GCC compiler

You already have a far more efficient compiler/loader in Clang/Clang++ installed by Xcode, and which is accessible from the Terminal.

If you install GCC via a package manager, you run the risk of having the extra management task of ensuring that you are actually keeping the Xcode and GCC libraries and include files separated during the compilation process. Not a pretty picture.

Hello Ralina129,

It sounds like you are trying to download something for Xcode. You may get better support if this question was in the Developer Forum, check out this link.
