Question

我正在使用c ++ 0x标志在多个平台上编译项目。我遇到麻烦的唯一平台是Mac。它似乎对其他编译器允许滑动的事情感到不安。我正在使用Mac 10.8，Qt 5.3.2以及以下版本的clang。

clang -v
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix

这是它产生的错误。

我遇到同样的问题，似乎与clang和c ++ 11有关。

我的情景： - Mac osx 10.10.1优胜美地 - 使用命令行工具6.1的Xcode 6.1 - Gnu赚3.81 - gcc -v：配置为： - prefix = / Applications / Xcode.app / Contents / Developer / usr --with-gxx-include-dir = / usr / include / c ++ / 4.2.1 Apple LLVM 6.0版（clang-600.0.56）（基于LLVM 3.5svn）目标：x86_64-apple-darwin14.0.0 线程模型：posix 没有自制软件，没有macports，只是手工编译的一些依赖项。

我正在尝试为x86_64编译。

有任何线索吗？

我的想法可以用gcc而不是clang重新编译每个依赖项，但我仍然没有时间测试它，也许它对你有用;）

代码在Windows和Linux上编译，但不在Mac上编译
