std :: thread错误（线程不是std的成员） [英] std::thread error (thread not member of std)

问题描述

我编译&安装gcc4.4使用macports。

I compiled & installed gcc4.4 using macports.

当我尝试编译使用 - > g ++ -g -Wall -ansi -pthread -std = c ++ 0x main.cpp。 ..：

When I try to compile using -> g++ -g -Wall -ansi -pthread -std=c++0x main.cpp...:

 #include <thread>
 ...
  std::thread t(handle);
  t.join();
 ....

编译器返回：

 cserver.cpp: In member function 'int CServer::run()':
 cserver.cpp:48: error: 'thread' is not a member of 'std'
 cserver.cpp:48: error: expected ';' before 't'
 cserver.cpp:49: error: 't' was not declared in this scope

但 std :: cout<< ...

任何人都可以帮助我？

推荐答案

gcc尚未完全支持std :: thread：

gcc does not fully support std::thread yet:

http：/ /gcc.gnu.org/projects/cxx0x.html

http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html

使用 boost::thread 。

编辑

虽然下面的代码用gcc 4.4.3编译并运行良好：

Although the following compiled and ran fine for me with gcc 4.4.3:

#include <thread>
#include <iostream>

struct F
{
  void operator() () const
  {
    std::cout<<"Printing from another thread"<<std::endl;
  }
};

int main()
{
  F f;
  std::thread t(f);
  t.join();

  return 0;
}

编译

g++ -Wall -g -std=c++0x -pthread main.cpp

code> a.out ：

Output of a.out:

Printing from another thread

你能提供完整的代码吗？也许在 ... s中有一些模糊的问题潜伏在

Can you provide the full code? Maybe there's some obscure issue lurking in those ...s?
