[GRASS-dev] r.viewshed does not compile in GRASS 7 either

[William Kyngesburye]

Just tried something - it's definitely a clang problem.  Probably more strict, as I thought, about some C++ stuff by default.

It was working for me because of how Apple has the dev tools set up and how GRASS configure detects cc/c++.  For me, on Lion/Xcode 4.3, I have a bunch of symlinks:

/usr/bin/cc -> /usr/bin/clang
/usr/bin/c++ -> /usr/bin/clang
/usr/bin/gcc -> /usr/llvm-gcc-4.2/bin/llvm-gcc-4.2
/usr/bin/g++ -> /usr/llvm-gcc-4.2/bin/llvm-g++-4.2

And it appears that GRASS is preferring gcc/g++ in configuration.  llvm, as I understand, is more of an intermediate compiler made to closely emulate gcc behavior.

Maybe on Mt Lion, those symlinks are different so that GRASS uses clang instead of llvm.  It's possible I have leftovers from a previous Xcode.

What did GRASS find for CC and CXX?  (see include/make/platform.make)

What do you have for the /usr/bin compilers?
