如何将Xcode上的编译器更改为gcc 7.3.0？

Question

I currently have Xcode 6.2.

First is there a way to check if this version of Xcode comes with gcc 7.3.0? And if it does have gcc 7.3.0, how do I set up Xcode so that gcc 7.3.0 becomes the default compiler?

However if my Xcode does not have gcc 7.3.0 how do I get gcc 7.3 and set up Xcode so that gcc 7.3.0 becomes the default compiler?

Answer 1

Xcode uses the LLVM Clang compiler, not gcc. gcc can be installed, the easiest way would be using either Homebrew or MacPorts . I'm not sure if there's any way to make it the default compiler though, especially not to use from inside Xcode. Is there some specific feature/reason why you need gcc 7.3?
