[GRASS-user] AdvancedViewshedAnalysis

[Rebecca Rennell]

Hi GRASS-Users

Apologies for cross-posting. 

My difficulty is with install AdvancedViewshedAnalysis extension using GEM within GRASS 6.4.ORC6

command 'gem6' is not recognised

command 'gem install AdvancedViewshedAnalysis.tar' produces the following error message

ERROR:  Could not find a valid gem 'AdvancedViewshedAnalysis.tar' (>= 0) in any repository

I have an older version of GRASS (GRASS 6.3.0). From here the command
'gem6 -i AdvancedViewshedAnalysis.tar -v' begins to install and then aborts with the following error message:

ERROR: Compilation failed for these module(s):
/private/tmp/grass.extension.Mngj89/AdvancedViewshedAnalysis/src/raster/r.cva
/private/tmp/grass.extension.Mngj89/AdvancedViewshedAnalysis/src/raster/r.prominence
Run 'make' manually in each module's directory for details.
make: *** [default] Error 1

I've now run make in both modules (I think), but I still get the same error message.  I also don't understand why the tar file is recognised from GRASS 6.3 but not 6.4. I'm almost certainly doing something very stupid - any help gratefully received!

Thanks
Becky
