gdb错误：无法执行epoll_wait：（4）系统调用中断

Question

I am unable to run my code in debug using gdb because of the following error:

Unable to execute epoll_wait: (4) Interrupted system call

Any ideas on how to solve this?

Thanks

You should check the epoll_wait return value, then if it's -1 compare errno to EINTR and, if so, retry the system call. This is usually done with continue in a loop.
