[英]No type named 'atomic' in namespace 'std'
Why doesn't 为什么不
std::atomic<int> index;
Work? 工作?
Currently using LLVM 3.1 with these params 当前将LLVM 3.1与这些参数一起使用
C Language Dialect GNU [-std=gnu99]
C++ Language Dialect [-std=c++11]
C++ Standard Library libc++(LLVM C++ standard library with C++11 support)
There are several things that need to be true for your code to work: 要使代码正常工作,需要满足以下几项要求:
You need to #include <atomic>
您需要#include <atomic>
You need to compile the code as C++11 or C++14 ( -std=c++11
or -std=c++14
(or c++0x
for older compilers)) 您需要将代码编译为C ++ 11或C ++ 14( -std=c++11
或-std=c++14
(或对于较旧的编译器为c++0x
))
Your compiler and standard library needs to support enough of C++11 to provide atomic
( http://clang.llvm.org/cxx_status.html ) 你的编译器和标准库需要的C ++ 11的支持足以提供atomic
( http://clang.llvm.org/cxx_status.html )
在我的Makefile中的CXXFLAGS中添加-std=c++11
>对我有用!
您需要按以下内容将其写入定义的变量。
std::atomic<std::int> index;
