[ gpsdrive ] Compile problem: missing function drawmarkers()

[David Favro]

Hi!

I'm trying to compile from the 2.10pre4 tarball, and things seem to go
fine until, during the link of gmapview, I get:
gmapview.o: In function `expose':
.../gpsdrive-2.10pre4/src/util/gmapview.c:84: undefined reference to
`drawmarkers'

This baffles me because in grepping the source for drawmarkers, I see a
function declaration in src/lib_map/map.h and a number of calls to it,
but unless I'm mistaken, no implementation.  Can anyone shed any light
on what is happening here?  If from an external library, why would there
be a declaration in the header file?  Or am I not noticing the
implementation -- in which source file?  Or is there a missing preproc
macro or auto-generated code to alias it to another function?

Thanks very much in advance,
David
