I had a similar issue when building things from source, and it was because I forgot to install the updated command line tools after upgrading to Yosemite and xcode 6.1. Try this in your command line:
我在从源代码构建东西时遇到了类似的问题，这是因为我在升级到 Yosemite 和 xcode 6.1 后忘记安装更新的命令行工具。在命令行中试试这个：
xcode-select --install
That will download and install the command line tools and may fix your problem.
这将下载并安装命令行工具，并可能解决您的问题。

If you set MACOSX_DEPLOYMENT_TARGET=10.9in your environment prior to compiling, the shared object linking should work properly.
如果您MACOSX_DEPLOYMENT_TARGET=10.9在编译之前在您的环境中进行设置，则共享对象链接应该可以正常工作。

if you're using Homebrew, simply:
如果您使用的是 Homebrew，只需：
brew upgrade gcc

This was enough for me, and it doesn't require any symlink:
这对我来说已经足够了，它不需要任何符号链接：
export CC=/Applications/Xcode.app/Contents/Developer/usr/bin/gcc
After that, just run the command as usual.
之后，只需像往常一样运行命令。

This solve my problem: I link gcc with /Applications//Xcode.app/Contents/Developer/usr/bin/gcc
这解决了我的问题：我将 gcc 与 /Applications//Xcode.app/Contents/Developer/usr/bin/gcc 链接
cd /usr/local/bin
ln -s /Applications//Xcode.app/Contents/Developer/usr/bin/gcc gcc

The patch you are trying to use is for patching the source code of GCC, and you are trying to use it to patch the compiled binary. That won't work.
您尝试使用的补丁是用于修补 GCC 的源代码，而您正在尝试使用它来修补已编译的二进制文件。那行不通。
In theory the process would be
理论上这个过程是
- Download source tarball of GCC compiler
- apply the patch to it
- compile GCC
- Install the compiled GCC
- 下载 GCC 编译器的源码包
- 将补丁应用到它
- 编译 GCC
- 安装编译好的 GCC
However, you are unlikely to be able to do this since you cannot run the compiler in order to compile a newer copy of itself. Catch-22!
但是，您不太可能做到这一点，因为您无法运行编译器来编译自身的较新副本。第22条！
Searching google for 'gcc yosemite' I found a number of references to possible solutions, eg. enter link description here. I'm afraid I am no mac expert so I cannot judge the quality of these solutions.
在谷歌搜索“gcc yosemite”，我发现了许多可能的解决方案的参考，例如。在此处输入链接描述。恐怕我不是 mac 专家，所以我无法判断这些解决方案的质量。

I am also getting the warning "couldn't understand kern.osversion `14.0.0'" on GFORTRAN compilations while running Yosemite (10.10.1) with Xcode 6.1 and GCC 5.0. The compiler, however, generates functioning executable code and it seems to run correctly. Maybe you can just ignore the warning?
在使用 Xcode 6.1 和 GCC 5.0 运行 Yosemite (10.10.1) 时，我还在 GFORTRAN 编译中收到警告“无法理解 kern.osversion `14.0.0'”。然而，编译器会生成可运行的可执行代码，并且它似乎可以正确运行。也许你可以忽略警告？

I solved an issue by linking
我通过链接解决了一个问题
export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2

It seems to want a current version of XCode command line tools. When I first typed "make" after installing Yosemite I got a warning and a dialog box saying that I did not have XCode command line tools and asked if I wanted to install them. I did so, and everything worked.
它似乎需要当前版本的 XCode 命令行工具。当我在安装 Yosemite 后第一次输入“make”时，我收到一个警告和一个对话框，说我没有 XCode 命令行工具，并询问我是否想安装它们。我这样做了，一切都奏效了。
However one user did not get this dialog and instead got the error message as shown. The "xcode-select --install" did not work, so it seems like it may have kept the outdated command line tools and header files.
但是，一位用户没有收到此对话框，而是收到了如图所示的错误消息。“xcode-select --install”不起作用，所以它似乎保留了过时的命令行工具和头文件。
The MACOSX_DEPLOYMENT_TARGET=10.9 solution did work for him. However the compiles seemed to be a lot slower.
MACOSX_DEPLOYMENT_TARGET=10.9 解决方案确实对他有用。然而，编译似乎要慢得多。

I had this issue, installed Xcode cli tools (xcode-select --install), and still had issues. I'd upgraded from Yosemite to Mojave, and uninstalling an older version of the compiler worked for me:
我遇到了这个问题，安装了 Xcode cli 工具 ( xcode-select --install)，但仍然有问题。我从优胜美地升级到 Mojave，卸载旧版本的编译器对我有用：
brew uninstall apple-gcc42
Hope this helps someone!
希望这可以帮助某人！
