Did anyone ever figure out what's going on with G_window_overlap?
I did a bad thing and recompiled a GRASS lib (I was trying to add -g
so that I could figure out some things with xdbx).
I'm trying to compile something:
cc -o s.voronoi OBJ.sun4/[bunch of dot-oh files] \
/home/soils/g/aggrass/grass4.1/src/libes/LIB.sun4/libgis.a \
/home/soils/g/aggrass/grass4.1/src/libes/LIB.sun4/libvect.a \
/home/soils/g/aggrass/grass4.1/src/libes/LIB.sun4/libdig2.a \
/home/soils/g/aggrass/grass4.1/src/libes/LIB.sun4/libdig_atts.a \
/home/soils/g/aggrass/grass4.1/src/libes/LIB.sun4/libdisplay.a -lm
ld: Undefined symbol
_G_window_overlap
So, I check the library
% ar t /home/soils/g/aggrass/grass4.1/src/libes/LIB.sun4/libgis.a \
| grep overlap
wind_overlap.o
seems to be there. Now I check the source:
% grep G_window_overlap \
/home/soils/g/aggrass/grass4.1/src/libes/gis/wind_overlap.c
G_window_overlap (window, N, S, E, W)
yep, this function *should* be in libgis.a
So, what's going on here?!? I'm recompiled several times (undoing
my -g addition), ran ranlib, etc, all to no avail.
Checking the archives, I see that people have run into this problem
before. Was the solution ever identified and applied?
I have Update 3 installed. This is on a sun4 (4.1.1) using Sun's ld.
Thanks,

I'm porting GRASS 4.1 to DEC alpha hardware using gcc for my compiler.
Has anyone else done this?
Specifically, at a first glance it looks like the functions G_window_overlap
and G_window_percentage_overlap are defined in src/libes/gis/wind_overlap.c
but are not declared extern anywhere -- a bunch of vector routines
that call them can't find them. Should they be declared in gisdefs.h?
Thanks for any help -- gcc is a lot stricter than the old DEC compilers,
and before I wade through all the information it spits out, I'd like to
know if someone has already done it.

I have extracted all the function declarations for the GIS, Raster,
Vector and Display libraries and collected them in one file
(most of them, anyway - might have missed one or two) because
I'm using GRASS from C++ (gcc-2.3.3 to be exact) and C++ is even more
strict about prototypes than gcc.
