免费c ++编译器的mac与开源许可证

问题描述：

有没有任何免费的c ++编译器的macs的许可证是开源的？
（基本上是其中一个 http://www.opensource.org/licenses/category）

Are there any free c++ compilers for macs whose license is open source? (basically one of these http://www.opensource.org/licenses/category)

我没有当前操作系统附带的DVD，它不会运行我已经有的xcode版本。

I don't have the DVD that came with my current OS, and it won't run the version of xcode I already have.

答

GCC 和 Clang + LLVM 都是开源C ++编译器。

GCC and Clang+LLVM are both open source C++ compilers.
