How do I install g++ on MacOS X?

Question

I want to compile C++ code on MacOS X, using the g++ compiler. How do I install it?

Answer 1

xcode is now available for free from the app store. Just "buy it" (for free) and it will download. To get the command line tools go into preferences/downloads and "install command line compiler tools".

Instead of gcc you are using clang, but it works the same.
