使用 Eclipse CDT + GDB 到达断点时如何停止执行单个线程

Question

我正在使用 gdb 7.4 在 Eclipse Oxygen 中调试多线程 C++ 应用程序 默认行为是当到达断点时所有线程都停止，但是，我希望只有到达断点的线程停止，所有其他线程继续运行。

怎么可能？

怎么可能？

(gdb) set non-stop on 

默认情况下，不间断模式是关闭的。您希望它开启，请参阅 gdb 内置帮助：

(gdb) help set non-stop 
Set whether gdb controls the inferior in non-stop mode.
When debugging a multi-threaded program and this setting is
off (the default, also called all-stop mode), when one thread stops
(for a breakpoint, watchpoint, exception, or similar events), GDB stops
all other threads in the program while you interact with the thread of
interest.  When you continue or step a thread, you can allow the other
threads to run, or have them remain stopped, but while you inspect any
thread's state, all threads stop.

In non-stop mode, when one thread stops, other threads can continue
to run freely.  You'll be able to step each thread independently,
leave it stopped or free to run as needed.
