Debugger not supported

*Describe the bug TendaAC1518.py: ql.debugger=":9999" Error: Debugger not supported

Sample Code

You should use ql.debugger = "gdb:9999" instead.

I used tencent Cloud machine。 Does it matter?

[Ryze-T]

ql.debugger = "gdb:0.0.0.0:9999"

this code can solve it

But When I used Ida Pro debug. tendaac18.py，It errors：

The reason is that execve is re-loading Qiling, which then tries to re-open the debugger. There was a line there to prevent that, but it was removed for some reason (... by me, apparently).

https://github.com/qilingframework/qiling/blob/e2b0e4d5adc3e2557c95528a052a7d792aec99fb/qiling/os/posix/syscall/unistd.py#L519

Uncomment that line, and see if it works.

When I open debug options and gdb connect it and run, It doesn't work:

I don't understand the problem you encounter, and the purpose of the attached screenshots is unclear to me. Can you please clarify the situation?

Hey @KA2010, let me know what is the exact scenario in which you encounter the problem. Maybe we should re-open this one.
