hey all, what im doing is moving my windows RoT 1.4 over to linux. it wont compile though, i've cd'ed to the src directory and typed 'make' and it doesnt work, i'm thinking its an error with the makefile, anyway, my question is how can i write a makefile so that it will compile under linux? i know it can be done, a year or so ago my coder did it for me with almost the exact same code

I suggest you dl a few similar codebases, and look at their makefiles, so you can learn how they work in a way relevant to you, and if it's too hard, then you cn just cut'n'paste to make one for your mud... they're fairly basic.

How does the makefile read? What errors is it generating?

Kas.

make: *** [comm.o] Error 1

Those are not makefile errors.

it compiles flawlessly on my computer and thats what it shows when i compile in shell...if not errors from the makefile, i dont know what the problem is...

Yeah, this isn't a makefile problem, it's because you're using a different compiler and different headers.
your linux types.h defines u_int itself, and I guess your windows version doesn't, You'll need to find where it's defined in your code, and add an:

#if defined(u_int)
#undefine(u_int)
#endif

or something along those lines (though this is only for the first error)
your comment and parse warnings will be due to different parsing of files by gdb from whatever you used in windows, you'll need to look at the specified files and lines to check them, unless some are caused by macroes.
I don't code crossplayform at present, so I don't know the exact details, but if you look at a stock merc codebase of some sort (along with mose all codebases) you'll find defines such as:

#if defined(TRADITIONAL)
#define const
#define args( list )            ( )
#define DECLARE_DO_FUN( fun )       void fun( )
#define DECLARE_SPEC_FUN( fun )     bool fun( )
#define DECLARE_SPELL_FUN( fun )    void fun( )
#else
#define args( list )            list
#define DECLARE_DO_FUN( fun )       DO_FUN    fun
#define DECLARE_SPEC_FUN( fun )     SPEC_FUN  fun
#define DECLARE_SPELL_FUN( fun )    SPELL_FUN fun
#endif

or

#if defined(macintosh)
#include 
#else
#include 
#endif

and similar...

Those are C compiler errors. The first one to fix is the line 77 of merc.h. You should comment out the definition of u_int. That will probably fix most of your errors. Secondly you've also got some re-declarations of common C runtime system prototypes, or some undeclared C runtime functions. Those can be fixed by removing the declarations and including the proper header files. See man page entries on the C runtime functions in question for which headers to include.

Also those declarations read, write, getpeername are probably OS dependent code demarcated #ifdef's depending on the parameters you pass the compiler (e.g. gcc -DWIN32 or gcc -DLinux)
