我正在尝试使用Crosstool-NG设置工具链。我在Crosstool-NG 1.22.0上使用OS X 10.11.4。
我使用homebrew安装，所以我不确定为什么我缺少依赖项。当我尝试构建时，这是我的输出：
$ ct-ng build
[INFO ] Performing some trivial sanity checks
[INFO ] Build started 20160504.172530

[ERROR]

[00:02] / make: *** [build] Error 1
如果需要，我可以附加我的.config文件，但我相信错误就在此之前。
我已经尝试过跑步了：
$ brew install gcc --with-java
但错误仍然存在。我一直在线学习一些教程，主要是this一个，所以也许它有错误。我检查了build.log输出，它几乎与shell输出相同。这个问题有一个已知的解决方案，还是我忘记了某个步骤？
