Error:

After going through my code I found that subhook_unprotect(void*, unsigned long) is not even in my code.

CodePudding user response：

If this is your code https://github.com/Zeex/subhook then it seems you are supposed to also include subhook_unix.c in your build. That file does define subhook_unprotect. So does subhook_windows.c but I'm assuming you are on a unix like platform.
