我正在尝试安装 texinfo 5.2，并且在 期间遇到了一些问题./configure，我认为这些问题与 C 编译器有关。当我从 Snow Leopard 升级时，我没有执行全新安装，所以这可能是问题的一部分。无论如何，这就是我所拥有的：
ryansmacbook:texinfo-5.2 ryan$ sudo ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" CPP="gcc -E" CXXCPP="g++ -E"

configure: error: in `/Users/ryan/Downloads/texinfo-5.2':

See `config.log' for more details
我已经阅读了与此相关的其他一些问题，因此我尝试安装命令行工具。
ryansmacbook:~ ryan$ xcode-select -p
/Applications/Xcode.app/Contents/Developer
所以看起来他们没有安装，虽然我正在运行从 App Store 安装的 Xcode 5.1。根据我的阅读，应该安装命令行工具，但我已经尝试过
$ xcode-select --install
无论如何，当我告诉它安装时，会弹出一条消息说“无法安装软件，因为它当前无法从软件更新服务器获得。”
我在http://www.topbug.net /blog/2013/04/14/ install-and-use-gnu-command-line-tools-in-mac-os- 找到了我认为可能的解决方法x/，所以我做了以下事情：
ryansmacbook:Tools ryan$ brew install coreutils
Warning: It appears you have MacPorts or Fink installed.

Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.

==> ./configure --prefix=/usr/local/Cellar/coreutils/8.22 --program-prefix=g --w
==> make install
==> Caveats
All commands have been installed with the prefix 'g'.
If you really need to use these commands with their normal names, you
can add a "gnubin" directory to your PATH from your bashrc like:
PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"
Additionally, you can access their man pages with normal names if you add
the "gnuman" directory to your MANPATH from your bashrc as well:
MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"
/usr/local/share/info/dir: Permission denied
==> Summary
/usr/local/Cellar/coreutils/8.22: 211 files, 10M, built in 2.4 minutes
但我仍然有这个./configure问题。
以供参考，
$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0

虽然前几天我确实尝试安装 gcc-4.7，但它目前生活在
/usr/gcc-4.7.2/bin/gcc-4.7
我不太确定如何让它从命令行作为命令运行，因为
$ gcc-4.7 --version
-bash: gcc-4.7: command not found
是我现在得到的，但这可能既不在这里也不在那里。
编辑：由于这并没有直接回答我关于检查 C 编译器是否工作的问题，所以我没有将其作为答案提交。我刚试过brew install texinfo，这就像一个魅力。在这一点上，我真的不记得我为什么要尝试texinfo从源代码安装，也不记得我需要它做什么（可能是与 GNU Make 相关或 Emacs 相关的东西？）。
