Hi all,
I'm starting to develoop a set of command that
will be aggregate to have a distributed
hydrological model.
I'm now consider to write them in C++ instead of
C.
Can I do that in Grass? Just changing in the
makefile the compiler?
There is some region why not to use C++?
Thanks

The released versions of GRASS don't support compiling C++ code.
There are experimental changes in the CVS version to allow for C++,
but they suffer from a number of flaws, the most significant being
that all configure checks are done using C. If your C++ compiler needs
different switches, it won't work. IOW, if you use gcc for both C and
C++, it will probably work, otherwise it won't.
Also, C++ is still less portable (both as source code and compiled
binaries, particularly the latter) and less well supported than C. Not
everyone uses Linux and gcc; it's not uncommon for systems running a
commercial Unix variant not to have a C++ compiler, or to only have an
old (and quite possibly buggy) C++ compiler, or to have very poor
system support (linker, libraries, debugger etc) for C++.
