我正在尝试通过 Homebrew 在 OSX Mavericks 上通过命令安装 GDB brew install homebrew/dupes/gdb。安装过程中弹出以下错误消息：
gdb requires special privileges to access Mach ports.
You will need to codesign the binary. For instructions, see:

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/info/bfd.info
Target /usr/local/share/info/bfd.info
is a symlink belonging to binutils. You can unlink it:
brew unlink binutils
To force the link and overwrite all conflicting files:
brew link --overwrite gdb
To list all files that would be deleted:
brew link --overwrite --dry-run gdb
Possible conflicting files are:
/usr/local/share/info/bfd.info -> /usr/local/Cellar/binutils/2.24/share/info/bfd.info
/usr/local/share/info/configure.info -> /usr/local/Cellar/binutils/2.24/share/info/configure.info
==> Summary
答案1
该消息询问是否brew应使用从 GDB 安装的文档覆盖从binutils安装的文档，是的，覆盖这些文档是安全的。覆盖 中的系统链接通常是安全的brew，如果它破坏了某些东西，您可以轻松地重新安装该软件包。
