Build issue

[behouba]

Hello,

I'm experimenting with unicorefuzz. This issue occurred while running setup.sh script:

....
[+] Building unicorn_mode
=================================================
UnicornAFL build script
=================================================

[*] Performing basic sanity checks...
[-] Error: Python setup-tools not found. Run 'sudo apt-get install python-setuptools'.

I've already installed Python 2 and Python 3, as well as 'python-setuptools' via apt-get and pip install. What am I doing incorrectly?

Probably you need python3-setuptools, too

Thank you @domenukk for the quick reply. I just installed python3-setuptools and still getting the same error message.

I've come across this issue as well and the root cause for me was the location of easy_install.py being within the python3 folder and not the python3.x folder. So, I changed the variable MYPYTHONPATH within AFLplusplus/unicorn_mode/build_unicorn_support.sh (line 114) to "/usr/lib/python3" and it worked!

$ find /usr/lib -name "easy_install.py"
/usr/lib/python3/dist-packages/setuptools/command/easy_install.py
/usr/lib/python3/dist-packages/easy_install.py
/usr/lib/python2.7/dist-packages/setuptools/command/easy_install.py
/usr/lib/python2.7/dist-packages/easy_install.py

$ echo `python -v </dev/null 2>&1 >/dev/null | sed -n -e '/^# \/.*\/os.py/{ s/.*matches //; s/os.py$//; p}'`
/usr/lib/python3.8/

I'll try and see if I can modify the one-liner :)

Edit: Here's a cheap hack for build_unicorn_support.sh:114

MYPYTHONPATH=`python -v </dev/null 2>&1 >/dev/null | sed -n -e '/^# \/.*\/os.py/{ s/.*matches //; s/os.py$//; p}' | sed -r 's/\.[0-9]{1,2}//g'`
