1118.0. "Invalid library format???" by PCBUOA::BAYJ (Jim, Portables) Fri May 23 1997 11:40

    I am porting a V1.0 VC++ app to VC++ 4.1.  I am getting the error:
    
    	C:\MSVC\LIB\graphics.lib : warning LNK4003: invalid library format;
    library ignored
    
    The application has an include for the header file <graph.h>, and gets
    an unresolved external symbol at link time for a routine called
    _clearscreen, presumably because it can't read the library.
    
    This library actually came with VC++ 1.0, which I also have installed,
    and I have my include and lib file pointer lists pointing to the 1.0
    include and lib directories (AFTER the 4.1 libraries, that is).
    
    I can't find documentation for the graphics package on the 4.1 CD, but
    there are several articles on it that contain code samples which use
    the __clearscreen call.  Apparently graph.h pointed to a library of
    console mode graphics primitives (actually, its more likely they were
    used for "screen" graphics before Windows and Consoles existed, or at
    least were popular).
    
    Does anyone know anything about this graphics library GRAPHICS.LIB? Is
    there something I can do to VC++ or to the graphics library to make it
    usable?
    
    Fortunately, there is an article that explains writing your own version
    of __clearscreen for console mode, and that seems to be the only
    external reference that was not found.  But if the routine is sitting
    there waiting to be used, I'd like to use it if I could.

    hi jeb,
    
    i have VC++ 5.0 and i can't find graph.h or graphics.lib.
    creating your own __clearscreen may be the only way.
