    header files

    I keep getting an error while compiling saying it can't find my defs.h file. In my main .cpp, I declare it like

    #include "defs.h"

    and this is my defs.h:

    #ifndef _DEFS_H
    #define _DEFS_H

    extern int rdesc[2];
    extern int rnum;
    extern int SetRoom();
    extern int DispRoom(int);

    #endif

    Is defs.h in the same directory as the .cpp file which includes it?

    Got that working, but now I get this:

    C:\TextGame\Game\engine.cpp(14) : warning C4551: function call missing argument list
    Linking...
    rooms.obj : error LNK2001: unresolved external symbol "int * rdesc" (?rdesc@@3PAHA)
    Debug/Game.exe : fatal error LNK1120: 1 unresolved externals
    Error executing link.exe.

    Game.exe - 2 error(s), 1 warning(s)

    Well look at your code, and the prototype, then figure out which is correct

    > unresolved external symbol "int * rdesc" (?rdesc@@3PAHA
    Put

    int rdesc[2];
    In one of your .cpp files
