Hello,
I would like to compile an add-on module to my installation of GRASS
6.4.3, specifically the r.cva and r.prominence modules developed by Mark
Lake and Benjamin Ducke.

You can use both modules through the SEXTANTE/GRASS interface
in gvSIG OADE 2010:
http://www.oadigital.net/software/gvsigoade
For instructions, see the PDF manual that will be copied
to your computer as part of the installation process.
Note that gvSIG OADE 2010 is now unmaintained. There is
a successor called gvSIG CE (www.gvsigce.org), which
will release a stable version in a few weeks (inshallah).
It will also include r.cva and r.prominence. But if you
need them right now, use OADE 2010. It works fine.
Hoping that I can compile these modules myself, I've ran into a number
of problems trying to compile OSgeo4w64 on my system. I'm guessing it
has something to do with the 64bit processor, but I'm also not too
experienced with compiling open source software for this to be easy in
the first place.
Both modules have not seen updates for a while, so I am not sure
that they will compile on GRASS 6.4.3 at all at this moment.
Unfortunately, OSgeo4w64 includes some MS Visual C/C++ projects
and some MSVC runtimes/DLLs, whereas the GRASS binaries that ship
with gvSIG use only open source MinGW DLLs, so I don't think you
can just copy the GRASS modules over (but it's worth a try).
I was wondering if anyone would be kind enough to compile the above
modules, and produce a working binary that I could implement into GRASS
here on my Windows 64-bit system. Or at the very least, point me in the
right direction for how to go about this myself.
You should probably try r.viewshed, for which windows binaries are
pre-compiled [1] and should be installable with g.extension. See also [2].
I would say the same: Try if r.viewshed suits your needs first.
It's much more efficient than r.cva (though not as flexible and
convenient for cumulative analyses).
Alternatively, if you opt for gvSIG: Look in the SEXTANTE group
"Visibility & Lighting". There are many other options in there.
Best,
Ben
