[GRASSLIST:4045] Re: More OGR lib compile fun

[Radim Blazek]

It seems that GRASS was configure as if it had GDAL, but 
definition is missing. Set your

grass51/include/Make/Platform.make:
GDALLIBS =
GDALCFLAGS =
USE_OGR =

grass51/include/config.h:
#undef HAVE_OGR   

But GDAL/OGR is very useful, I recommend to install GDAL.
