All the credits for the symlink creation (the setupLibc.sh script) go to my friend Maxxvw. I don't take any credits on this part ! If you are an Hack The Box player and think this script is usefull, don't hesitate to drop a respect on his profile : https://www.hackthebox.eu/home/users/profile/258474
Obviously, all the credits for the three main projects used here go to their creators !
The installation of the Ropstar tool by XCT doesn't work properly with the libc-database project. There are problems of symbolic links by default. This script is here to correctly setup all the projects together.
Just execute the setup.sh script, it will setup all the ropstar project automatically (it will download ROPGadget, all the libc-database, ropstar and create the symlinks).
