【问题描述】:
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,所有这些错误都显示在终端上后,ddd 可以正常打开,但没有我要调试的源文件。我在网上找不到解决方案!谢谢。
编辑:
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:

【问题讨论】:
-
你用什么命令来启动 DDD?
-
我正在使用以下内容:
ddd prac1.c &. -
...和
whoami的输出? (因为看起来您尝试以 root 身份运行 ddd,这可能不是您想要的) -
我以 root 身份运行。我尝试以普通用户身份运行,但我遇到了同样的问题,虽然不是 suid-bit 部分。
-
你不要在源代码上运行
ddd,试试ddd a.out(或任何你称之为可执行文件的东西)。
