让 C 编译器在 OS X 上工作？

Question

我无法在 Mac OS X 10.11 和 XCode 8.2.1 到运行上正确获取 C 编译器。我安装了最新的 XCode 并删除了所有现有的 gcc 二进制文件，但仍然收到以下错误：

如何在我的配置中正确使用 C 编译器？

Answer 1

听起来您想从命令行运行 C 编译器（而不是 Xcode）。

转到 Apple 的开发者网站 download section 并下载 Command Line Tools (macOS 10.12) for Xcode 8.2。这可能需要一个有效的开发者帐户。

直接link目前是：Command Line Tools.
