升壓/ thread.hpp失敗 '鐺++ -std = C++ 11 -stdlib = libc的++'

當試圖編譯鐺+的libC++（C++ 11模式）這一條線：升壓/ thread.hpp失敗 '鐺++ -std = C++ 11 -stdlib = libc的++'

#include <boost/thread.hpp>

鐺發出以下錯誤：

在我看來，這是在libc中++中的錯誤，因爲C++ 11確實需要這些功能是constexpr。

任何人都遇到同樣的問題，你能同意嗎？你知道任何修復嗎？

我鐺的版本是：

 
Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn) 
Target: x86_64-apple-darwin11.4.2 
Thread model: posix

隨着馬克思的提示，我找到了一個解決方法。在這種情況下定義BOOST_NO_CXX11_NUMERIC_LIMITS有幫助。所以它似乎是libC++的不完整。

根據Howard Hinnant的說法，這是一個libC++的bug，已經固定在主幹上。但是，當Apple可以將修復發佈到Xcode中時，還沒有任何信息。我將標記現在回答的問題。

編輯：該問題已修復在Apple LLVM 4.2版（clang-425.0.28）（基於LLVM 3.2svn）中。我目前的Xcode版本是4.6.3。

在這方面已修復了提示主幹libC++（http://libcxx.llvm.org）。 –

很高興知道。謝謝，霍華德。你知道蘋果什麼時候將解決方案發布到Xcode更新中嗎？ –

對不起，我不知道。 –

我使用boost在Xcode 4.3，並使用隨機TR1，最前一頁也建立自己的錯誤，但我定義的#define BOOST_HAS_TR1_RANDOM 1的#include之前，成功打造。你可以嘗試類似的方式，手動指出構建器有它自己的tr1實現。這可能是構建boost腳本的bug。

感謝您的提示。在我的情況下，'BOOST_NO_CXX11_NUMERIC_LIMITS'有幫助。但是，這與增強建設無關。使用boost頭文件會導致編譯失敗。 –
