/html/ddd/2012-05/msg00001.html.基本上,它会对安装了哪种版本的字体进行硬编码假设.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消除这些消息.如果不是,您可能会受到上述问题的影响.
