GEF (pronounced "Jeff") is a set of commands for x86/64, ARM, MIPS,
PowerPC and SPARC to assist exploit developers and reverse-engineers when using
old school GDB. It provides additional features to GDB using the Python API to
assist during the process of dynamic analysis and exploit development.
Application developers will also benefit from it, as GEF lifts a great part of
regular GDB obscurity, avoiding repeating traditional commands, or bringing out
the relevant information from the debugging runtime.
Some of GEF features include:
- One single GDB script.
- Fast limiting the number of dependencies and optimizing code to make the
commands as fast as possible.
- Provides more than 50 commands to drastically change your experience in GDB.
- Easily extendable to create other commands by providing more comprehensible
layout to GDB Python API.
- Built around an architecture abstraction layer, so all commands work in any
GDB-supported architecture such as x86-32/64, ARMv5/6/7, AARCH64, SPARC,
MIPS, PowerPC, etc.
- Suited for real-life apps debugging, exploit development, just as much as CTF.
===> The following configuration options are available for gef-2026.01:
OPTIONALDEPS=on: Install optional dependencies for extra functionalities
===> Use 'make config' to modify these settings
all: remove explicit versions in USES=python for "3.x+"
The logic in USES=python will automatically convert this to 3.8+ by
itself.
Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
