@Corona688: What the createsim script basically does is
- Tell the user we're going to build it
- Run make
meaning it's completely unnecessary.
@OneDreamCloser: apparently this piece of software requires an include file only found on BSD (MacOS X is a derived from that). Unless you find some compatibility libraries, you won't have any luck compiling it. And even then it might be doubtful if it uses proprietary Apple technology.
