制作Android操作系统源代码失败

我正在尝试为Android构建自定义ROM。目前，我已经安装了我的编译环境并下载了源代码。制作Android操作系统源代码失败

我在下面https://source.android.com/source/building#build-the-code

一切工作的指令在执行source build/envsetup.sh和lunch，但在执行时make出现错误：

using ::acos;

您是否找到解决方案？ – RisingUp

看来，它是由Xcode的9见https://forums.developer.apple.com/thread/87814引起的。我也解决了这个问题。我打算切换到xcode 8.3。我用xcode 8.3和sdk 10.11编译了android 7.1.2，没关系，没问题。

今天我已经验证了xcode 8.3.3，可以构建android 7.1.2。祝你好运。 –

你救了我的命。谢谢。 – JohnWatsonDev
