在OSX到樹莓派

Question

交叉編譯我想配置我的OSX的機器上的環境，讓我交叉編譯爲樹莓派ARM6應用。當談到建立工具鏈時，我似乎正在跑進一堵牆。我正在使用crosstool-ng，並在安裝過程中遵循多個指南，但是我的問題歸結爲運行ct-ng build命令時。

一旦我運行此命令似乎一切都運行良好，直到我去試圖建立binutils的。一旦它達到這種依賴性，它最終將無法完成我所做的任何事情。

這是我看到的輸出中：

如果有人跑進這個問題，並知道如何解決它。這將非常感激。試圖從淠源建（型號A +已被證明非常艱難的，因爲它最終會崩潰）

謝謝。

Gold連接器cannot be compiled on Clang 6-7現在。如果鏈接器通過在Binary Utilities - Linkers to enable中被禁用，您應該可以繼續。
