I installed the 6.3.0 version and I try to compile the r.example module with
the changes Clements suggest me to have sources with .cc extensions.
I have this error message, now (I think it depends by the compiler):

I read I should use g++ compiler, but i don't know what I have to change to use
it.

6.2.x doesn't have the pattern rules for C++.
I suggest using 6.3.x; otherwise, you'll need to figure out many of
the C++ issues yourself (raster/r.terraflow/Makefile will provide some
clues).
In general, new code should normally be written against the
development version (i.e. the Subversion trunk).
[However, once 6.3.0 is released, there will be two distinct
development branches, 6.4.x and 7.x. 7.x will be highly unstable for
quite a while, so the 6.4 branch should be used if you want the module
to be usable in the near future.]
