我正在尝试在我的osx机器上配置一个环境，这将允许我为Raspberry Pi交叉编译arm6应用程序。在设置工具链时，我似乎正在奔跑。我正在使用crosstool-ng并在设置上遵循多个指南，但我的问题归结为运行ct-ng构建命令时。
一旦我运行此命令，一切似乎都运行正常，直到我尝试构建binutils。一旦达到这种依赖性，它最终将失败，无论我做什么。
这是我看到的输出：

如果有人遇到此问题并知道如何修复它。非常感谢。试图在Pi上建立源代码（模型A +已证明非常难以最终崩溃）
谢谢。

金链接器cannot be compiled on Clang 6-7目前。如果通过t - x中的ct-ng menuconfig禁用了链接器，您应该可以继续。
