Hi,
I am running GRASS GIS 7.3.svn (r68671M) on MacOSX 10.10.5
I have used g.extension to install r.surf.nnbathy and v.surf.nnbathy,
and the following command indicates that it is in the right place
(accessible from GRASS command line):
r.surf.nnbathy --help
Description:
Interpolates a raster map using the nnbathy natural neighbor
interpolation program.
Keywords:
vector, surface, interpolation, natural, neighbor
Usage:
r.surf.nnbathy input=name output=name [algorithm=string] [--overwrite]
[--help] [--verbose] [--quiet] [--ui]
Flags:
--o Allow output files to overwrite existing files
--h Print usage summary
--v Verbose module output
--q Quiet module output
--qq Super quiet module output
--ui Force launching GUI dialog
Parameters:
input Name of input raster map
output Name of output raster map
algorithm Settings
options: l,nn,ns
default: nn
l: Linear
nn: Sibson natural neighbor
ns: Non-Sibsonian natural neighbor
However, issuing e.g. [r.surf.nnbathy input=dem_ct output=dem_nn]
GRASS 7.3.svn (skeifa_river_02):~ > r.surf.nnbathy input=dem
output=dem_nn
"nnbathy" is performing the interpolation now. This may take some
time...

I suspect I need to install the nn-c library.
Does anyone have step-by-step cookbook type instructions or any
guidelines on how to do this on MacOSX?
Cheers,
Jon Eiriksson
