I am getting the following error when I try to compile AFKMud 2.1.5:

bits.cpp: In function ‘void load_oldbits()’:
bits.cpp:145:28: error: ‘unlink’ was not declared in this scope

I am trying to compile it on a machine using the latest version of Lubuntu. Does anyone have a fix for this, or can you tell me what my first step in fixing this should be? Thank you in advance for your help!

I'm having similar problems as well...

looks like during the make process it's useing some functions from the files instead of just preparing them...

I should have all the cygwin stuff installed

Well, look up which system header unlink() is contained in for your particular operating system.

man unlink reports unistd.h, for Debian linux... and I would think it would be in a similar place for most unix-varients.

Okay, so the includes in bits.cpp look like this:

#if defined(WIN32)
#include <unistd.h>
#endif
#include <fstream>
#include "mud.h"
#include "bits.h"

So if I take out the if statement and just include unistd.h maybe it will work, except I get the same error in other files so I am going to have to grep for unlink and make the change in all those files. Is this correct?

EDIT: Okay I tried this, and I only needed to #include in two other files, pfiles.cpp, and db.cpp, and it compiles. I still get a bunch of warnings, but I will look at those later I suppose. I hope this helps.

I also had to remove comm.cpp line 44 to get it to compile without error... working now thanks...
