I'd like use this gdb python [1] , but can't put it work on Fedora 24, last problems mentioned are about Fedora 13 , can someone help me on pointing how I could use New_gdb_commands [2] ?

To use command like 'py-bt', 'py-list', etc. with GDB and Python 3, do the following:

1) Install GDB and python3-debuginfo: sudo dnf install gdb sudo dnf debuginfo-install python3-debuginfo

2) Run your Python 3 program and find out its PID

3) Attach to your Python 3 program with GDB: gdb python3 <pid-of-your-program>

NOTE: You'll probably get the following warning the first time: warning: the SELinux boolean 'deny_ptrace' is enabled, you can disable this process attach protection by: (gdb) shell sudo setsebool deny_ptrace=0 ptrace: Permission denied.

Execute the suggested command to disable 'deny_ptrace'.

4) Use commands described in [2] or https://docs.python.org/devguide/gd b.html
