GDB debug the called Program

Debug with GDBProgramYou can directly "GDB filepath" or "GDB filepath PID", but sometimes you need to be called by other programs to reproduce the problem.

You can use the following method to implement the above requirements.

Wait_gdb.py

#! /Usr/bin/ENV Python # Coding = utf-8import osimport timewhile true: OS. system ('ps aux | grep proc_name | grep-V "grep"> TMP ') FS = open ('tmp', 'R') line = FS. readline () FS. close () If line: pid = line. split () [1] OS. system ('gdb filepath % d-d source_code_path '% int (PID) Break

Run wait_gdb.py and wait until the gdb window is displayed when the program is called.
