如何在gdb中禁用新的线程/线程退出消息？

Posted 2021-04-06

我正在调试一个应用程序，我得到了很多这样的消息：

[New Thread 0x7fffde152700 (LWP 11142)]
[Thread 0x7fffde152700 (LWP 11142) exited]

[New Thread 0x7fffde152700 (LWP 11157)]
[Thread 0x7fffde152700 (LWP 11157) exited]

我几乎从不对这些消息感兴趣。它们使得阅读输出的其余部分变得更加困难。它们可以改变程序的计时行为，使其难以重现和调试种族危险。如何禁用这些消息？

您可以在运行gdb时关闭线程事件：

set print thread-events off
