c - 为什么在尝试使用 DDD 打开文件时会出现此错误？

Question

调试器:DDD。

64 位 Ubuntu Precise Pangolin 系统。

每当我尝试在 ddd 中打开一个非常简单的 C 程序时，我都会收到以下错误:

Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
Warning: Cannot convert string "%s" to type %s

Warning: Could not load font "-*-lucidatypewriter-medium-r-*-*-*-120-*-*-*-*-iso8859-*", using font "fixed" instead

此外，在终端上显示所有这些错误后，ddd 可以正常打开，但没有我想要调试的源文件。我在网上找不到解决办法!谢谢。

编辑:

我以 root 身份运行时出现上述错误。以普通用户身份运行时，我得到以下信息:

我想我是在@Fredrik 的帮助下解决的。

UTF-8 不兼容似乎是 ddd 中长期存在的错误。许多人报告了它，但似乎还没有人修复它。

我的代码没有显示在 ddd 中的原因是因为我在编译时没有使用 -g 选项。
