Hello, I'm trying to debug kernel (vmlinux) with kgdb I am using gdb version 7.9.1.
These are the logs in eclipse (host) and in target: In eclipse I see the following: Python Exception <type 'exceptions.ImportError'> No module named gdb: /home/ubuntu/dtu/jjj/gdb-7.9.1/gdb/gdb: warning: Could not load the Python gdb module from `/home/tigran/gdb/share/gdb/python'. Limited Python support is available from the _gdb module. Suggest passing --data-directory=/path/to/gdb/data-directory. GNU gdb (GDB) 7.9.1 Copyright (C) 2015 Free Software Foundation, Inc.
