Ann*_*ova 6 xcode configure clang osx-mountain-lion
在 MacOSX 10.8.5 上，升级到 Xcode 5.0.2（并升级/安装命令行工具（从 Xcode 首选项中））后，我通过从源配置安装 FFTW 3.3.3 和 Open MPI 1.6.5。我得到配置步骤中的两个 config.log 文件中出现相同类型的错误，这表明问题不在于我从官方网站下载的程序。
\n\n简而言之，我在两个日志中看到的第一个错误是：
\n\nconfigure:3750: checking for gcc\nconfigure:3766: found /usr/bin/gcc\nconfigure:3777: result: gcc\nconfigure:4006: checking for C compiler version\nconfigure:4015: gcc --version >&5\nApple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)\nTarget: x86_64-apple-darwin12.5.0\nThread model: posix\nConfigured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1\nconfigure:4026: $? = 0\nconfigure:4015: gcc -v >&5\nConfigured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1\nApple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)\nTarget: x86_64-apple-darwin12.5.0\nThread model: posix\nconfigure:4026: $? = 0\nconfigure:4015: gcc -V >&5\nclang: error: argument to \'-V\' is missing (expected 1 value)\nclang: error: no input files\nconfigure:4026: $? = 1\nconfigure:4015: gcc -qversion >&5\nclang: error: no input files\n当我输入：

\n\nalexey-sorokin:local admin$ gcc -V\nclang: error: argument to \'-V\' is missing (expected 1 value)\nclang: error: no input files\nalexey-sorokin:local admin$ clang -v\nApple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)\nTarget: x86_64-apple-darwin12.5.0\nThread model: posix\nalexey-sorokin:local admin$ which clang\n/usr/bin/clang\nalexey-sorokin:local admin$ gcc\nclang: error: no input files\n请参阅下面的 FFTW3.3.3 安装的 config.log 文件。OpenMPI1.6.5 的日志看起来非常相似，如果需要，我可以在下一条消息中上传它。我无法在正文中上传完整的日志，因此我将其缩短。\n非常感谢任何帮助/见解！谢谢你们！

问题是，Apple 将所有 GCC 调用重定向到 clang。配置认为它正在使用 GCC 并使用不兼容的语法，因此 Clang 失败。
您要么寻找更新版本的工具来解决该问题。或者您必须寻找特定的标志来告诉配置要使用哪个编译器。尝试设置 shell 变量CC，CXX或者可能有特定的配置标志，询问configure --help
另一种可能性是安装 GCC。使用 macports 或 homebrew 这更简单。但其中之一可能为您提供 MPI 和 FFTW，因此您可以使用它们。
