I have been interested in learning how to code a mud for quite a while so I decided to jus ttry and run on on my own computer turn tweak with and learn as I go. First I chose the mud I like to play and build on and I chose the Dystopia code base. I downloaded the Dystopia 1.4 code from http://www.dystopiamud.dk/ and tried to compile it with cygwin. When I try to compile I get and error message. When I look at the log it reads this:

Now I have not actually done any coding on it yet and I was wondering if someone could give me a bit of help just sorting this out. Thanks

cl.exe is Microsoft Visual C++. How is this related to Cygwin?

Be much better off skipping cygwin altogether and getting the real thing. I've sat down with 2 other people that I consider capable when it comes to C, and still was not able to get the codebase to compile under cygwin. It just really does not like Diku and its derivatives, I guess.

Okay if it is to be done in C++ i have visual basic c++ installed i just don't know which file to open to start the project so that I can complie it. I know this is really a noob qustion but which file is the one that is to be opened so i can complie the whole thing.

I found Dystopia 1.4 to compile easily in cygwin with very little changes required.

strange when i went to do it i got an error
what change did you make

mostly what i get is the warring about logf and i am not sure how to take care of this unless i have to go through the eniter code and and the logf function

Either add '-fno-builtin-logf' into your makefile or rename the function/calls.

As for the changes I made, the ones I mostly remember were within comm.c

As for:

d:\mudding\dystopia\src\merc.h(25) : fatal error C1083: Cannot open include file: 'sys/cdefs.h': No such file or directory

I don't think you have all the packages required installed with your cygwin.

i have fixed the logf warnings by changi8ng them to log_f the major problem that comm.c:48:48 execinfo.h: No such file or directory.
the rest are warnings in comm.c about implicit declaration of function

#if !defined(__CYGWIN__) && !defined(__FreeBSD__)
#include <execinfo.h> // internal backtraces.
#endif

Onkay once i make all those changes that last error that i am getting that iam not sure how to handle is
gcc: unrecognized option -rdynamic

is this error in the makefile and if so how can i repair this.
thanks for your help so far

It's fine to just remove it.

Yes it is within the Makefile, sorry, forgot to write that too.

I have tried to look up on how to define the refernces that are telling me that are undifined. I have searched but no luck so far. the refrences are all in the comm.c file

they are _gethostbyaddr_r
_backtrace
_backtrace_symbols
those are all the erros that are showing

You'll need to use alternative calls to get around that issue.

gethostbyaddr() for example, but that isn't thread safe, so you'll need to lock the mutex whilst using it, just remember to release after.

As for your internal backtrace function, just wrap the contents of the function within the #if statements that you used on the header call.
