Subject: [GRASS-dev] viewshed and iostream issues
Viewshed does not immediately compile with the iostream library in
grass. Over the last years there were a few changes to it, but
were never merged them into the grass trunk because they did not
seem important enough at the time. Now that both viewshed and
terraflow use the same library, I don't think that it makes sense
to try to make viewshed compile with an older version; instead, I
would rather update the library. I looked over the grass svn
logs and the only significant changes to iostream that I could see
are the following:
1. #ifdef __MINGW32__ (windows compatibility)
2. char* replaced with std::string (Andy Danner's patch a few weeks
ago)
(is there anything else?)
I have merged these changes into my most recent version of iostream,
which I am attaching; it is split into headers
(include_iostream.tar), and cc files (lib_iostream.tar). If you
place them into grass_trunk/include/iostream/ and grass_trunk/lib/
iostream/ respectively, the library, terraflow and viewshed all
compile and run (macosx 10.4).
This is a start to get r.viewshed to compile and run and get some
feedback. If the general opinion is to keep the library
unchanged, I guess we'll have to modify viewshed, which is doable,
though not particularly exciting.

Laura, Will, and Paul,
I'm very much looking forward to being able to test out this new module.
