Eventually, this README will have complete and more detailed information about building, installing, and playing the levels.
Currently, if you want to play around with them, take a look at package.py, which builds the levels, and dist/ which generally has an up-to-date build of each of the levels.
A Makefile is included that performs an automated build for both a local installation and for the MetaCTF web installation.
A list of users is passed in via the USERS environment variable, which will then build the binaries for each user listed.
Build binaries in obj/{foo,bar}/angr:
make USERS='foo bar' local
- You can go to the target directory (
obj/{foo,bar}/angr), you'll find the built binaries as well as the python files to play the levels
Build binaries in upper-level MetaCTF repo ../www/static/obj/{foo,bar}/angr:
make USERS='foo bar' web
Eventually, you'll find a walkthrough for playing some levels in walkthrough

While compiling using "make USERS=<user> local" you might have the following error:
fatal error: bits/libc-header-start.h: No such file or directory
One easy fix is to install the missing headers and libraries using:
sudo apt-get install gcc-multilib
