在OS X上设置g ++ [英] Set up g++ on OS X

问题描述

我刚刚更新到OS X Mavericks，它似乎弄乱了我的整个编译器设置。我不仅需要重新安装JDK才能使用Java编译器，当我尝试使用GCC / G ++编译C / C ++时，出现以下错误：

  /usr/local/Cellar/gcc/4.7.2/gcc/lib/gcc/x86_64-apple-darwin12.2.1/4.7.2 /../../ .. /../include/c++/4.7.2/cwchar:46:19：致命错误：wchar.h：没有这样的文件或目录
  

不知道除了升级以外，还有什么想法弄糟了。我的问题是：我如何设置g ++在OS X上编译？如果已经设置好了，这里有什么问题？

如果我可以提供更多信息，请告诉我。

注意：我已经使用自制软件安装了gcc 4.7，但它似乎不起作用。当我特别使用 g ++ - 4.7 code.cpp 时，我得到了同样的错误。

解决方案安装Xcode的命令行工具（OS X Mavericks） - 2013年10月下旬为我解决了这个问题。这里是链接：

OSX：Xcode下载

经常提到 xcode-select --install 命令一直说它找不到所需的软件。

澄清：您需要使用Homebrew安装gcc-4.7。 CMD工具的最新版本的更新只修正了从Mountain Lion升级到Mavericks导致的兼容性问题。

I just updated to OS X Mavericks and it seems it messed up my whole compiler setup. Not only do I have to reinstall a JDK in order to use a Java compiler, I get the following error when I'm trying to compile C/C++ using GCC/G++:

/usr/local/Cellar/gcc/4.7.2/gcc/lib/gcc/x86_64-apple-darwin12.2.1/4.7.2/../../../../include/c++/4.7.2/cwchar:46:19: fatal error: wchar.h: No such file or directory

Not sure what to think other than upgrading messed it up. My question is: how do I set up g++ to compile on OS X? If it's already set up, what is the problem here?

If I can provide more information, please let me know.

Note: I've installed gcc 4.7 using homebrew, but it doesn't seem to work. When I use g++-4.7 code.cpp specifically, I get the same error.

解决方案

Installing the Command Line Tools (OS X Mavericks) for Xcode - Late October 2013 solved it for me. Here is the link:

OSX: Xcode Downloads

The often mentioned xcode-select --install command kept saying it cannot find the requested software.

To clarify: You need to already have gcc-4.7 installed using Homebrew. The update to the latest version of CMD Tools only fixes compatibility issues caused by upgrading from Mountain Lion to Mavericks.
