製作Android操作系統源代碼失敗

我正在嘗試爲Android構建自定義ROM。目前，我已經安裝了我的編譯環境並下載了源代碼。製作Android操作系統源代碼失敗

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

一切工作的指令在執行source build/envsetup.sh和lunch，但在執行時make出現錯誤：

external/libcxx/include/cmath:679:9: note: using declaration 
using ::acos; 
     ^
external/libcxx/include/cmath:684:46: error: declaration conflicts with target of using declaration already in scope

您是否找到解決方案？ – RisingUp

看來，它是由Xcode的9見https://forums.developer.apple.com/thread/87814引起的。我也解決了這個問題。我打算切換到xcode 8.3。我用xcode 8.3和sdk 10.11編譯了android 7.1.2，沒關係，沒問題。

今天我已經驗證了xcode 8.3.3，可以構建android 7.1.2。祝你好運。 –

你救了我的命。謝謝。 – JohnWatsonDev
