I'm getting a message from BLink that I don't understand.
my code includes the following:

...
#include <graphics/layers.h>
...
extern struct LayersBase *LayersBase;
...
   LayersBase=
   (struct LayersBase *) OpenLibrary ("layers.library",0);
   if (LayersBase == NULL) exit (FALSE);
...
   if(LayersBase)CloseLibrary(LayersBase);
...


But linking returns the following message:
...

Undefined symbols       First Referenced
_LayersBase              File 'Wrk:DJFonts.o'
Enter a DEFINE value for _LayersBase (default _stub):

...

I'm having no problems with other libraries. What gives with layers?
And what is it talking about with "(default _stub)"?

I assume that I'm missing some #define statement somewhere, but I
haven't a clue, even after searching through the include files.

Any help would be greatly appreciated.
