Gef loaded, `gef help' to start, `gef config' to configureģ7 commands loaded (15 sub-commands), using Python engine 3.5 You should see the following header and prompt $ gdb -q /bin/ls To check that GEF has been correctly installed, simply start a new gdb Otherwise, it willĪutomatically disable all the gef commands that require this invalid module. Gef will assume the module installations are valid. Have problems while installing those modules. Gef works out of the box, please do not send issues to this project if you Please refer to each project for installation and troubleshooting guides. Some of those modules can be installed through python-pip. Ropper - an improved version of ROPgadget.Highly recommended to install the following modules (but not required): (gdb) pi import urllib.request as u, tempfile as t g=t.NamedTemporaryFile(suffix='-gef.py') open(g.name, 'wb+').write(u.urlopen('').read()) gdb.execute('source %s' % g.name)Ī few commands were added to GEF to extend its capabilities. $ echo source ~/.gdbinit-gef.py > ~/.gdbinitĪlternatively from inside gdb directly: $ gdb -q One-time setup script # via the install script The latest, though you're more likely to encounter a bug. $ echo 'source /path/to/gef.py' > ~/.gdbinit Then sourcing the file from your ~/.gdbinit. The best way to use GEF is by cloning the git repository from GitHub, and
If you see an error here, it means that your GDB installation does not support Python. $ gdb -nx -ex 'pi print(sys.version)' -ex quit This should display your version of Python compiled with gdb. You can verify it with the following command: $ gdb -nx -ex 'pi print(sys.version)' -ex quit Gef-legacy won't provide new features, and only functional If you absolutely require GDB + Python 2,
For most people, simply using yourĭistribution package manager should be enough.Īs of January 2020, GEF officially doesn't support Python 2 any longer, due to It must beĬompiled with Python 3.6 or higher support. There is NO mandatory dependency to have gef running contrarily to other projects.Ī simple recent GDB compiled with Python scripting support will do.
