我正在尝试安装texinfo 5.2，并且在./configure期间遇到了一些问题，我认为这与C编译器有关。从Snow Leopard升级时，我没有执行全新安装，所以也许这是问题的一部分。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
我已经阅读了与此有关的其他一些问题，因此尝试安装命令行工具。
ryansmacbook:~ ryan$ xcode-select -p
/Applications/Xcode.app/Contents/Developer
因此，尽管我正在运行从App Store安装的Xcode 5.1，但似乎未安装它们。根据我的阅读，应该安装命令行工具，但是我已经尝试过
$ xcode-select --install
无论如何，当我告诉我要安装它时，会弹出一条消息，提示“无法安装软件，因为当前无法从软件更新服务器获得该软件。”
我在http://www.topbug.net/blog/2013/04/14/install-and-use-gnu-command-line-tools-in-mac-os-x/上发现了我认为可能的解决方法，因此我执行了以下操作:
ryansmacbook:Tools ryan$ brew install coreutils

==> 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

但是我仍然有
./configure问题。以供引用，
$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

尽管前几天我曾尝试安装gcc-4.7，但目前它的安装位置为
/usr/gcc-4.7.2/bin/gcc-4.7
我不太确定如何从命令行将其作为命令运行，因为
$ gcc-4.7 --version
-bash: gcc-4.7: command not found
这就是我现在要得到的，但这可能不在这里或那里。
编辑:因为这不能直接回答我有关检查C编译器是否正常工作的问题，所以我没有将其提交为答案。我刚刚尝试了
brew install texinfo，它就像一个魅力。在这一点上，我真的不记得为什么我试图从源代码安装texinfo，也不记得我需要什么(也许是GNU Make相关的或Emacs相关的？)。 最佳答案
安装xcode后，我也遇到了同样的问题；我要做的就是运行gcc。然后，这要求我接受xcode许可证。之后，它运行良好。
希望这对某人有帮助。
