Sorry for being so thin on details there. Was short on time. This is attempting to build on x64 MacOS 10.15/darwin. Sadly my ability to parse this is somewhat limited - but it seems like exploit24kpwn() needs to have a prototype or a prior declaration. It seems very unlikely given the age of this code that this is a new issue - so it is really puzzling.

Hey @Numbski I encountered the same issue.
I fixed it by adding #include "xpwn/img3.h" to xpwntool.c below the #include "xpwn/libxpwn.h"

Not sure if it's the intended fix, but atleast it compiles.

@planetbeing Thanks so much for merging #15. The fix works so you should be able to close this issue!
