3) How to compile AFLFuzz with Python support
|
||||
---------------------------------------------
|
||||
|
||||
You must install the python 3.7 or 2.7 development package of your Linux
|
||||
You must install the python 3 or 2 development package of your Linux
|
||||
distribution before this will work. On Debian/Ubuntu/Kali this can be done
|
||||
with either:
|
||||
apt install python3.7-dev
|
||||
apt install python3-dev
|
||||
or
|
||||
apt install python2.7-dev
|
||||
apt install python-dev
|
||||
Note that for some distributions you might also need the package python[23]-apt
|
||||
|
||||
A prerequisite for using this mode is to compile AFLFuzz with Python support.
|
||||
|
||||
The afl Makefile performs some magic and detects Python 3.7 and 2.7 if it is
|
||||
in the default path and compiles afl-fuzz with the feature if available (which
|
||||
is /usr/include/python2.7 for the Python.h include and
|
||||
/usr/lib/x86_64-linux-gnu for the libpython2.7.a library)
|
||||
The AFL++ Makefile detects Python 3 and 2 through `python-config` if is is in the PATH
|
||||
and compiles afl-fuzz with the feature if available.
|
||||
|
||||
In case your setup is different set the necessary variables like this:
|
||||
PYTHON_INCLUDE=/path/to/python2.7/include LDFLAGS=-L/path/to/python2.7/lib make
|
||||
PYTHON_INCLUDE=/path/to/python/include LDFLAGS=-L/path/to/python/lib make
