Project description
GDBFrontend is an easy, flexible and extensionable gui debugger.
Installing
PIP Package (Python Wheel)
You can install GDBFrontend with pip
.
pip install gdbfrontend
or if you want to install specific GIT snapshot:
python setup.py install
and you can run
gdbfrontend
Deb Package (Debian / Ubuntu / KDE Neon)
You can install GDBFrontend via deb package for Debian-based distributions.
You can install it from following commands:
echo "deb [trusted=yes] https://oguzhaneroglu.com/deb/ ./" | sudo tee -a /etc/apt/sources.list > /dev/null
sudo apt update
sudo apt install gdbfrontend
After installing with APT, you will get updates for new releases on APT upgrade.
You can get upgrades with following commands:
sudo apt update
sudo apt upgrade gdbfrontend
and you can run it:
gdbfrontend
Running From GIT
You can download latest source and run it.
Requirements
- GDB => 8.2 (with python3)
- python3
- tmux
You can run gdb-frontend with following commands:
git clone https://github.com/rohanrhu/gdb-frontend.git gdb-frontend
cd gdb-frontend
./gdbfrontend
and you can open it with:
http://127.0.0.1:5551/terminal/
or without terminal:

GDB Commands
GDBFrontend's GDB commands starts with gf-
.
gf-refresh
Refreshes all browser clients.
gf-theme [theme-name]
Switch to desired theme. For example: gf-theme light
, gf-theme red
or gf-theme default
for default theme.
gf-list-plugins
Lists all GDBFrontend plugins in the plugin directory.
gf-load-plugin [plugin-name]
Loads GDBFrontend plugin.
gf-unload-plugin [plugin-name]
Unloads GDBFrontend plugin.
GDBFrontend Python API
You can access GDBFrontend's Python API via gdbfrontend
module.
(gdb) python-interactive
>>> dir(gdbfrontend)
For example, you can get all client sockets like this:
>>> gdbfrontend.api.globalvars.httpServer.ws_clients
{1: <server.GDBFrontendSocket object at 0x...>}
or you can get all plugins:
>>> gdbfrontend.plugin.getAll()
['hello', 'theme_light', 'theme_red']
Security with Sharing Sessions
You can use --credentials=USER:PASS
option for adding HTTP authentication to your debugger session.
Note: Your browser will ask same credentials for two times.
Troubleshooting
Blocking GDB shell/main-thread
Most of GDBFrontend functions are thread-safe and work on GDB's main-thread. So, if you run something that is blocking on the GDB shell, GDBFrontend functions have to wait it until finish.
You will get this warning when a thread-safe GDBFrontend function needs to work and you are blocking GDB's main thread.
(gdb) shell
$ ...
[GDBFrontend] GDB main thread is bloocking. (If you are running something (like shell) in GDB shell, you must terminate it for GDBFrontend to continue work properly.)
When you exit shell, blocking GDBFrontend functions will continue working.
Zombie Processes
Sometimes GDB and gdb-frontend may not be closed correctly. In this case, you can terminate gdb-frontend shell.
tmux kill-session -t gdb-frontend
Expression Evaluater Performance Tips
If you are using ExpressionEvaluater with very long depth expanded variables/members, your scroll and evaluater window move performance may be affected bad for pointer visualization. In this situation, you can turn off signal and slot pointings for that evaluater window.
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.
WSL
You can use gdb-frontend on WSL (Windows Subsystem for Linux).
Issues about WSL
- On WSL 1, Random port option is not usable on WSL becasue
/proc/net/tcp
interface is not working on WSL. (WSL 2 does not has this problem.)
Versioning
Since v0.2.0-beta, GDBFrontend switched to a new versioning strategy.
Reading Versions
In vX.Y.Z-STABILITY
:
X
is major versions, changes long term with major features and enhancements.Y
is main versions that include new features and enhancements.Z
is bugfix releases of main versions.STABILITY
is stability level of the release. (alpha
,beta
,rcN
,stable
)
