我正在尝试在我的Mac上为我的Raspberry Pi创建一个交叉编译器，我已经设法配置，构建和安装了crosstool-ng，但是在构建arm-unknow-linux-gnueabi工具链时，它失败了。 ./ct-ng build的输出是：

答案 0 :(得分：1)
想通了！ Crosstool-ng使用自己的grep（很奇怪，我知道），所以我删除了自己的grep（无法处理正则表达式），并为我构建的GNU grep添加了一个符号链接，位于usr/local/bin/grep
答案 1 :(得分：1)
我遇到了同样的错误信息，但却出现了不同的诊断并以完全不同的方式修复了它。我不确定谁是对的，但我会分享我的经验，希望能帮助别人。
经过多次搜索，我得出的结论是ct-ng正在使用系统grep，它没有Linux grep所具有的所有功能以及ct-ng所期望的功能。我的解决方案是使用Homebrew包管理器安装linux grep并让它覆盖系统grep。
我采取的步骤：
brew install grep --with-default-names。 --with-default-names标志告诉Homebrew覆盖系统grep。 （否则它会将其安装为＆＃34; ggrep＆＃34;以避免混淆）这实际上并没有删除你的系统grep，所以如果卸载Hombrew grep，系统grep仍然会在那里。执行此操作后，错误消失，我可以继续编译crosstool-ng。
答案 2 :(得分：0)
许多网站都建议对grep和gettext进行特殊处理，例如：在这里：
http://will-tm.com/cross-compiling-mac-os-x-mavericks/
安装crosstool-ng之前的一些事情
brew tap homebrew/dupes
brew install gettext
brew edit crosstool-ng
将此行添加到depends部分：
depends_on 'grep' => '--default-names'"
