【问题描述】：
我似乎无法让代码块 13.12 在 clang++ 和 g++ 中正确编译 c++11。我在使用 clang++ 编译时附加了 -std=c++11 和 -stdlib=libc++。这会导致链接错误。对于 g++，当您添加 -std=c++11 或 -std=c++0x 时，编译器无法找到随机标头。当我在终端中同时使用 clang++ 和 g++ 手动编译代码时，这些错误都没有发生。
完整的链接器错误太长而无法发布，因此我将仅发布从 -v 调用中提供的信息。 在使用带有 -std=c++11 和 -stdlib=libc++ 的 clang++ 的代码块中：
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)

很遗憾，我无法在终端中对代码块 g++ 和 g++ 进行比较。
但是基于 clang 中两个不同编译的输出。在链接步骤中，代码块似乎没有使用 libc++ 库。您如何获得代码块以使用正确的库为 clang++ 链接？
我假设基于代码块中的 clang 问题 g++ 正在使用较旧的 c++ 03 库，即使在告诉编译器切换到 c++11 时也是如此。但不幸的是，我不知道如何确认。
【问题讨论】：
-
您应该在您的问题中提供链接器错误（或其中的示例）。可能相关：Some C++11 features missing when using Code Blocks 13.12。 C++11 也给 Eclipse 带来了问题。让事情正常工作很脆弱。
-
@jww 谢谢我添加了错误消息，现在我对问题的性质有了更好的了解，但不知道如何解决它。我查看了那个帖子，我认为我们遇到了不同的问题。但我不是 100% 确定。
-
@jww 我最终通过采纳您的建议和令人兴奋的建议找到了解决方案。
