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.

此外，在终端上显示所有这些错误后，ddd打开正常，但没有我要调试的源文件。我在网上找不到这个解决方案！谢谢。

编辑：

以root身份运行时出现上述错误。当以普通用户身份运行时，我得到以下信息：

我想我在@Fredrik的帮助下弄明白了。

UTF-8不兼容似乎是ddd中一个长期存在的错误。很多人都报道了它，但似乎还没有人修复它。

我的代码未在ddd中显示的原因是因为我在编译时没有使用-g选项。

尝试使用DDD打开文件时，为什么会出现此错误？
