Question

我从AIX 6.1上的C应用程序的核心转储中获得以下回溯。我正在运行GDB 6.0。

当我尝试运行线程应用所有bt full 时，它只返回NOTHING。

我需要在这里找出错误，因为它只发生在以下场景中：

应用程序等待消息大约30个小时没有任何内容，然后出现消息，似乎不喜欢“醒来”。

我很想知道导致问题的另一个问题是什么......

非常感谢任何帮助

你从哪里得到gdb？对于aix来说，gdb很难/难以编译。例如，它有一个AIX线程选项。我记得，你必须明确告诉./configure使用该选项。

另外，正如alk指出的那样，请确保您拥有正确的可执行文件＆lt; =＆gt;核心文件。确保您具有相同的LIBPATH，就像应用程序在转储时所做的那样。

fullcore也有帮助（我假设你已经拥有）。

AIX 6.1：CORE DUMP - GDB“线程应用所有bt full”返回NOTHING？
