調試器：DDD。爲什麼在嘗試使用DDD打開文件時出現此錯誤？
64位Ubuntu精準穿山甲系統。
每當我試着在DDD打開一個非常簡單的C程序中，我得到以下錯誤：
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，國內開闢了罰款獲得在終端上顯示所有這些錯誤後，但沒有源我想調試的文件。我找不到這個在線的解決方案！謝謝。
編輯：
以root用戶身份運行時出現上述錯誤。以普通用戶身份運行時，我會得到以下內容：

你用什麼命令啓動DDD？ – slugonamission
我使用以下內容：'ddd prac1.c＆'。 – amorimluc
...和「whoami」的輸出？ （因爲它看起來像你試圖以root身份運行ddd，這可能不是你想要的） –
