tmux kill-session -t gdb-frontend

GDB-Related Issues and Tips

• GDB does not give sources of linked object until stepping a line that calls a function from the linked object once. You can add break point a line and step it once, then you will see sources from linked object hereafter during the session.

Windows

In fact, gdb-frontend is able to run on Windows but there are some serious issues in the GDB’s Windows version those avoid using gdb-frontend on Windows. Of course you can use gdb-frontend on WSL if you are using Windows 10.

Issues About Windows-GDB

• GDB’s main-thread is being blocked during running process. (gdb-frontend has an interrupting mechanism to fixing this but it is not enough yet.)
• Windows-GDB’s prompt is being blocked during running process and there are some issues about interrupting the application.
• Current release of Windows-GDB contains Python2. New GDB 9 have Python3 but it is not released yet.
