linux下eclipse C++ 多线程调试

初学linux编程，想要用linux下eclipse C++ 多线程调试，发现相关资料很少，所以想写一篇这样的文章

If you use eclipse CDT, you probably understand that eclipse isn't a debugger, it's just an application front-end, specifically to GDB. So when debugging C++ programs, you're actually just using GDB in a more comfortable manner. If you ever have to debug a
multithreaded program in eclipse CDT, you'll realize that things quickly get hectic because when you hit a breakpoint, all threads stop, and when one tries to execute a single line in a specific thread, it also runs the other threads. In order for it to work
properly, the threads have to be able to be run arbitrarily and exlusively-so that when the programmer executes a single line, it only executes the specific thread.

So, by default, gdb's settings by default leave the "scheduler-locking" turned off. If you debug multithreaded applications you'll understand that this must be on in GDB in order for the desired behavior to be achieved. How does one run this command:

set scheduler-locking on

in GDB within eclipse CDT?
